Groupe Hexagone Uses Prefabricated Modular Steel Bridging to Minimize Impact During Highway Construction
Acrow Bridge provided Groupe Hexagone, a major Quebec-based contractor, with the first Acrow detour bridge used on a major highway in Quebec. The bridge carries three lanes of Autoroute 40 traffic, diverted from two highway bridges that are under construction. Autoroute 40 serves as the main truck route between Montreal and all points west. “Our detour solution is helping to minimize work zone impact, maintaining traffic flow while protecting construction workers and motorists,” said Benoit Forget, Quebec regional director at Acrow Canada. “This is a significant accomplishment, as the traffic volumes on Autoroute 40 are perhaps the highest in Quebec, with truck loading typically as heavy as 63 tonnes.” The Acrow bridge used on the Groupe Hexagone project is situated beside the two bridges under construction that transport eastbound and westbound traffic, respectively. At 27 m in length with a roadway 12.8 m in width, the bridge is one of the wider through type bridges that Acrow has produced in its 60+ year history. The detour features Acrow’s standard steel decking overlaid with asphalt. More than 43,000 vehicles cross the bridge every day. “The use of detour bridges has grown significantly in recent years as more and more contractors use them to stay on or ahead of schedule and control costs, while providing a safe and dependable route for traffic,” said Bill Killeen, president and CEO of Acrow Bridge. “The Acrow detour bridge, which can be rented or purchased, is particularly popular because of its modular steel design. Durable and easy to assemble, dissemble, transport, store and customize for future use, many contractors end up purchasing our bridges, because they are a cost-effective investment and proven competitive advantage.” Acrow bridges used as temporary detours address two major issues during highway and road construction. By providing a temporary roadway that is predictable and unchanging, traffic disruptions are significantly reduced while the safety of motorists and construction workers is greatly enhanced. This is a safer, faster and more economical alternative to “phased” construction in which lanes are moved as needed to divert traffic around work sites. Acrow detours also meet multiple highway transportation standards. Fast and easy to transport and assemble, they can be built and erected in a matter of hours or days.

By selecting Acrow’s modular steel bridge over a traditional concrete and steel temporary detour bridge, the contractor will be able to reuse the Acrow bridge on future projects, achieving the desired length, width and strength by simply using more or less bridge components. Also, the Acrow bridge can be installed and removed in less time and at less cost, enabling projects to be completed faster and more profitably.
