The A1 motorway ((クロアチア語:Autocesta A1)) is the longest motorway in Croatia, spanning . As it connects Zagreb, the nation's capital, to Split, the second largest city in the country and the largest city in Dalmatia, 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 the motorway is reflected through its positive economic impact on the cities and towns it connects as well as its importance to tourism in Croatia. The motorway consists of two traffic lanes and an emergency lane in each driving direction separated by a central reservation. All intersections of the A1 motorway are grade separated. As the route traverses rugged mountainous and coastal terrain the route, completed , required 376 bridges, viaducts, tunnels and other similar structures, including the two longest tunnels in Croatia and two bridges comprising spans of 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 the motorway was labeled a "nationalist project" and cancelled in 1971. After Croatian independence and conclusion of the Croatian War of Independence, efforts to build the motorway were renewed and construction started in 2000. The Zagreb–Split section of the route was completed by 2005, while the first sections between Split and Dubrovnik opened in 2007 and 2008. Construction costs incurred so far amount to 3 billion euro. The figure includes funds approved for construction work scheduled to be completed by 2013. On the other hand, the amount does not include construction cost related to Lučko–Bosiljevo 2 section since that section was funded as a part of Rijeka–Zagreb motorway construction project through Autocesta Rijeka–Zagreb, current operator of that sector. The remainder of the A1 motorway, i.e., the sections south of the Bosiljevo 2 interchange are operated by Hrvatske autoceste. == Route description == The A1 motorway ((クロアチア語:Autocesta A1)) 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 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 the Adriatic Highway as well as two-lane roads in Slovenia and Albania, the A1 will achieve genuine importance as a transit route. The motorway spans 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 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.〔(【引用サイトリンク】 url = http://www.hac.hr/files/file/brosure/monografija/virtualMagazine.html )〕〔(【引用サイトリンク】Autocesta Rijeka - Zagreb "> url = http://www.arz.hr/index.php?page=6&sub=2&lng=2 )〕〔(【引用サイトリンク】 url = http://www.hac.hr/en/motorways/rest-areas/ )〕 As of June 2011, the motorway has 33 interchanges, providing access to numerous towns and cities and the Croatian state road network. The ultimate southern terminus of the motorway has been established to be near Dubrovnik. Between the Lučko and Bosiljevo 2 interchanges, the motorway follows Pan-European corridor Vb, and is concurrent with the Zagreb–Rijeka motorway. The Bosiljevo 2 interchange distributes southbound A1 traffic flowing to Rijeka (via the A6 motorway) and to Split. That segment of the motorway is operated by Autocesta Rijeka–Zagreb, while the remainder of the motorway is operated by Hrvatske autoceste.〔(【引用サイトリンク】 url = http://www.hac.hr/en/about-us/mission/ )〕〔(【引用サイトリンク】 url = http://www.huka.hr/Motorways-network/ )〕 An automatic traffic monitoring and guidance system is in place along the motorway. It consists of measuring, control and signaling devices, located in zones where driving conditions may vary—at interchanges, near viaducts, bridges, tunnels, and in zones where fog and strong wind are known to occur. The system comprises variable traffic signs used to communicate changing driving conditions, possible restrictions and other information to motorway users. The motorway route offers a scenic ride through rolling hills in the north, mountains in its central section, and along the Dalmatian coast in the south. It serves, either directly or via connecting roads, a large number of tourist destinations such as Bjelolasica in Gorski Kotar,〔(【引用サイトリンク】 url = http://www.bjelolasica.hr/index.php?page=whereAreWe&l=en )〕 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 a number of UNESCO World Heritage Sites such as Plitvice Lakes, Cathedral of St. James in Šibenik, Palace of Diocletian in Split and the Historic City of Trogir. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A1 (Croatia)」の詳細全文を読む スポンサード リンク
