A graceful, painted Bowstring Truss design from Algonquin Bridge frames up a rather beautiful view of St. Margarets Bay for motorists entering the area via the new Highway 103 connector at Ingramport, near Halifax. However, it’s the trail users who really get the best views as they cross the new span on the historic rails-to-trails route.
Design-Build project part of overall Highway 103 connector
The new trail bridge was provided through a design-build solution and was the final component of a three-year project to create a new exit along a 20 km section of the main route serving the South Shore. Using 3D modelling to optimize the structure, Algonquin engineers created the design with an H-Section floor beam to facilitate easy delivery in two sections and quick on-site installation.
Bridge spliced and placed in half a day
Daily communication with the contractor, Dexter Construction, helped ensure everything went off without a hitch. The bridge sections were delivered, spliced together and placed within four hours. Dexter remarked that it couldn’t have fit more perfectly on the abutments.
As per the Nova Scotia Department of Transportation and Infrastructure Renewal’s specifications, we gave the bridge a long-lasting, three-layer paint system that will provide many years of low-maintenance service in this coastal environment.
Our AIL Group sibling company, Atlantic Industries Limited, was also involved on this connector project, with the design and supply of a stream crossing using a Super•Cor Low-Profile Arch with Vist-A-Wall Precast Panel Walls.
Algonquin trail bridges can be found across Canada
Algonquin has developed a specialty in recreational trail and pedestrian bridges with many installations across Canada. Here are some examples:
