Acrow installs temporary bridge for Brownsburg-Chatham rehabilitation

Acrow supplied a modular steel bridge in Brownsburg-Chatham, Quebec, to keep traffic moving while the Henri-Raby Bridge is rehabilitated. The temporary crossing is meant to preserve safe access for vehicles and pedestrians through most of 2026.

Why it matters: - The temporary bridge keeps a key local route open while the Henri-Raby Bridge is rebuilt. - The solution preserves access for residents, vehicles and pedestrians in Brownsburg-Chatham. - The modular installation helps reduce disruption during a safety-driven infrastructure shutdown.

What happened: - Acrow designed and supplied a modular steel bridge for Rue Principale over Rivière de l’Ouest in Brownsburg-Chatham, Québec. - The temporary bridge replaces an aging structure owned by the Ministère des Transports et de la Mobilité durable. - The original bridge was closed in December 2024 for safety reasons. - The bridge is expected to remain in place throughout most of 2026.

The details: - The Henri-Raby Bridge was originally built in 1940 and had reached the end of its service life. - The structure had load restrictions in place since 2022 to help ensure it met load-bearing requirements. - The temporary bridge was supplied as a rental to contractor Maurécon Inc. - Gelco Construction Inc. assembled and installed the bridge. - The bridge is 180 feet long, or 54.86 meters, and 18 feet wide, or 5.5 meters. - The bridge includes an epoxy aggregate deck. - The structure was designed to a Live Load of CL-625. - Crews installed the bridge using a crane-assisted launch method. - The launch method was intended to support efficient placement and limit impacts on the surrounding environment. - The bridge carries single-lane, bi-directional traffic controlled by a traffic signal. - The bridge accommodates both vehicles and pedestrians.

Between the lines: - The project shows how modular steel bridges can keep transportation links functioning during lengthy rehabilitation work. - Acrow said the installation demonstrates the rapid-response capability of modular steel solutions for agencies managing complex infrastructure projects. - The temporary crossing also allows construction to proceed without waiting for a permanent replacement to open.

What's next: - The temporary bridge will stay in use while the Henri-Raby Bridge replacement project moves through planning and design. - Traffic on the route will continue to be managed with a signal until the permanent solution is ready. - Acrow's company information notes the company has served transportation and construction customers for more than 75 years.
