MMM will share its expertise in rapid bridge replacement as part of National Engineering Month at the Niagara Engineering Week Luncheon in Niagara Falls, Ontario on March 6th.
Matthew Bowser, James Sherlock, and Jeff Smith from MMM’s Mississauga Bridges Group will host the morning technical session on the topic of Rapid Bridge Replacement Using the Jack and Slide Method. The presentation will feature MMM’s work as prime consultant for the preliminary and detailed design of the Highway 406 Glendale Avenue Rapid Bridge Replacements.
The recently completed lateral slide for the twin overpasses in St. Catharines, Ontario involved the advanced construction of 52-m long, three-span superstructures on temporary supports directly adjacent to the northbound and southbound lanes of Highway 406. Using a short-duration full-closure over two weekends, the old superstructures were then jacked and slid onto temporary supports, followed by a jack and slide installation of the new superstructures.
This method of rapid bridge replacement offers the benefit of reducing the long duration traffic impact that occurs during conventional bridge replacement projects with staged construction.
Along with showcasing the Highway 406 Glendale Rapid Bridge Replacements, the technical session will include several other projects that utilized jack and slides during construction.
The annual Niagara Engineer Week Luncheon is part of National Engineering Month – Canada’s biggest celebration of engineering and engineering technology.
