A median strip , central reservation , roadway median , or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways , dual carriageways , freeways, and motorways . The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved , but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping , trees , a median barrier , or railway , rapid transit , light rail , or streetcar lines.
80-589: The 1,227-metre (4,026 ft) Kotezi Viaduct is part of the A1 motorway in Croatia, located between Ravča and Vrgorac interchanges. It is the second-longest viaduct found along the motorway. Construction and opening of the motorway section and the Kotezi Viaduct was marked by a naming dispute, causing the viaduct to be renamed twice in the month before the opening. The local population expressed concerns about
160-512: A hotel or a motel ; B-type rest areas have no lodging; C-type rest areas are very common and include a filling station and a café, but no restaurants or accommodation; D-type rest areas offer parking spaces only, possibly some picnicking tables and benches and restrooms. Even though the rest areas found along the A1 motorway generally follow this ranking system, there are considerable variations as some of them offer extra services. The most notable example
240-623: A large number of tourist destinations such as Bjelolasica in Gorski Kotar , a large number of Adriatic Sea resorts and several national parks and nature parks . In Lika region those are Plitvice Lakes National Park , Sjeverni Velebit National Park and Velebit Nature Park, while in Dalmatia the motorway serves Paklenica National Park, Telašćica Nature Park, Kornati National Park, Lake Vrana Nature Park, Krka National Park and Biokovo Nature Park. The route also provides links to
320-628: A number of UNESCO World Heritage Sites such as Plitvice Lakes , Šibenik Cathedral of St James, Palace of Diocletian in Split and the Historic City of Trogir . The A1 is a tolled motorway based on the vehicle classification in Croatia using a closed toll system integrated with the A6 motorway as the two connect in the Bosiljevo ;2 interchange forming a unified toll system. Since
400-633: A part of the Ravča– Vrgorac section is the Kotezi Viaduct at 1,214 meters (3,983 ft), surpassing all other viaducts on the route except for Drežnik Viaduct. A dispute concerning naming of the Viaduct arose one month prior to opening of the motorway section containing the viaduct, and the structure was even signposted as the Bunina Viaduct for several days in June 2011, only to revert the name to
480-475: A public exchanges or arguments which name should be finally applied. Days after opening of the A1 motorway section containing the viaduct, traffic signs bearing name of the viaduct were vandalized, and newspapers speculated that the event represented a continuation of the naming dispute. Construction of the viaduct caused concern amongst the local population that an embankment used as a temporary structure during construction works would prevent drainage of water from
560-455: A route from Zagreb to Bihać ( Bosnia and Herzegovina ) and then to Split via Knin . The government of Bosnia and Herzegovina issued its approval for the route in Bihać region in the same year. Construction of the motorway was initiated by a fundraising effort — a public loan. The funds gathered initially through the public loan were sufficient for construction of 20 kilometers (12 mi) of
640-457: A route in Neum area to connect Ploče and Dubrovnik while serving Neum. That entails branching of the A1 motorway 7 to 8 kilometres (4.3 to 5.0 miles) west of Neum, one branch serving Neum and the other Dubrovnik. As of July 2012 no decision was reached on the section of the A1 route. A planned modification of the existing route encompasses construction of a directional T interchange to replace
720-719: A section of the M6 between Shap and Tebay, which allows a local road to run between them, and on the M62 where the highest section through the Pennines famously splits wide enough to contain a farm . The other major exception is the A38(M) Aston Expressway , which is a single carriageway of seven lanes, where the median lane moves to account for traffic flow (a system known as tidal flow or reversible lane ). With effect from January 2005 and based primarily on safety grounds,
800-617: A single kingdom in 925. The funds raised through the public loan were left unused for several months, then spent for construction of a road between Vrlika and Strmica via Knin, now a part of the D1 and D30 state roads. However, the United Nations Economic Commission for Europe recognized the route as the southernmost part of the Pyhrn route , giving it the designation E59 in 1975. Subsequent reorganizations of
880-491: A single set of double yellow lines which may in some cases permit turns across the line. This arrangement has been used to reduce costs, including narrower medians than are feasible with a planted strip, but research indicates that such narrow medians may have minimal safety benefit compared to no median at all. The medians of United States Interstate Highways break only for emergency service lanes, with no such restrictions on lower classification roads. On British motorways ,
SECTION 10
#1732794496973960-480: A traffic-calming or landscaping element rather than a safety enhancement to restrict turns and separate opposite directions of high-volume traffic flow. In some areas such as California , highway medians are sometimes no more than a demarcated section of the paved roadway, indicated by a space between two sets of double yellow lines . Such a double-double yellow line or painted median is legally similar to an island median: vehicles are not permitted to cross it, unlike
1040-443: Is Drežnik Viaduct where there are no emergency lanes. Almost all of the existing interchanges are trumpet interchanges , except for Lučko which is a stack . There are numerous rest areas along the motorway, providing various types of services ranging from simple parking spaces and restrooms to petrol stations, restaurants and hotels. As of 2011 , the motorway has 33 interchanges, providing access to numerous towns and cities and
1120-413: Is Krka rest area—even though it has no filling station, there is, for instance, a restaurant available. The filling stations regularly have small convenience stores and some of them offer LPG fuel . EuroTest, an international association of 18 European automobile clubs spearheaded by German automobile club ADAC , surveyed three of the A1 motorway rest areas in 2009: Krka, Lički Osik and Modruš (in case of
1200-581: Is a major north–south motorway in Croatia connecting the capital of the country, Zagreb , to the Dalmatia region, where the motorway follows a route parallel to the Adriatic coast. As a part of the road network of Croatia , it is a part of two major European routes : E65 Prague – Bratislava –Zagreb– Rijeka – Split – Dubrovnik and E71 Budapest –Zagreb– Karlovac – Bihać – Knin –Split. The motorway
1280-587: Is at a premium, dense hedges of shrubs filter the headlights of oncoming traffic and provide a resilient barrier. In other areas, the median may be occupied by a right-of-way for a public transportation system such as a light rail or rapid transit line; for example, the Red and Blue Lines of the Chicago 'L' partially run in the medians of the Dan Ryan , Eisenhower , and Kennedy Expressways . In contrast to
1360-410: Is considered that the true reason for the cancellation of the works was that the motorway was considered to be a "nationalist" project. The conclusion is supported by the fact the road was spontaneously nicknamed King Tomislav Motorway ( Croatian : Autocesta kralja Tomislava ) by citizens investing their money through the public loan after the first king of medieval Croatia , who united Croatia as
1440-656: Is less confusing to call these central lanes the "passing", "fast", or "overtaking" lanes in international contexts, instead of using the ambiguous inner/outer distinction. Regional differences between right-hand traffic and left-hand traffic can cause further confusion. Some medians function secondarily as green areas and green belts to beautify roadways . Jurisdictions can: plant lawn grasses with regular mowing ; hydroseed or scatter wildflower seeds to germinate , bloom, and re-seed themselves annually; or create extensive landscape plantings of trees , shrubs , herbaceous perennials and ornamental grasses . Where space

This 502-bed facility was opened in 1993 as infill construction in the previously unused real estate that had been isolated by the divided highway in the early 1950s. An extreme example of a wide median can be found on Interstate 75 near Cincinnati , Ohio ; nearly the entire village of Arlington Heights , as well as the downtown district of Lockland , are both located between
1600-761: Is no international English standard for the term. Median , median strip , and median divider island are common in North American and Antipodean English . Variants in North American English include regional terms such as neutral ground in New Orleans usage. In British English the central reservation or central median is the preferred usage; it also occurs widely in formal documents in some non-British regions such as South Africa, where there are other informal regional words (for example middelmannetjie , which originally referred to
1680-466: Is of major importance to Croatia in terms of development of the economy ; especially tourism and as a transit transport route. This has been reflected by an accelerated development of regions connected by the A1 motorway. A part of the motorway is considered to be a segment of the Adriatic–Ionian motorway . Once the latter motorway's connecting sections are completed, those currently spanned just by

South of the Bosiljevo 2 interchange the first major drop of traffic volume is recorded on the A1 motorway, due to traffic transferring to the A6 motorway towards Rijeka. Other similar changes of
1840-419: Is regularly counted by means of traffic census at toll stations and reported by Autocesta Rijeka–Zagreb and Hrvatske autoceste—the operators of the northern and the southern portions of the motorway respectively. The reported traffic volume gradually decreases as the motorway chainage increases and as it passes by various major destinations and the interchanges that serve them. Thus the greatest volume of traffic
1920-502: Is shared at all motorways in Croatia (except the A2 motorway ) and provides drivers use of dedicated lanes at toll plazas and a discounted toll rates. The A1 north of the Bosiljevo 2 interchange is operated by Autocesta Rijeka — Zagreb and the rest is operated by Hrvatske autoceste, both of which do not report company toll income separately for individual sections of various motorways. Total toll income reported by Hrvatske autoceste in

Statistics regarding medians with barriers were not calculated in this study. Central reservations may also be used for reserved bus lanes , as in Istanbul's Metrobus , Los Angeles's J Line and Bogotá's TransMilenio . Center-lane running and island platforms installed in
2080-603: Is the second-longest viaduct along the A1 motorway route, surpassed only by the Drežnik Viaduct . The viaduct was built by a joint venture of DYWIDAG and Strabag but 320 prestressed beams were built in Viadukt Zagreb TBP Pojatno, and it represents the most complex structure along the Ravča–Vrgorac section of the A1 motorway. Construction of the viaduct was accompanied by a naming dispute. Originally

The motorway spans 476.3 kilometers (296.0 mi) between Zagreb ( Lučko interchange ) and Ploče via Split. The route serves Karlovac via D1 , Gospić via D534 , Zadar via D8 and D424 and Šibenik via D533 . The A1 motorway consists of two traffic lanes and an emergency lane in each driving direction along its entire length. The sole exception

2560-595: The 1970s and in the 2000s, construction of the Zagreb–Split motorway was perceived to symbolize rebuilding of national unity. The Zagreb–Split motorway, now the A1 motorway, was one of three routes defined by the Parliament of the Socialist Republic of Croatia on 5 March 1971, as priority transport routes of Croatia that were to be developed as motorways. Originally the motorway was designed to follow
2640-487: The 2000s, as the motorway construction works were gradually progressing further south, the motorway earned its unofficial, yet widely used name— Dalmatina in Croatian press because it connected Zagreb to Dalmatia . In 2010, Donja Zdenčina interchange was opened between Lučko and Jastrebarsko interchanges, and in June 2012, Novigrad interchange opened bringing number of motorway exits to 33. The construction cost for

The most notable among them are: the 5,821-meter (19,098 ft) long Mala Kapela Tunnel between Ogulin and Brinje interchanges and the 5,768-meter (18,924 ft) long Sveti Rok Tunnel between Sveti Rok and Maslenica interchanges. The Mala Kapela and Sveti Rok tunnels are not only the largest individual structures on the motorway but they are also the longest tunnels in Croatia. The tunnels separate three distinct climate zones. The Mala Kapela Tunnel spans between
2880-490: The A1 section represents the busiest section of the motorway network operated by Autocesta Rijeka — Zagreb. Hrvatske autoceste and Autocesta Rijeka — Zagreb reported increase of the toll income compared to the same period of 2010 of 2.2% and 5% respectively. Summertime and holiday queues at Lučko mainline toll plaza can be considerable, a problem exacerbated during the usual weekend-to-weekend tourist stays at Croatia's coastal resorts. In 2009, in an effort to address
2960-416: The Bosiljevo 2–Split (Dugopolje interchange) sector of the motorway was originally estimated by the government in 2001 and presented as "3 × 3 x 3" – that is, the 300 kilometers (190 mi) of the motorway was to be completed in 3 years at a cost of 3 billion marks (approximately 12.65 billion kuna at the time, or approximately 1.533 billion euros). In 2010, Hrvatske autoceste reported that
3040-484: The Bunina Polje spanned by the viaduct. The polje is regularly flooded each winter and spring due to high precipitation. Additional concerns were raised that the construction works may cause reduced yield of Betina spring and lack of flooding as was the case in 2008, when two adjacent poljes, Rastok and Jezero, were flooded unlike the Bunina Polje; any shortage of water presents a concern for agricultural production in
3120-584: The E-road network, including the latest one in 2008, transferred the route south of Zagreb to the E71. In the beginning of the 1990s, construction of the motorway was further postponed because of onset of the Croatian War of Independence . The decade saw renewed discussion regarding construction of the motorway, including renewed considerations of its route. Soon, the originally devised route running through Bihać

After suppression of the Croatian Spring and removal of the Croatian leadership that proposed and adopted the construction plan in 1971, all
3280-787: The UK's Highways Agency 's policy is that all new motorway schemes are to use high containment concrete step barriers in the median (central reservation). All existing motorways will introduce concrete barriers as part of ongoing upgrades and through replacement as and when the current systems have reached the end of their useful life. This change of policy applies only to barriers in the median of high speed roads and not to verge side barriers. Other routes will continue to use steel barriers. In North America , and some other countries with large sparsely populated areas, opposing lanes of traffic may be separated by several hundred meters of fields or forests outside of heavily populated areas (an extreme example being

3360-535: The US Federal Highway Administration quantified the correlation between median width and the reduction of both head-on accidents and severe injuries. The study found that medians without barriers should be constructed more than 30 feet (9.1 m) wide in order to have any effect on safety, and that safety benefits of wider medians continue to increase to a width of 60 to 80 feet (18.3 to 24.4 m). A consequence of this finding

Construction cost incurred on the Dugopolje–Ploče sector of the motorway between 2005 and 2008 was reported at 4.1 billion kuna and additional 1.8 billion kuna of construction expenses are planned until
3600-542: The carriageways may have to be built on different levels of the slope. An example of this is on the M5 motorway as it climbs up the side of the Gordano Valley south of Bristol . In Birmingham and many other cities, suburban dual carriageways may have trees or cycle lanes in the middle as a wide central reservation. Two examples on the UK road network where the carriageways are several hundred yards/metres apart, are on

It shall not feature any weaving , similar to the Bosiljevo 2 interchange of the A1 and A6 motorways. The tendering of two segments began in January 2024, 20.5 kilometers between Rudine - Mravinjac. The design started three stages 7.5 kilometers between Mravinjac - Osojnik. Traffic
3840-496: The first half of 2011 was 508.1 million kuna (68.3 million euro). This figure pertains to the A1 south of the Bosiljevo 2 interchange as well as all other motorways operated by Hrvatske autoceste, however the A1 represents the longest and the busiest tolled motorway operated by Hrvatske autoceste. Toll income reported by Autocesta Rijeka — Zagreb for the first half of 2011 is 191.2 million kuna (25.7 million euro). This sum includes company toll income generated elsewhere, however
3920-600: The first sections not shared with the Zagreb–Rijeka Motorway were completed: Vukova Gorica–Mala Kapela Tunnel and Gornja Ploča–Zadar 2. Mala Kapela Tunnel–Gornja Ploča, Zadar 2–Pirovac and Vrpolje–Dugopolje sections opened in 2004 and Mala Kapela Tunnel itself and Pirovac–Vrpolje section opened in 2005 marking completion of the Zagreb–Split Motorway, culminating with the grand opening of Karlovac — Split section on 26 June 2005.

In their simplest form, these are just raised concrete curbs, but can also be landscaped with grass or trees or decorated with bricks or stones. Such medians are also sometimes found on more minor or residential streets, where they serve primarily as
4480-470: The medium reduce conflicts with stopped and parked cars as well as pedestrians near the curb, thus speeding service. In some cases, the median strip of the highway may contain a train line, usually around major urban centers. This is often done to share a right-of-way , because of the expense and difficulty of clearing a route through dense urban neighborhoods. A reserved right-of-way is contrasted with street running , in which rail cars and automobiles occupy

While the construction of the Pelješac Bridge , spanning the coast south of Ploče and the Pelješac peninsula, had been associated with A1, its design includes only one traffic lane in each direction unlike the A1 motorway standard of two. In April 2012, government of Bosnia-Herzegovina proposed
5600-451: The same ministry updated the document with a definition of the A1 ending with "Opuzen – Zavala (border of Croatia and Bosnia and Herzegovina) – Imotica (ditto border) – Dubrovnik". Hrvatske autoceste, operator of the southern portion of the A1 motorway, ordered the execution of design documents, feasibility and environmental impact studies for the Doli – Osojnik section of the motorway that
5680-555: The shore of the Adriatic Sea , the motorway represents a major north–south transportation corridor in Croatia and a significant part of the Adriatic–Ionian motorway . Apart from Zagreb and Split, the A1 motorway runs near a number of major Croatian cities , provides access to several national parks or nature parks , world heritage sites , and numerous resorts, especially along the Adriatic Coast . National significance of
5760-427: The structure was named Kotezi Viaduct, after the nearest toponym , village of Kotezi, only to be changed to Bunina Viaduct less than a month before its opening to traffic. However, only days after the decision was publicized by newspapers, Hrvatske autoceste decided to revert to the original name following protests by residents of Kotezi village. The latest change was contested by residents of Bunina village, leading to
5840-413: The tolled motorway network, as the ultimate solution for congestion at the Lučko toll plaza. That will require construction of a Horvati interchange south of the Lučko toll plaza. A total of 361 structures—bridges, viaducts, flyovers, underpasses, passages, wildlife crossings , and tunnels—have been completed on the motorway between Zagreb and Vrgorac, and calculations indicate that 18.6 percent of
5920-486: The traffic volume are registered near Zadar (served by Zadar 1 and Zadar 2 interchanges) and Split served by Dugopolje interchange. Substantial variations observed between AADT and ASDT are normally attributed to the fact that the motorway carries significant tourist traffic. The seasonal increase traffic volume variations ranges 69% on the busiest, Lučko–Jastrebarsko section to 160% as measured on Sveti Rok–Maslenica section. The summer season traffic volume increase on
6000-712: The two directions of I-75. Some freeways in North America include "inverted" medians, which separate roadways running in the opposite direction from the standard for the country they are located in. Roads are so designed for a number of reasons, including to save space, for the creation of continuous flow intersections , or for diverging diamond interchanges . Inverted medians are also used in rare cases on local streets that historically had unusual traffic patterns, such as Bainbridge Street between 3rd Street and 5th Street in Philadelphia . An August 1993 study by
6080-542: The two longest tunnels in Croatia and two bridges comprising spans of 200 meters (660 ft) or more. There are 33 exits and 26 rest areas operating along the route. As the motorway is tolled using a ticket system and vehicle classification in Croatia , each exit includes a toll plaza. A motorway connecting Zagreb and Split was designed in the early 1970s, and a public loan was started in order to collect sufficient funds for its construction. However, due to political upheavals in Croatia and Yugoslavia , construction of
6160-415: The two motorways are operated by Autocesta Rijeka — Zagreb and Hrvatske autoceste, the toll collection system is operated jointly by the two operators. The toll is payable in Croatian kuna , euro, major credit and debit cards and using a number of prepaid toll collection systems including various types of smart cards issued by the motorway operators and ENC – an electronic toll collection (ETC) which
6240-515: The viaduct's effects on the drainage of floodwater from the karst polje it spans and on groundwater levels in the area. The Kotezi Viaduct is a reinforced concrete viaduct carrying the A1 motorway in Croatia between Ravča and Vrgorac, across the Bunina Polje . It is 1,227 metres (4,026 ft) long and 28 metres (92 ft) wide, built as a dual structure, each part carrying two traffic lanes and an emergency lane . The Kotezi Viaduct
6320-419: The work related to the Zagreb–Split motorway was cancelled. The plans were revived in the 1990s and new designs were developed to include a motorway section built between Zagreb and Karlovac into the design so that the section could be shared between Zagreb–Split and Zagreb–Rijeka motorways. Construction work started in 2000 and the motorway reached Split by 2005 and was extended towards Dubrovnik later on. Both in
6400-543: Was set aside and two new routes were considered: One of them was a modified version of the original route, bypassing Bihać and running through the Plitvice Lakes region while the other was a completely new route further to the west via Gospić and Zadar, which was eventually accepted for construction. Both of the alternative routes proposed that the Zagreb–Karlovac motorway already completed in 1972 were to be used as
