An autovía is one of two classes of major highway in the Spanish road system similar to a British motorway or an American freeway.
It is akin to the autopista, the other major highway class, but has fewer features and is never a toll road.
While autopistas are generally new routes, autovías are normally improvements to existing roads, so they may have tighter curves and less safe accesses, often with shorter acceleration lanes.
[3] The system can be regarded as a way for the Government to finance the construction of new roads without any initial outlay of money.
Autovía was also the name of a 2 car DMU train of the Ferrocarriles Nacionales de México that operated between Ciudad Juárez and Chihuahua, Mexico.
