More than just a new link between two shores, the Grandes-Fourches bridge is part of a major transformation for this area of Sherbrooke. Its construction, combined with the redevelopment of Rue des Grandes-Fourches Nord, has made it possible to rethink travel, modernize urban infrastructure, and prioritize sustainable mobility. Its architectural lighting also helps give the cityscape a new signature.

The challenge

Across the bridge's 63-meter span, the architectural drops had to follow a complex geometry composed of three distinct radii of curvature. This configuration was not suited to traditional formwork methods, especially since the design did not allow for any visible tie rods.

Our approach

The solution took shape long before arriving on site. Thanks to 3D modeling, the formwork was precisely designed and then prefabricated in our facilities before being transported to the site. The symmetry of the drops on each side of the bridge also allowed for the reuse of the same formwork sections, optimizing both resources and work sequences.

Results

The result combines technical performance with an architectural signature in a structure that fully contributes to the renewal of the sector. Beyond its function as a crossing, the new bridge helps create a safer, more accessible environment adapted to different ways of getting around, while leaving its mark on the Sherbrooke landscape.
