Aininian Autoroute 1 (A1), commonly known as L'Aininienne (The Aininian), is the main autoroute connecting Northern and Southern Ainin. Composed of four non-contiguous stretches of road connected by vehicle ferries, it connects most of Ainin's major cities, including Beaurepaire, Huimont, Talon and Bounèsquebourg. Due to its strategic location, it is the busiest autoroute in Ainin and one of the most important transport links between Talon and Beaurepaire.
Autoroute 1 was first designated in 1950 and connected Beaurepaire with Talon through existing coastal highways in West Ainin. Since then, it has undergone substantial rerouting and extension. In 1963, a more direct route through the Cordière Mountains was completed, with much of the original coastal route becoming Autoroute 71. In 1977, it was extended eastward to Hibourg, where it connected with ferry services to Huimont. In 1991, the non-contiguous tracts of A1 in Isle-Royale, Mercier and Risagne became part of the autoroute, making it the only numbered motorway in Ainin that includes ferries as part of its regular route.
At a total length of 3,817 km (2,370 mi), it is the longest dual carriageway in Ainin.
Description
Mercier
A1 begins at a trumpet interchange with Autoroute 60 in downtown Dartan, Mercier. The highway, located at ground level, is three lanes wide in each direction with Line 1 of the Dartan Tramway running in the central reservation. Several pedestrian overpasses and city streets pass over the highway, but exits are few and far between. After intersecting with Autoroute 360, the city's ring road, A1 widens to five lanes until its junction with Mercier Route 50, which leads to Dartan Arceneaux International Airport. It then returns to three lanes as it enters the Dartan suburbs. In the suburb of Boisgorgnes, it intersects Autoroute 81, which connects Mercier's capital of Dartan with its second-largest city of Avran.
As it exits the city, it further shrinks to two lanes as it follows the east bank of the Bécancourt River before crossing the Central Mercier Hills. The road curves as it passes through narrow valleys and the Montfort National Forest in the Hills. Further north, it passes many fields and several villages as it crosses the Mercier countryside. As it approaches the island's northern coast, it merges into the three-lane Autoroute 81, forming a concurrency. The concurrency continues into downtown La Grève, where traffic is once again segregated by an interchange. A81 continues westward to Fanay while A1 turns north towards the Port of La Grève, where it abruptly ends in an industrial zone near the ferry terminal.
Jaspère and Bounèsque
Autoroute 1 picks up at the Port of Beaurepaire, across the Strait of Mercier. As it enters the city core, it expands to a record twelve lanes organised into a local-express configuration. As the main north-south highway in the Beaurepaire metropolitan area and as the road linking the city to its international airport, this stretch of A1 is the busiest in the country, seeing upwards of 650,000 cars on a single day. It intersects several other autoroutes in Beaurepaire, including A6, A101, A106 and A201. In Beaurepaire, A1 runs on the west bank of the Lièsverval River, while A201 runs parallel on the east bank until the latter crosses the river and joins A1 north of Saint-Hyacinthe Airport.
As it leaves urban Beaurepaire, the motorway progressively shrinks to a more manageable six lanes. It crosses the Lièsverval River at the Jean-François Grizeau Bridge to follow the west bank of its tributary, the Loze River. Entering the Central Jaspère Mountains, it further shrinks to three lanes and curves through mountain valleys and manmade passages. As it enters the large Colise Valley, A301 branches off of the main A1 route to serve the northeast coast of Jaspère. As it continues to wind through the mountains, near the regional capital of Fromont, it also has intersections with A206, A44, A144 and A406. As it nears the northern coast of the peninsula, A244 intersects and A301 rejoins A1. It crosses the Jaspère Canal on the Sœur-Pouliot Bridge before crossing A103 to follow the west coast. 60km later, it crosses into Bounèsque province.
As it approaches the provincial capital of Bounèsquebourg, it expands to eight lanes. The highway runs directly through Downtown Bounèsquebourg, intersecting A67 and A501. It then returns to three lanes as it turns towards the city's western suburbs, before again turning north to follow the centre of the isthmus. It intersects A18 near Taison-La-Chapelle and turns north-east towards the city of Daque, where it intersects Autoroute 3, the main highway serving the Gold Coast. A1 turns northwest shortly afterwards towards the alpine city of Bastide, where it once again intersects A18 as well as the city's ring road, A218. It then turns northeast into the Cordière Mountains, where it shrinks to two lanes.
Montagnes, Linaque and Ponant
Crossing into Montagnes, A1 curves significantly as it makes its way through narrow natural passes and manmade tunnels. As it emerges into the Marlane Basin, it intersects A266, after which it returns to three lanes as it follows the shoreline of Lake Sainte-Hélène and its outflow, the Evmont River. It then makes its way through the agricultural Nevan Valley as it curves east towards the provincial capital of Marlane-la-Prairie.
Isle-Royale
Autoroute 1 picks up near the Neubourg ferry terminal as a four-lane motorway.
