100-515: Akeman Street is a Roman road in southern England between the modern counties of Hertfordshire and Gloucestershire . It is approximately 117 kilometres (73 mi) long and runs roughly east–west. Akeman Street linked Watling Street just north of Verulamium (near modern St Albans ) with the Fosse Way at Corinium Dobunnorum (now Cirencester ). Evidence suggests that the route may well have been an older track, metalled and reorganised by

200-416: A transit , a surveyor tried to achieve straightness by looking along the rods and commanding the gromatici to move them as required. Using the gromae they then laid out a grid on the plan of the road. If the surveyor could not see his desired endpoint, a signal fire would often be lit at the endpoint in order to guide the surveyor. The libratores then began their work using ploughs and, sometimes with

300-878: A 6-mile (10 km) stretch between Tackley and Stonesfield that is part of the Oxfordshire Way . 51°53′10″N 1°11′31″W  /  51.88624°N 1.19202°W  / 51.88624; -1.19202 Roman road At the peak of Rome's development, no fewer than 29 great military highways radiated from the capital, and the empire's 113 provinces were interconnected by 372 great roads. The whole comprised more than 400,000 kilometres (250,000 miles ) of roads, of which over 80,500 kilometres (50,000 mi) were stone-paved. In Gaul alone, no less than 21,000 kilometres (13,000 mi) of roadways are said to have been improved, and in Britain at least 4,000 kilometres (2,500 mi). The courses (and sometimes

400-885: A Roman official to be sent, on service either civil or military, where we do not find roads. They reach the Wall in Britain ; run along the Rhine , the Danube , and the Euphrates ; and cover, as with a network, the interior provinces of the Empire. A road map of the empire reveals that it was generally laced with a dense network of prepared viae . Beyond its borders there were no paved roads; however, it can be supposed that footpaths and dirt roads allowed some transport. There were, for instance, some pre-Roman ancient trackways in Britain, such as

500-407: A directional straightness. Many long sections are ruler-straight, but it should not be thought that all of them were. Some links in the network were as long as 55 miles (89 km). Gradients of 10%–12% are known in ordinary terrain, 15%–20% in mountainous country. The Roman emphasis on constructing straight roads often resulted in steep slopes relatively impractical for most commercial traffic; over

600-413: A domestication that served goals such as reducing stagnant bogs that fostered waterborne diseases, making regions more habitable for human settlement, and reduce high frequency of floods. Not long before Tulla went to work on widening and straightening the river, heavy floods caused significant loss of life. Four diplomatic treaties were signed among German state governments and French regions dealing with

700-467: A great public service like that of the roads. Gaius Gracchus , when Tribune of the People (123–122 BC), paved or gravelled many of the public roads and provided them with milestones and mounting-blocks for riders. Gaius Scribonius Curio , when Tribune (50 BC), sought popularity by introducing a Lex Viaria , under which he was to be chief inspector or commissioner for five years. Dio Cassius mentions that

800-529: A layer of fine concrete, the nucleus, went onto the pavement or statumen . Into or onto the nucleus went a course of polygonal or square paving stones, called the summa crusta . The crusta was crowned for drainage. An example is found in an early basalt road by the Temple of Saturn on the Clivus Capitolinus . It had travertine paving, polygonal basalt blocks, concrete bedding (substituted for

900-513: A regulation width (see Laws and traditions above), but actual widths have been measured at between 3.6 feet (1.1 metres) and more than 23 feet (7.0 metres). Today, the concrete has worn from the spaces around the stones, giving the impression of a very bumpy road, but the original practice was to produce a surface that was no doubt much closer to being flat. Many roads were built to resist rain, freezing and flooding. They were constructed to need as little repair as possible. Roman construction took

1000-426: A road, though privately constructed, became a public road when the memory of its private constructors had perished. Siculus Flaccus describes viae vicinales as roads " de publicis quae divertunt in agros et saepe ad alteras publicas perveniunt " (which turn off the public roads into fields, and often reach to other public roads). The repairing authorities, in this case, were the magistri pagorum or magistrates of

In Alemannic, the deletion of the ending -n in pausa is a recent development; the form Rn is largely preserved in Lucernese dialects. Rhing in Ripuarian is diphthongized, as is Rhei, Rhoi in Palatine . While Spanish has adopted the Germanic vocalism Rin- , Italian, Occitan, and Portuguese have retained

The modern German diphthong Rhein (also used in Romansh ) Rein, Rain

1300-649: Is significantly shortened from its natural course due to a number of canal projects completed in the 19th and 20th century. The "total length of the Rhine", to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometers (766 miles) by the Dutch Rijkswaterstaat in 2010. Its course is conventionally divided as follows: The Rhine carries its name without distinctive accessories only from

1400-732: Is sometimes called Rhinesee ("Lake Rhine"). Besides the Seerhein , the Radolfzeller Aach is the main tributary of Untersee . It adds large amounts of water from the Danube system to the Untersee via the Danube Sinkhole . Reichenau Island was formed at the same time as the Seerhein, when the water level fell to its current level. Lake Untersee is part of the border between Switzerland and Germany , with Germany on

1500-526: The Aare . The Aare more than doubles the Rhine's water discharge, to an average of slightly more than 1,000 m /s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn , the highest point of the Rhine basin . Between Eglisau and Basel , the vast majority of its length,

1600-665: The Anterior Rhine and the Posterior Rhine join and form the Alpine Rhine. The river makes a distinctive turn to the north near Chur . This section is nearly 86 km long, and descends from a height of 599 meters to 396 meters. It flows through a wide glacial Alpine valley known as the Rhine Valley ( German : Rheintal ). Near Sargan a natural dam, only a few meters high, prevents it from flowing into

1700-483: The Etruscans . The Viae terrenae were plain roads of leveled earth. These were mere tracks worn down by the feet of humans and animals, and possibly by wheeled carriages. The Viae glareatae were earthen roads with a gravel surface or a gravel subsurface and paving on top. Livy speaks of the censors of his time as being the first to contract for paving the streets of Rome with flint stones, for laying gravel on

1800-815: The Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin. The southern half of the Upper Rhine forms the border between France ( Alsace ) and Germany (Baden-Württemberg). The northern part forms the border between the German states of Rhineland-Palatinate in the west on the one hand, and Baden-Württemberg and Hesse on

1900-509: The Obersee with the 30 cm lower Untersee . Distance markers along the Rhine measure the distance from the bridge in the old city center of Konstanz. For most of its length, the Seerhein forms the border between Germany and Switzerland. The exception is the old city center of Konstanz, on the Swiss side of the river. The Seerhein emerged in the last thousands of years, when erosion caused

2000-650: The Rhine knee , a major bend, where the overall direction of the Rhine changes from west to north. Here the High Rhine ends. Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows north as Upper Rhine through the Upper Rhine Plain , which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg,

2100-400: The Rhine knee , the river turns north and leaves Switzerland altogether. The High Rhine is characterized by numerous dams. On the few remaining natural sections, there are still several rapids . Over its entire course from Lake Constance to the Swiss border at Basel the river descends from 395 m to 252 m. In the center of Basel, the first major city in the course of the stream, is

2200-531: The Second Triumvirate obliged the Senators to repair the public roads at their own expense. The second category included private or country roads, originally constructed by private individuals, in whom their soil was vested and who had the power to dedicate them to the public use. Such roads benefited from a right of way in favor either of the public or of the owner of a particular estate. Under

2300-692: The Via Labicana in 421 BC; and the Via Salaria in 361 BC. In the Itinerary of Antoninus , the description of the road system is as follows: With the exception of some outlying portions, such as Britain north of the Wall, Dacia , and certain provinces east of the Euphrates, the whole Empire was penetrated by these itinera (plural of iter ). There is hardly a district to which we might expect

2400-750: The canton of Ticino is drained by the Reno di Medel , which crosses the geomorphologic Alpine main ridge from the south. All streams in the source area are partially, sometimes completely, captured and sent to storage reservoirs for the local hydro-electric power plants. The culminating point of the Anterior Rhine's drainage basin is the Piz Russein of the Tödi massif of the Glarus Alps at 3,613 meters (11,854 ft) above sea level. It starts with

2500-415: The cantons . They could require the neighboring landowners either to furnish laborers for the general repair of the viae vicinales , or to keep in repair, at their own expense, a certain length of road passing through their respective properties. With the conquest of Italy, prepared viae were extended from Rome and its vicinity to outlying municipalities, sometimes overlying earlier roads. Building viae

2600-424: The censor who had ordered their construction or reconstruction. The same person often served afterwards as consul, but the road name is dated to his term as censor. If the road was older than the office of censor or was of unknown origin, it was named for its destination or the region through which it mainly passed. A road was renamed if the censor ordered major work on it, such as paving, repaving, or rerouting. With

2700-463: The civil engineer looked over the site of the proposed road and determined roughly where it should go, the agrimensores went to work surveying the road bed. They used two main devices, the rod and a device called a groma , which helped them obtain right angles. The gromatici , the Roman equivalent of rod men, placed rods and put down a line called the rigor . As they did not possess anything like

2800-680: The confluence of the Rein Anteriur/Vorderrhein and Rein Posteriur/Hinterrhein next to Reichenau in Tamins . Above this point is the extensive catchment area of the headwaters of the Rhine. This area belongs almost exclusively to the Swiss canton of Grisons ( Graubünden ), ranging from Saint-Gotthard Massif in the west via one valley lying in the canton of Ticino and Sondrio ( Lombardy , Italy) in

2900-464: The 19th century. While it was slightly modified during the Roman occupation, it was not until the emergence of engineers such as Johann Gottfried Tulla that significant modernization efforts changed the shape of the river. Earlier work under Frederick the Great surrounded efforts to ease shipping and construct dams to serve coal transportation. Tulla is considered to have domesticated the Upper Rhine,

3000-614: The Anterior Rhine and the Rhine as a whole. The Posterior Rhine rises in the Rheinwald below the Rheinwaldhorn . The source of the river is generally considered north of Lai da Tuma/Tomasee on Rein Anteriur/Vorderrhein , although its southern tributary Rein da Medel is actually longer before its confluence with the Anterior Rhine near Disentis . The Anterior Rhine arises from numerous source streams in

3200-643: The Danube comprised much of the Roman Empire 's northern inland boundary , and the Rhine has been a vital navigable waterway bringing trade and goods deep inland since those days. The various castles and defenses built along it attest to its prominence as a waterway in the Holy Roman Empire . Among the largest and most important cities on the Rhine are Cologne , Rotterdam , Düsseldorf , Duisburg , Strasbourg , Arnhem , and Basel . The variants of

3300-480: The High Rhine forms the border between Germany and Switzerland . Only for brief distances at its extremities does the river run entirely within Switzerland; at the eastern end it separates the bulk of the canton of Schaffhausen and the German exclave of Büsingen am Hochrhein on the northern bank from cantons of Zürich and Thurgau , while at the western end it bisects the canton of Basel-Stadt . Here, at

3400-663: The Latin Ren- . The Gaulish name Rēnos ( Proto-Celtic or pre-Celtic *Reinos ) belongs to a class of river names built from the PIE root *rei- "to move, flow, run", also found in other names such as the Reno in Italy. The grammatical gender of the Celtic name (as well as of its Greek and Latin adaptation) is masculine, and the name remains masculine in German, Dutch, French, Spanish and Italian. The Old English river name

3500-875: The Posterior Rhine is joined by the Albula , from the east, from the Albula Pass region. The Albula draws its water mainly from the Landwasser with the Dischmabach as the largest source stream, but almost as much from the Gelgia , which comes down from the Julier Pass . Numerous larger and smaller tributary rivers bear the name of the Rhine or equivalent in various Romansh idioms, including Rein or Ragn , including: Next to Reichenau in Tamins

3600-512: The Rhine into Lake Constance forms an inland delta . The delta is delimited in the west by the Alter Rhein and in the east by the modern canalized section of the Alpine Rhine ( Fußacher Durchstich ). Most of the delta is a nature reserve and bird sanctuary . It includes the Austrian towns of Gaißau , Höchst and Fußach . The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In

3700-774: The Rhine defines much of the Franco-German border , after which it flows in a mostly northerly direction through the German Rhineland . Finally in Germany, the Rhine turns into a predominantly westerly direction and flows into the Netherlands where it eventually empties into the North Sea . It drains an area of 9,973 km . Its name derives from the Celtic Rēnos . There are two German states named after

3800-583: The Ridgeway and the Icknield Way . The Laws of the Twelve Tables , dated to about 450 BC, required that any public road (Latin via ) be 8 Roman feet (perhaps about 2.37 m) wide where straight and twice that width where curved. These were probably the minimum widths for a via ; in the later republic, widths of around 12 Roman feet were common for public roads in rural regions, permitting

Its course passes through towns and villages including Hemel Hempstead , Berkhamsted , Tring , Aylesbury , Alchester (outside modern Bicester ), Stonesfield (where a large Roman villa was discovered around 1712), Chesterton , Kirtlington , Ramsden and Asthall . Parts of the A41 road between Berkhamsted and Bicester use the course of the former Roman road, as did the Sparrows Herne turnpike between Berkhamsted and Aylesbury. A minor road between Chesterton and Kirtlington also uses its course. Other parts are in use as public footpaths , including

4000-607: The area around the river was made more habitable for humans on flood plains as the rate of flooding decreased sharply. On the French side, the Grand Canal d'Alsace was dug, which carries a significant part of the river water, and all of the traffic. In some places, there are large compensation pools, for example, the huge Bassin de compensation de Plobsheim in Alsace. The Upper Rhine has undergone significant human change since

It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee . The cut-off Old Rhine at first formed a swamp landscape. Later an artificial ditch of about two km

4200-405: The causeway to more than 5 feet (1.5 metres) above the marsh. In the provinces, the Romans often did not bother with a stone causeway but used log roads ( pontes longi ). The public road system of the Romans was thoroughly military in its aims and spirit. It was designed to unite and consolidate the conquests of the Roman people, whether within or without the limits of Italy proper. A legion on

4300-432: The censorial responsibility passed to the commanders of the Roman armies and later to special commissioners, and in some cases perhaps to the local magistrates. In the provinces, the consul or praetor and his legates received authority to deal directly with the contractor. The care of the streets and roads within the Roman territory was committed in the earliest times to the censors. They eventually made contracts for paving

4400-420: The centers Basel, Strasbourg and Mannheim-Ludwigshafen. Strasbourg is the seat of the European Parliament , and so one of the three European capitals is located on the Upper Rhine. The Upper Rhine region was changed significantly by a Rhine straightening program in the 19th century. The rate of flow was increased and the ground water level fell significantly. Dead branches were removed by construction workers and

4500-603: The changes proposed along the Rhine, one was "the Treaty for the Rectification of the Rhine flow from Neuberg to Dettenheim"(1817), which surrounded states such as Bourbon France and the Bavarian Palatinate . Loops, oxbows , branches and islands were removed along the Upper Rhine so that there would be uniformity to the river. The engineering of the Rhine was not without protest, farmers and fishermen had grave concerns about valuable fishing areas and farmland being lost. While some areas lost ground, other areas saw swamps and bogs be drained and turned into arable land. Johann Tulla had

4600-725: The charges for using the roads. Costs of services on the journey went up from there. Financing road building was a Roman government responsibility. Maintenance, however, was generally left to the province. The officials tasked with fund-raising were the curatores viarum . They had a number of methods available to them. Private citizens with an interest in the road could be asked to contribute to its repair. High officials might distribute largesse to be used for roads. Censors, who were in charge of public morals and public works, were expected to fund repairs suâ pecuniâ (with their own money). Beyond those means, taxes were required. A via connected two cities. Viae were generally centrally placed in

4700-423: The city proper) who were both part of the collegia known as the vigintisexviri (literally meaning "Twenty-Six Men"). Augustus, finding the collegia ineffective, especially the boards dealing with road maintenance, reduced the number of magistrates from 26 to 20. Augustus abolished the duoviri and later granted the position as superintendent (according to Dio Cassius) of the road system connecting Rome to

4800-412: The city wall and the first milestone beyond. In case of an emergency in the condition of a particular road, men of influence and liberality were appointed, or voluntarily acted, as curatores or temporary commissioners to superintend the work of repair. The dignity attached to such a curatorship is attested by a passage of Cicero . Among those who performed this duty in connection with particular roads

4900-437: The condition of the public highways. Their names occur frequently in the inscriptions to restorers of roads and bridges. Thus, Vespasian , Titus , Domitian , Trajan , and Septimius Severus were commemorated in this capacity at Emérita. The Itinerary of Antoninus (which was probably a work of much earlier date and republished in an improved and enlarged form under one of the Antonine emperors ) remains as standing evidence of

5000-427: The construction of sewers and removed obstructions to traffic, as the aediles did in Rome. It was in the character of an imperial curator (though probably armed with extraordinary powers) that Corbulo denounced the magistratus and mancipes of the Italian roads to Tiberius . He pursued them and their families with fines and imprisonment and was later rewarded with a consulship by Caligula , who also shared

5100-421: The countryside. The construction and care of the public roads, whether in Rome, in Italy, or in the provinces, was, at all periods of Roman history, considered to be a function of the greatest weight and importance. This is clearly shown by the fact that the censors, in some respects the most venerable of Roman magistrates, had the earliest paramount authority to construct and repair all roads and streets. Indeed all

5200-415: The creek Aua da Russein (lit.: "Water of the Russein"). In its lower course, the Anterior Rhine flows through a gorge named Ruinaulta (Flims Rockslide). The whole stretch of the Anterior Rhine to the Alpine Rhine confluence next to Reichenau in Tamins is accompanied by a long-distance hiking trail called Senda Sursilvana . The Posterior Rhine flows first east-northeast, then north. It flows through

5300-415: The first paved road—the Appian Way . Unless these allusions are just simple anachronisms, the roads referred to were probably at the time little more than levelled earthen tracks. Thus, the Via Gabiana (during the time of Porsena ) is mentioned in about 500 BC; the Via Latina (during the time of Gaius Marcius Coriolanus ) in about 490 BC; the Via Nomentana (also known as "Via Ficulensis"), in 449 BC;

5400-444: The flow is diverted off the island of Mainau into Lake Überlingen. Most of the water flows via the Constance hopper into the Rheinrinne ("Rhine Gutter") and Seerhein. Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake. The Rhine carries very large amounts of debris into the lake – over three million cubic meters (110,000,000 cu ft) annually. In

5500-416: The goal of shortening and straightening the Upper Rhine. Early engineering projects the Upper Rhine also had issues, with Tulla's project at one part of the river creating rapids, after the Rhine cut down from erosion to sheer rock. Engineering along the Rhine eased flooding and made transportation along the river less cumbersome. These state projects were part of the advanced and technical progress going on in

5600-411: The gravel), and a rain-water gutter. Romans preferred to engineer solutions to obstacles rather than circumvent them. Outcrops of stone, ravines, or hilly or mountainous terrain called for cuts and tunnels. An example of this is found on the Roman road from Căzănești near the Iron Gates . This road was half carved into the rock, about 5   ft to 5   ft 9   in (1.5 to 1.75   m);

5700-416: The habit of condemning well-born citizens to work on the roads. Under the rule of Claudius, Corbulo was brought to justice and forced to repay the money which had been extorted from his victims. Special curatores for a term seem to have been appointed on occasion, even after the institution of the permanent magistrates bearing that title. The emperors who succeeded Augustus exercised a vigilant control over

5800-483: The heading of viae privatae were also included roads leading from the public or high roads to particular estates or settlements; Ulpian considers these to be public roads. Features off the via were connected to the via by viae rusticae , or secondary roads. Both main or secondary roads might either be paved or left unpaved with a gravel surface, as they were in North Africa. These prepared but unpaved roads were viae glareae or sternendae ("to be strewn"). Beyond

The excavation was called the fossa , the Latin word for ditch. The depth varied according to terrain. The method varied according to geographic locality, materials available, and terrain, but the plan or ideal at which the engineer aimed was always the same. The road

Like in the Obersee, the flow the Rhine can be traced in the Untersee. Here, too, the river water is hardly mixed with the lake water. The northern parts of the Untersee (Lake Zell and Gnadensee) remain virtually unaffected by the flow. The river traverses the southern, which, in isolation,

Many local fields have an official name containing this element. A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to

Some of the common, earlier designs incorporated arches . Roman road builders aimed at

The High Rhine ( Hochrhein ) begins in Stein am Rhein at the western end of the Untersee. Now flowing generally westwards, it passes over the Rhine Falls ( Rheinfall ) below Schaffhausen before being joined – near Koblenz in the canton of Aargau  – by its major tributary,

6700-491: The office of curator of each of the great public roads a perpetual magistracy rather than a temporary commission. The persons appointed under the new system were of senatorial or equestrian rank, depending on the relative importance of the roads assigned to them. It was the duty of each curator to issue contracts for the maintenance of his road and to see that the contractor who undertook said work performed it faithfully, as to both quantity and quality. Augustus also authorized

The Alpine Rhine begins in the westernmost part of the Swiss canton of Graubünden , and later forms the border between Switzerland to the west and Liechtenstein and later Austria to the east.

The Tables command Romans to build public roads and give wayfarers the right to pass over private land where the road is in disrepair. Building roads that would not need frequent repair therefore became an ideological objective, as well as building them as straight as practicable to construct

7100-413: The paving of the streets of Rome or at least shared that responsibility with the quattuorviri viarum . It has been suggested that the quaestors were obliged to buy their right to an official career by personal outlay on the streets. There was certainly no lack of precedents for this enforced liberality, and the change made by Claudius may have been a mere change in the nature of the expenditure imposed on

7200-627: The quaestors. The official bodies which first succeeded the censors in the care of the streets and roads were: Both these bodies were probably of ancient origin. The first mention of either body occurs in the Lex Julia Municipalis in 45 BC. The quattuorviri were afterwards called quattuorviri viarum curandarum . The extent of jurisdiction of the duoviri is derived from their full title as duoviri viis extra propiusve urbem Romam passus mille purgandis . Their authority extended over all roads between their respective gates of issue in

The quattuorviri board was kept as it was until at least the reign of Hadrian (117 to 138 AD). Furthermore, he appointed praetorians to the offices of "road-maker" and assigning each one with two lictors , making

Tabula Traiana memorial plaque in Serbia is all that remains of the now-submerged road. Roman bridges were some of the first large and lasting bridges created. River crossings were achieved by bridges, or pontes . Single slabs went over rills. A bridge could be of wood, stone, or both. Wooden bridges were constructed on pilings sunk into

7500-457: The river could experience a massive decrease in volume, or even dry up completely in case of drought, within the next 30 to 80 years, as a result of the climate crisis . The Rhine is the second-longest river in Central and Western Europe (after the Danube ), at about 1,230 km (760 mi), with an average discharge of about 2,900 m /s (100,000 cu ft/s). The Rhine and

7600-545: The river, North Rhine-Westphalia and Rhineland-Palatinate , in addition to several districts (e.g. Rhein-Sieg ). The departments of Bas-Rhin and Haut-Rhin in Alsace (France) are also named after the river. Some adjacent towns are named after it, such as Rheinau , Rheineck , Rheinfelden (CH) and Rheinfelden (D). The International Commission for the Hydrology of the Rhine Basin (CHR) and EUWID contend that

7700-407: The river, or on stone piers. Stone arch bridges were used on larger or more permanent crossings. Most bridges also used concrete, which the Romans were the first to use for bridges. Roman bridges were so well constructed that many remain in use today. Causeways were built over marshy ground. The road was first marked out with pilings. Between them were sunk large quantities of stone so as to raise

7800-464: The roads outside the city, and for forming raised footpaths at the sides. In these roads, the surface was hardened with gravel, and although pavements were introduced shortly afterwards, the blocks were laid on a bed of small stones. Examples include the Via Praenestina and Via Latina . The best sources of information as regards the construction of a regulation via munita are: After

7900-462: The secondary roads were the viae terrenae , "dirt roads". The third category comprised roads at or in villages, districts , or crossroads , leading through or towards a vicus or village. Such roads ran either into a high road or into other viae vicinales , without any direct communication with a high road. They were considered public or private, according to the fact of their original construction out of public or private funds or materials. Such

8000-445: The shortest possible roads, and thus save on material. Roman law defined the right to use a road as a servitus , or liability. The ius eundi ("right of going") established a claim to use an iter , or footpath, across private land; the ius agendi ("right of driving"), an actus , or carriage track. A via combined both types of servitutes , provided it was of the proper width, which was determined by an arbiter . The default width

8100-673: The south to the Flüela Pass in the east. The Rhine is one of four major rivers taking their source in the Gotthard region, along with the Ticino (drainage basin of the Po ), Rhône and Reuss (Rhine basin). The Witenwasserenstock is the triple watershed between the Rhine, Rhône and Po. Traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of

8200-430: The street inside Rome, including the Clivus Capitolinus , with lava, and for laying down the roads outside the city with gravel. Sidewalks were also provided. The aediles , probably by virtue of their responsibility for the freedom of traffic and policing the streets, co-operated with the censors and the bodies that succeeded them. It would seem that in the reign of Claudius the quaestors had become responsible for

8300-412: The surface and at first does not mix with the warmer, green waters of Upper Lake. But then, at the so-called Rheinbrech , the Rhine water abruptly falls into the depths because of the greater density of cold water. The flow reappears on the surface at the northern (German) shore of the lake, off the island of Lindau . The water then follows the northern shore until Hagnau am Bodensee . A small fraction of

8400-483: The surfaces) of many Roman roads survived for millennia; some are overlaid by modern roads. "The extraordinary greatness of the Roman Empire manifests itself above all in three things: the aqueducts, the paved roads, and the construction of the drains." Dionysius of Halicarnassus , Ant. Rom. 3.67.5 Livy mentions some of the most familiar roads near Rome, and the milestones on them, at times long before

8500-617: The term viae regales compare the roads of the Persian kings (who probably organized the first system of public roads) and the King's Highway . With the term viae militariae compare the Icknield Way ( Icen-hilde-weg , or "War-way of the Iceni"). There were many other people, besides special officials, who from time to time and for a variety of reasons sought to connect their names with

8600-535: The terms via munita and vía publica became identical. Viae were distinguished according to their public or private character, as well as according to the materials employed and the methods followed in their construction. Ulpian divided them up in the following fashion: According to Isidore of Sevilla , the Romans borrowed the knowledge of construction of viae munitae from the Carthaginians , though certainly inheriting some construction techniques from

8700-567: The three valleys named Rheinwald , Schams and Domleschg - Heinzenberg . The valleys are separated by the Rofla Gorge and Viamala Gorge. Its sources are located in the Adula Alps ( Rheinwaldhorn , Rheinquellhorn , and Güferhorn ). The Avers Rhine joins from the south. One of its headwaters, the Reno di Lei (stowed in the Lago di Lei ), is partially located in Italy. Near Sils

8800-499: The upper Surselva and flows in an easterly direction. One source is Lai da Tuma (2,345 m (7,694 ft)) with the Rein da Tuma , which is usually indicated as source of the Rhine, flowing through it. Into it flow tributaries from the south, some longer, some equal in length, such as the Rein da Medel , the Rein da Maighels , and the Rein da Curnera . The Cadlimo Valley in

8900-413: The urban administration, both abolished and created new offices in connection with the maintenance of public works, streets, and aqueducts in and around Rome. The task of maintaining the roads had previously been administered by two groups of minor magistrates, the quattuorviri (a board of four magistrates to oversee the roads inside the city) and the duoviri (a board of two to oversee the roads outside

9000-474: The various functionaries, including emperors, who succeeded the censors in this portion of their duties, may be said to have exercised a devolved censorial jurisdiction. The devolution to the censorial jurisdictions became a practical necessity, resulting from the growth of the Roman dominions and the diverse labors which detained the censors in the capital city. Certain ad hoc official bodies successively acted as constructing and repairing authorities. In Italy,

9100-609: The water would flow out from between the stones and fragments of rubble instead of becoming mud in clay soils. According to Ulpian , there were three types of roads: The first type of road included public high or main roads, constructed and maintained at the public expense, and with their soil vested in the state. Such roads led either to the sea, to a town, to a public river (one with a constant flow), or to another public road. Siculus Flaccus , who lived under Trajan (98–117), calls them viae publicae regalesque , and describes their characteristics as follows: Roman roads were named after

9200-403: The years the Romans realized this and built longer but more manageable alternatives to existing roads. Roman roads generally went straight up and down hills, rather than in a serpentine pattern of switchbacks. As to the standard Imperial terminology that was used, the words were localized for different elements used in construction and varied from region to region. Also, in the course of time,

9300-485: Was Julius Caesar , who became curator (67 BC) of the Via Appia and spent his own money liberally upon it. Certain persons appear also to have acted alone and taken responsibility for certain roads. In the country districts, the magistri pagorum had authority to maintain the viae vicinales . In Rome each householder was legally responsible for the repairs to that portion of the street which passed his own house; it

9400-467: Was a military responsibility and thus came under the jurisdiction of a consul. The process had a military name, viam munire , as though the via were a fortification. Municipalities, however, were responsible for their own roads, which the Romans called viae vicinales . Roads were not free to use; tolls abounded, especially at bridges. Often they were collected at the city gate. Freight costs were made heavier still by import and export taxes. These were only

9500-448: Was constructed by filling the fossa . This was done by layering rock over other stones. Into the fossa was placed large amounts of rubble , gravel and stone, whatever fill was available. Sometimes a layer of sand was put down, if it was locally avbailable. When the layers came to within 1 yd (1 m) or so of the surface, the subsurface was covered with gravel and tamped down, a process called pavire , or pavimentare . The flat surface

9600-468: Was dug. It was made navigable to the Swiss town of Rheineck . Lake Constance consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein ("Lake Rhine"). The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg ,

9700-504: Was the latitudo legitima of 8 feet. Roman law and tradition forbade the use of vehicles in urban areas, except in certain cases. Married women and government officials on business could ride. The Lex Julia Municipalis restricted commercial carts to night-time access in the city within the walls and within a mile outside the walls. Roman roads varied from simple corduroy roads to paved roads using deep roadbeds of tamped rubble as an underlying layer to ensure that they kept dry, as

9800-422: Was the duty of the aediles to enforce this responsibility. The portion of any street which passed a temple or public building was repaired by the aediles at the public expense. When a street passed between a public building or temple and a private house, the public treasury and the private owner shared the expense equally. The governing structure was changed by Augustus , who in the course of his reconstitution of

9900-400: Was then the pavimentum . It could be used as the road, or additional layers could be constructed. A statumen or "foundation" of flat stones set in cement might support the additional layers. The final steps utilized lime-based mortar , which the Romans had discovered. They seem to have mixed the mortar and the stones in the ditch. First a small layer of coarse concrete , the rudus , then

10000-465: Was variously inflected as masculine or feminine; and its Old Icelandic adoption was inflected as feminine. The length of the Rhine is conventionally measured in "Rhine-kilometers" ( Rheinkilometer ), a scale introduced in 1939 which runs from the 0 km datum at Old Rhine Bridge in the city of Konstanz , at the western end of Lake Constance , to the Hook of Holland at 1,036.20 km.
