BOLTON, ONT. — Acrow Bridge, an international bridge engineering and supply company, has supplied a temporary detour railroad bridge to the City of London, Ont. to help keep rail traffic moving during a major road widening project.
Construction is taking place within the busy Western University district, where a bridge dating from 1931 has carried Canadian Pacific Railway traffic over two lanes of vehicular traffic that has been subject to heavy congestion at peak travel times. Once construction is complete, the wider road will carry four lanes of traffic.
The first segment of the overall project was to replace the existing rail bridge to accommodate the wider road below. An Acrow Bridge was rented as a detour to carry the rail traffic alongside the existing structure while the permanent bridge is constructed.
The contractor for the project is McLean Taylor Construction and design engineering services were provided by consulting firm AECOM.
According to a release, the modular steel bridge is 70-feet-long-by-18-feet-wide. It has rails over a timber deck and a Cooper E80 load rating. Assembly and installation of the temporary structure was completed in five days in September. Due to site area access, the bridge was assembled nearby and then lifted into place using two cranes. It was open to rail traffic in November and it is anticipated it will be in place until May 2018.
“Acrow’s structure proved the ideal solution for this project,” said Jack Bishara, P.Eng., project engineer with Acrow. “Using a rental structure allows for a fixed dollar amount to be allocated to the detour bridge and it can help ensure a project stays on or ahead of schedule, important for both contractors and government entities alike.”
