A86 : Le Défi d'un tunnel à double étage
The Duplex A86 is a 10 kilometer underground highway buried more than 90 meters deep.

The result of a succession of technical prowess born from the imagination of visionary engineers, the Duplex A86 allows you to cross all of western Paris in a few minutes.
