A86 : Le Défi d'un tunnel à double étage

2023 Documentary TV Movie

The Duplex A86 is a 10 kilometer underground highway buried more than 90 meters deep. This concrete tube, measuring the equivalent of more than 30 lying Eiffel towers, is the longest tunnel in France. 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.

🎬 MovieFinder's Take

A86 : Le Défi d'un tunnel à double étage is an acquired taste at 0.0/10. We recommend checking the trailer and synopsis before diving in.

Not every film is made for everyone. Read the synopsis, watch the trailer — you'll know right away if it's for you.

Released in 2023, this film holds up just as well today. Best for: genre fans and those open to something unconventional.
