At the time of the collapse of the 54-year-old concrete structure, a loaded dump truck was crossing and was left stranded and partially submerged in the creek. Fortunately, there were no injuries as a result of the accident, but the truck remained where it fell for four weeks until a comprehensive plan was put in place to safely remove its cargo and fuel and proceed with a complicated extrication. Ultimately, the truck was lifted off with a giant crane, an event that attracted media and a large crowd of onlookers.
The Acrow bridge was purchased by Elgin County, which anticipates reusing it for future projects. The single-lane span is 54.8 meters (180 feet) long and 5.5 meters (18 feet) wide with an epoxy aggregate anti-skid coated steel deck and a CL-625 ONT Truck load rating per Canadian Highway Bridge Design Code. Construction on the temporary bridge began on July 3 and was completed on August 15. It opened to traffic on August 20 and is expected to be in place for two years.
Spriet Associates Ltd. of London, Ontario is the design engineer for the project and the contractor is Maclean Taylor Construction Ltd. of St. Marys, Ontario.
“Using a temporary detour bridge can help ensure the project stays on or ahead of schedule, important for both contractors and government agencies,” said Gordon Scott, Senior Project Manager and Structural Engineer at Acrow Bridge. “Acrow modular bridges, available for rent or purchase, are cost-effective and provide a safe and dependable route for local residents and area businesses.”
