The Autoroute 66 (A66 ) is a French motorway starting in Vieillevigne and end in Pamiers. It is part of the European Route 9 (E9 ) and the main routes from all over northern and central Europe to Andorra. The highway is partial toll road, the operator is the ASF ( Autoroutes du Sud de la France, to German: Motorways of the South of France ), there are no tank and rest areas.
At the moment she is to be regarded rather as a feeder and connecting stretch of the Upper Ariege Valley on the French motorway network. The highway turns into the N20 from Pamiers. With the exception of the Tunnel de Foix (about 6 km ) and a bridge over the Ariege ( 1 km), the N20 from the end of the highway to Tarascon- sur- Ariege four lanes.

As part of the project highway Toulouse -Barcelona is another ( piecewise ) expansion of N20, in part, on the current route, partially planned in parallel of Tarascon -sur -Ariege to the Spanish border at Puigcerdà (approx. 70 km). This removed part would then rededicated to the A66 and run from Pamiers about Foix, Tarascon- sur -Ariege, Ax- les- Thermes, the Tunnel de Puymorens and Bourg- Madame the Spanish border. Due to the difficult conditions (narrow mountain valley ) is not expected to be completed before 2020.
