110-474: The Hammonasset Connector is a 1.35-mile-long (2.17 km) freeway from Interstate 95 (I-95) to U.S. Route 1 (US 1). The Hammonasset Connector begins as a continuation of Duck Hole Road at exit 62 on I-95 in the town of Madison . The connector is designated as part of Special Service Road 450 ( SSR 450 ), a designation which continues along Duck Hole Road and Horse Pond Road to Route 79 . The road gets its name from Hammonasset State Park ,
220-663: A dual highway ) in 1932 between Cologne and Bonn . It then rapidly constructed the first nationwide system of such roads. The first North American freeways (known as parkways) opened in the New York City area in the 1920s. Britain, heavily influenced by the railways, did not build its first motorway , the Preston By-pass ( M6 ), until 1958. Most technologically advanced nations feature an extensive network of freeways or motorways to provide high-capacity urban travel, or high-speed rural travel, or both. Many have
330-466: A median separates the opposite directions of traffic. This strip may be as simple as a grassy area, or may include a crash barrier such as a " Jersey barrier " or an "Ontario Tall Wall" to prevent head-on collisions . On some freeways, the two carriageways are built on different alignments; this may be done to make use of available corridors in a mountainous area or to provide narrower corridors through dense urban areas . Control of access relates to
440-581: A military jail . Among the legions stationed in Bonn, the "1st", i.e. the Prima Legio Minervia , seems to have served here the longest. Units of the Bonn legion were deployed to theatres of war ranging from modern-day Algeria to what is now the Russian republic of Chechnya . The chief Roman road linking the provincial capitals of Cologne and Mainz cut right through the fort where it joined
550-561: A class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention , the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals , intersections or property access . They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses . Entrances and exits to
660-707: A cloverleaf and trumpet interchange when it opened in 1937, and until the Second World War , boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since gone on to become the busiest highway in the world. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have
770-620: A freeway, specialized pedestrian footbridges or tunnels may also be provided. These structures enable pedestrians and cyclists to cross the freeway at that point without a detour to the nearest road crossing. Access to freeways is typically provided only at grade-separated interchanges , though lower-standard right-in/right-out (left-in/left-out in countries that drive on the left) access can be used for direct connections to side roads. In many cases, sophisticated interchanges allow for smooth, uninterrupted transitions between intersecting freeways and busy arterial roads . However, sometimes it
880-434: A larger number of guide signs than other roads, and the signs themselves are physically larger. Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on
990-499: A legal status which limits the types of vehicles that can use a highway, as well as a road design that limits the points at which they can access it. Major arterial roads will often have partial access control , meaning that side roads will intersect the main road at grade, instead of using interchanges, but driveways may not connect directly to the main road, and drivers must use intersecting roads to access adjacent land. At arterial junctions with relatively quiet side roads, traffic
1100-467: A local road. The Hammonasset Connector was built in 1957, serving as a freeway from I-95 to the park in Madison. The Connecticut Department of Transportation (CDOT) had once planned to turn the southern terminus of the connector into an interchange, where ramps would be given for US 1 and the connector's internal designation, 450, would continue in the park. In fact, the designation did stretch into
1210-527: A milepost system but does not use milepost markers. In Europe and some other countries, motorways typically have similar characteristics such as: Two-lane freeways , often undivided, are sometimes built when traffic volumes are low or right-of-way is limited; they may be designed for easy conversion to one side of a four-lane freeway. (For example, most of the Bert T. Combs Mountain Parkway in eastern Kentucky

#17327810618091320-447: A motorway is understood as a public road with dual carriageways and at least two lanes each way. All entrances and exits are signposted and all interchanges are grade separated. Central barrier or median present throughout the road. No crossing is permitted, while stopping is permitted only in an emergency. Restricted access to motor vehicles, prohibited to pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The minimum speed
1430-777: A national-level or even international-level (e.g. European E route ) system of route numbering . There are several international standards that give some definitions of words such as motorways, but there is no formal definition of the English language words such as freeway , motorway , and expressway , or of the equivalent words in other languages such as autoroute , Autobahn , autostrada , autocesta, autoput , that are accepted worldwide—in most cases these words are defined by local statute or design standards or regional international treaties. Descriptions that are widely used include: One green or blue symbol (like [REDACTED] ) appears at motorway entry in countries that follow
1540-600: A number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type of road, etc. In some jurisdictions feeder/distributor lanes are common, especially for cloverleaf interchanges ; in others, such as the United Kingdom, where the roundabout interchange is common, feeder/distributor lanes are seldom seen. Motorways in Europe typically differ between exits and junctions. An exit leads out of
1650-624: A park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of the Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then
1760-457: A private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by the federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in
1870-609: A reduction in deaths in a range from 20% to 50% on those sections. Speed, in Europe, is considered to be one of the main contributory factors to collisions. Some countries, such as France and Switzerland, have achieved a death reduction by a better monitoring of speed. Tools used for monitoring speed might be an increase in traffic density; improved speed enforcement and stricter regulation leading to driver license withdrawal; safety cameras; penalty point; and higher fines. Some other countries use automatic time-over-distance cameras (also known as section controls ) to manage speed. Fatigue
1980-541: A separate roadway or altogether eliminates it. In some parts of the world, notably parts of the US , frontage roads form an integral part of the freeway system. These parallel surface roads provide a transition between high-speed "through" traffic and local traffic. Frequent slip-ramps provide access between the freeway and the frontage road, which in turn provides direct access to local roads and businesses. Except on some two-lane freeways (and very rarely on wider freeways),
2090-510: A similar system of express and local lanes for a maximum width of 21 lanes on a 2-mile (3.2 km) segment between Interstate 805 and California State Route 56 . In Mississauga , Ontario, Highway 401 uses collector-express lanes for a total of 18 lanes through its intersection with Highway 403 / Highway 410 and Highway 427 . These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes , either as

2970-735: Is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater interference with traffic are still preferred in North America. There may be occasional interchanges with other major arterial roads. Examples include US 23 between SR 15 's eastern terminus and Delaware, Ohio , along with SR 15 between its eastern terminus and I-75 , US 30 , SR 29 / US 33 , and US 35 in western and central Ohio.

However, due to the enlargement of Bonn in 1969 through the incorporation of Beuel and Bad Godesberg, it moved into the larger Stadthaus facilities further north. This was necessary for the city council to accommodate an increased number of representatives. The mayor of Bonn still sits in
8140-551: The city became part of the German Empire in 1871 during the Prussian-led unification of Germany . Bonn was of little relevance in these years. During the Second World War , Bonn acquired military significance because of its strategic location on the Rhine, which formed a natural barrier to easy penetration into the German heartland from the west. The Allied ground advance into Germany reached Bonn on 7 March 1945, and

To the north, Bonn borders the Cologne Lowland . Natural borders are constituted by the river Sieg to the north-east and by the Siebengebirge (also known as the Seven Hills) to the east. The largest extension of the city in north–south dimensions
8470-494: The city of Bonn is an urban district in its own right. The urban district of Bonn is then again divided into four administrative municipal districts (German: Stadtbezirk ). These are Bonn, Bonn-Bad Godesberg, Bonn-Beuel and Bonn-Hardtberg. In 1969, the independent towns of Bad Godesberg and Beuel as well as several villages were incorporated into Bonn, resulting in a city more than twice as large as before. Bonn has an oceanic climate ( Köppen : Cfb ; Trewartha : Dobk ). In
8580-508: The city of Bonn is the University of Bonn (including the university clinics) and Stadtwerke Bonn also follows as a major employer. On the other hand, there are several traditional, nationally known private companies in Bonn such as luxury food producers Verpoorten and Kessko, the Klais organ manufacture and the Bonn flag factory. The largest confectionery manufacturer in Europe, Haribo , has its founding headquarters (founded in 1920) and
8690-462: The city, there is the Siebengebirge which is part of the lower half of the Middle Rhine region. The nearby upper half of the Middle Rhine from Bingen to Koblenz is a UNESCO World Heritage Site with more than 40 castles and fortresses from the Middle Ages and important German vineyards. Named after Konrad Adenauer , the first post-war Chancellor of West Germany, Cologne Bonn Airport
8800-492: The common European definition, a motorway is defined as "a road, specially designed and built for motor traffic, which does not serve properties bordering on it, and which: (a) is provided, except at special points or temporarily, with separate carriageways for the two directions of traffic, separated from each other, either by a dividing strip not intended for traffic, or exceptionally by other means; (b) does not cross at level with any road, railway or tramway track, or footpath; (c)
8910-517: The early 1920s in response to the rapidly increasing use of the automobile , the demand for faster movement between cities and as a consequence of improvements in paving processes, techniques and materials. These original high-speed roads were referred to as " dual highways " and have been modernized and are still in use today. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"),
9020-485: The first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the A8 and A9 motorways, was devised by Piero Puricelli and was inaugurated in 1924. This motorway, called autostrada , contained only one lane in each direction and no interchanges. The Bronx River Parkway was the first road in North America to utilize a median strip to separate the opposing lanes, to be constructed through
9130-412: The first half of the 20th century. Italy was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. Italy opened its first autostrada in 1924, A8 , connecting Milan to Varese . Germany began to build its first controlled-access autobahn without speed limits (30 kilometres [19 mi] on what is now A555 , then referred to as
9240-647: The fort along with the remnants of the troops stationed here. During the final decades of Imperial rule, the troops were supplied by Franci chieftains employed by the Roman administration. When the end came, these troops simply shifted their allegiances to the new barbarian rulers, the Kingdom of the Franks . From the fort, the Bonnburg, as well as from a new medieval settlement to the South centered around what later became
9350-571: The fort's main road (now, Römerstraße). Once past the South Gate, the Cologne–Mainz road continued along what are now streets named Belderberg, Adenauerallee et al. On both sides of the road, the local settlement, Bonna , grew into a sizeable Roman town. Bonn is shown on the 4th century Peutinger Map . In late antiquity , much of the town seems to have been destroyed by marauding invaders. The remaining civilian population then took refuge inside
9460-675: The headquarters of the Deutsche Post called Post Tower (162.5 m or 533 ft) and the former building for the German members of parliament Langer Eugen (114.7 m or 376 ft) now the location of the UN Campus.

The Haus der Geschichte
9570-504: The highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials and collector roads . On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, while increasing traffic capacity and speed. Controlled-access highways evolved during
9680-484: The last remnants of the medieval city wall. To date, Bonn's Roman fort remains the largest fort of its type known from the ancient world , i.e. a fort built to accommodate a full-strength Imperial Legion and its auxiliaries. The fort covered an area of approximately 250,000 square metres (62 acres). Between its walls it contained a dense grid of streets and a multitude of buildings, ranging from spacious headquarters and large officers' quarters to barracks , stables and
9790-469: The mayor of Cologne . The German Autobahn became the first nationwide highway system. In Canada , the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured
9900-414: The mid-5th century. The structures themselves remained standing well into the Middle Ages , when they were called the Bonnburg. They were used by Frankish kings until they fell into disuse. Eventually, much of the building materials seem to have been re-used in the construction of Bonn's 13th-century city wall . The Sterntor [ de ] ( star gate ) in the city center is a reconstruction using
10010-400: The motorway system, whilst a junction is a crossing between motorways or a split/merge of two motorways. The motorway rules end at exits, but not at junctions. However, on some bridges, motorways, without changing appearance, temporarily end between the two exits closest to the bridge (or tunnel), and continue as dual carriageways . This is in order to give slower vehicles a possibility to use
10120-477: The newly formed Federal Republic of Germany in 1949. However, the Bundestag, seated in Bonn's Bundeshaus , affirmed Berlin 's status as the German capital. Bonn was chosen as the provisional capital and seat of government despite the fact that Frankfurt already had most of the required facilities and using Bonn was estimated to be 95 million DM more expensive than using Frankfurt. Bonn was chosen because Adenauer and other prominent politicians intended to make Berlin
10230-484: The northern sub-district of Graurheindorf, the inland harbour of Bonn is used for container traffic as well as oversea transport. The annual turnover amounts to around 500,000 t (490,000 long tons; 550,000 short tons). Regular passenger transport occurs to Cologne and Düsseldorf. The head offices of Deutsche Telekom , its subsidiary Telekom Deutschland , Deutsche Post , German Academic Exchange Service , and SolarWorld are in Bonn. The third largest employer in
10340-439: The other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than 100 metres (330 ft)). An interchange or a junction is a highway layout that permits traffic from one controlled-access highway to access another and vice versa, whereas an access point is a highway layout where traffic from a distributor or local road can join a controlled-access highway. Some countries, such as
10450-505: The park at the southern terminus of the freeway. The connector starts as a continuation of Duck Hole Road at an interchange with I-95 in Madison. The road crosses over I-95 about 190 yards (170 m) from when it begins. The connector parallels the Hammonasset River for its entire length. The connector terminates at an intersection with U.S. Route 1 in Madison, and the road continues into Hammonasset State Park beyond US 1 as
10560-701: The park until 1984, when it was truncated to US 1. There had also been a plan to build a Route 79 expressway over the connector, but this did not occur. The entire route is in Madison , New Haven County . Controlled-access highway A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway , motorway , and expressway . Other similar terms include throughway or thruway and parkway . Some of these may be limited-access highways , although this term can also refer to
10670-477: The rate is higher than the risk on urban roads. Speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash. According to ETSC, German motorways without a speed limit, but with a 130 km/h (81 mph) speed recommendation, are 25% more deadly than motorways with a speed limit. Germany also introduced some 130 km/h (81 mph) speed limits on various motorway sections that were not limited. This generated
10780-643: The rights of light , air and access to highways, but not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus, as originally conceived, a freeway is simply a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Freeways, by definition, have no at-grade intersections with other roads, railroads or multi-use trails . Therefore, no traffic signals are needed and through traffic on freeways does not normally need to stop at traffic signals. Some countries, such as
10890-525: The seat of government to move to Berlin, others advocated leaving it in Bonn – a situation roughly analogous to that of the Netherlands , where Amsterdam is the capital but The Hague is the seat of government. Berlin's previous history as united Germany's capital was strongly connected with the German Empire , the Weimar Republic and more ominously with both Nazi Germany and Prussia . It
11000-432: The side of a divided highway that has a lot of private access on one side and sometimes has long driveways on the other side since an easement for widening comes into place, especially in rural areas. When a third carriageway is added, sometimes it can shift a directional carriageway by 20–60 metres (50–200 ft) (or maybe more depending on land availability) as a way to retain private access on one side that favors over

11550-406: The year 2010, comparing overall fatality rates with motorway rates (regardless of traffic intensity): The German autobahn network illustrates the safety trade-offs of controlled access highways. The injury crash rate is very low on autobahns, while 22 people died per 1,000 injury crashes—although autobahns have a lower rate than the 29 deaths per 1,000 injury accidents on conventional rural roads,
11660-443: Was European route E4 from Gävle to Axmartavlan , Sweden. The high rate of crashes with severe personal injuries on that (and similar) roads did not cease until a median crash barrier was installed, transforming the fatal crashes into non-fatal crashes. Otherwise, freeways typically have at least two lanes in each direction; some busy ones can have as many as 16 or more lanes in total. In San Diego, California , Interstate 5 has

Additionally, Bonn was closer to Brussels , headquarters of the European Economic Community . Former West German chancellor and mayor of West Berlin Willy Brandt caused considerable offence to the Western Allies during the debate by stating that France would not have kept the seat of government at Vichy after Liberation. The heated debate that resulted
11990-552: Was settled by the Bundestag (Germany's parliament) only on 20 June 1991. By a vote of 338–320, the Bundestag voted to move the seat of government to Berlin. The vote broke largely along regional lines, with legislators from the south and west favouring Bonn and legislators from the north and east voting for Berlin. It also broke along generational lines as well; older legislators with memories of Berlin's past glory favoured Berlin, while younger legislators favoured Bonn. Ultimately,
