Autostrada A15 (Italy)

The first phase of this motorway, dating to the 1950s, was designed to provide an alternative route between the Po Valley and the coastal Tyrrhenian Sea. The construction required several viaducts and tunnels to attain the maximum altitude of 745 metres above sea level at the entrance of the tunnel crossing. Built as a dual carriageway (divided highway), it is very curvilinear and challenging to drive and, therefore, has long been used for testing new heavy duty vehicles. Except for short stretches of the highway, the road surface is not porous or fitted with storm drains, making it difficult to negotiate during heavy rain. ==Route==

, with the steel monument in the shape of a "tuft" placed in the large traffic island between the two carriageways. The motorway begins from the A1, near Parma. From the Parma Ovest (West Parma) exit the highway climbs through the Taro Valley with exits to Fornovo di Taro, Borgotaro and the village of Berceto, all within the Emilia-Romagna region. After traversing the tunnel, the highway continues into Tuscany, with exits to Pontremoli and Aulla. Shortly after entering Liguria it intersects the A12 at Santo Stefano di Magra, a few kilometres from La Spezia. There are five service stations and rest areas along the way.

A plan to extend the motorway route to the north through Fontevivo, Martignana di Po and Nogarole Rocca, linking to the A22 (the Autobrennero) around Verona, has been proposed. Land has been secured both for straightening the present route through the construction of new viaducts and tunnels and for the proposed extension. The town of Villafranca in Lunigiana and neighbouring municipalities have petitioned for opening such a new toll motorway. Negotiations have begun with private motorway companies and the Ministry of Infrastructure and Transport. == See also ==
