Algonquin drops pre-cambered vehicular bridge into rural Ontario community in time for school

September 18, 2017

When the community of Clarence-Rockland, southeast of Ottawa, needed a replacement bridge for a small stream crossing, a custom-designed Girder Bridge from Algonquin Bridge was the solution of choice.

The contractor on this project, Arnco Construction, had a very positive experience with The AIL Group on a similar design-build bridge project in 2015. They were happy to be back in that comfort zone and to be using Algonquin Bridge on this one.

A quick and easy girder bridge installation

The crossing was the only connection for several homes on a dead-end road, so the bridge needed to be installed quickly to minimize road closure time and to be ready for the start of the school year– and the school buses.

Algonquin applied 100 mm camber to this girder bridge

The bridge was designed for standard highway traffic loads. To reduce load deflection, a 100 mm camber was added to the girders at the factory before the modules were built. As the contractor was planning to paint the bridge onsite, we supplied the girders with their ends pre-painted.

The two longitudinal sections, along with the guiderail components and hardware, were shipped on one trailer load.

An Algonquin Bridge featuring a painted steel deck with complete joint-penetrating welds

The bridge also featured a textured steel deck with a painted finish. Also, complete joint-penetrating welds at the deck surface joints allowed for ample run-off at each end of the bridge.
