Like the nearby Fauvettes viaduct, the Montjay tunnel once served as the old Paris-Chartres railway line. In the middle of the communal forest of Bures-sur-Yvette, it punctuates the straight and rolling line leading to the viaduct.

It's really dark there, be careful where you put the wheels if you don't have a light! (a priori, there is no trap)
