The City of Toronto has retained TSH for the inspection and rehabilitation of the Prince Edward Viaduct.  The project will involve a detailed visual inspection, delamination survey and rehabilitation pre-design of the historic viaduct spanning over the Don River, Don Valley Parkway and Bayview Avenue. 

The Prince Edward Viaduct is a vital City of Toronto structure, as it connects Bloor Street East, on the west side of the system, with Danforth Avenue on the east, and spans  the Don River Valley and the Don Valley Parkway, one of Toronto’s major north-south highways.  It carries six lanes of Bloor Street traffic, as well as the TTC Danforth Subway line.  The viaduct is also an important heritage structure, consisting of structural steel arches and concrete piers, and is a recognized landmark in the City of Toronto.

TSH Structural Engineers have extensive experience in this type of work, and typically carry out 1000 bridge inspections each year for various municipal and provincial clients. 

In addition to the Prince Edward Viaduct, TSH has been retained for the inspection and fatigue analysis of the Garden City Skyway, a 2.2 km bridge spanning over the Welland Canal, one of the largest bridges in the Province of Ontario.  TSH Structural Engineers also carried out the inspection of the Alexandra Bridge, a historic truss bridge spanning the Ottawa River adjacent to Parliament Hill.  This bridge is a heritage structure, and a key landmark in the City of Ottawa.
