George Washington Bridge

Groupe Lefebvre and Venture Construction (American subsidiary), in conjunction with Bishop/Sanzari, have waterproofed the bottom level roadways of the bridge, as well as its access ramps on the New Jersey side.

A pre-rolled type 3 membrane was also mechanically applied on the bottom slab of the bridge, and a methyl methacrylate membrane was installed on the access ramps.
