The A3 motorway ((クロアチア語:Autocesta A3)) is a major motorway in Croatia spanning . The motorway connects Zagreb, the nation's capital, to the Slavonia region and a number of cities along the Sava River. It represents a major east–west transportation corridor in Croatia and a significant part of the Pan-European Corridor X, serving as a transit route between the European Union states and the Balkans. Apart from Zagreb, where the A3 motorway comprises a considerable part of the Zagreb bypass, the motorway runs near a number of significant Croatian cities. The motorway has a positive economic impact on the cities and towns it connects, and is an important route within 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 A3 motorway are grade separated, and the motorway comprises several large stack and cloverleaf interchanges at junctions with four other motorways in Croatia: A1, A2, A4 and A5. As of October 2010, another cloverleaf interchange is under construction on the A3 route, where the A11 motorway is scheduled to branch off. The route comprises a large number of bridges and culverts, but has no tunnels because it runs through plains. The Sava River Bridge is the most significant structure on the A3. Currently, there are 21 exits and 18 rest areas operating along the route. A large part of the motorway is tolled using a ticket system; one section uses an open toll collection system. The Zagreb bypass sections are not tolled. The toll is charged according to vehicle classification in Croatia.〔(【引用サイトリンク】 url = http://www.hac.hr/en/toll-rates/toll-payment-conditions/ )〕 The A3 motorway is operated by Hrvatske autoceste.〔(【引用サイトリンク】 url = http://www.huka.hr/Motorways-network/ )〕 Construction of the six-lane motorway began in 1977, initially as the Zagreb bypass, then continued in the 1980s as an expansion of the existing two-lane road between Zagreb and Belgrade. The construction was suspended in the first part of the 1990s, due to the Croatian War of Independence, and resumed in 1996. Construction of the entire route was completed in 2006; further development entails new exits, new rest areas and the reconstruction of the existing motorway.〔 The construction cost of the A3 motorway is estimated at 7 billion Croatian kuna (approximately 958.9 million euro). ==Route description== The A3 motorway ((クロアチア語:Autocesta A3)) is a major east–west motorway in Croatia connecting the capital of the country, Zagreb, to the Slavonia region, where the motorway follows a route parallel to the Sava River and further on to Serbian and Slovenian motorway networks. As a part of the road network of Croatia, it represents a part of European route E70 Bordeaux–Turin–Ljubljana–Zagreb–Belgrade–Bucharest. The motorway has facilitated accelerated economic development in the regions it connects. The motorway also connects to a number of other motorways in Croatia (from the west to the east): the A2 at the Jankomir interchange, the A1 at Lučko interchange, the A4 at Ivanja Reka and the A5 at the Sredanci interchange. As of October 2010, a junction with the A11 is under construction near Jakuševec. The motorway spans between the Bregana border crossing, located near Samobor, to Slovenia and the Bajakovo border crossing to Serbia, east of Županja. It represents the shortest and the most comfortable transit traffic route between Slovenia, northern Italy, Austria, Switzerland, and southern Germany to the west; and Serbia, Bosnia and Herzegovina, Bulgaria, Macedonia, Greece, and Turkey to the east.〔 The route serves Sisak via the D36; Banja Luka, Bosnia and Herzegovina via the D5 and Stara Gradiška border crossing; Osijek via the A5; and Vinkovci via the D55. The A3 motorway route is complete since no extensions or alterations to the route are planned by applicable legislation.〔 The A3 motorway consists of two traffic lanes and an emergency lane in each driving direction along its entire length. As of September 2010, the motorway has 21 interchanges, providing access to numerous towns and cities and the Croatian state road network.〔 Almost all of the existing interchanges are trumpet interchanges, except for Lučko, which is a stack interchange, and Jankomir, Kosnica, Ivanja Reka and Sredanci, which are cloverleaf interchanges. The motorway follows Pan-European Corridor X, and forms junctions with Pan-European Corridors Vb and Vc within Croatia. 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, and in zones where fog is known to occur. The system comprises variable traffic signs used to communicate changing driving conditions, possible restrictions and other information to motorway users. There are numerous rest areas along the motorway, providing various types of services ranging from simple parking spaces and restrooms to filling stations, restaurants and motels.〔〔(【引用サイトリンク】 url = http://www.hac.hr/en/motorways/rest-areas/ )〕 The A3 motorway is operated by Hrvatske autoceste, the state-owned company tasked with the management, construction, and maintenance of Croatian motorways.〔〔(【引用サイトリンク】 url = http://www.hac.hr/en/about-us/mission/ )〕 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「A3 (Croatia)」の詳細全文を読む スポンサード リンク
