35Km of section completed between St-Constant and Vaudreuil-Dorion, originally designed to relieve heavy traffic on the 40 through Montreal by diverting it by the South Shore. Of all the new structures required, 20 are precast concrete, including 18 viaducts and 2 major bridges, Beauharnois overlooking the canal of the same name and St-Laurent spanning the river.
The 940 NEBT concrete beams were produced, delivered and installed to complete these structures, including beams up to 45 meters long, the longest in Quebec.
These beams required a very specific delivery and installation logistics. For the two bridges, the longest ones were installed from a "launcher" which rests on the completed structure to carry forward, in suspension, the beam to be installed.
This project is the result of a public-private partnership (PPP).
