A14 autoroute
The autoroute A14 is an autoroute in the western suburbs of Paris, France.
The motorway starts at La Défense in Hauts-de-Seine and ends at Orgeval in Yvelines. The A14 was built to relieve the congested A13 between Paris and Normandy. The A14, opened in 1996, is operated by the Société des Autoroutes de Paris Normandie. The motorway is 15.6 km (9.7 mi) in length and is subject to a toll. The A14 serves no localities between La Défense and Orgeval and is only a relief road of the A13.
A motorway exit near Saint-Germain-en-Laye was planned but was denied by the French president, François Mitterrand, after mayors wanted to prevent excessive car use in the Forest of Saint-Germain-en-Laye. Other exits were planned but their construction is blocked by communal councils.
A motorway exit is projected west of the Montesson toll bar. The mayor of Montesson has placed a condition on approval of the project that the exit may be constructed if a dual-carriageway relieving the RD121 is also built. Public consultation is in progress.
Many bridges and tunnels were built to carry the motorway. Two long bridges and a tunnel of 2.8 km long were built. The tunnel, built for 4.5 billion FRF, was built to preserve the forest of Saint-Germain.
The toll has a price that varies with the hours of the day. Free access to the motorway is given to drivers practising carpooling.
