Structal-Bridges recently concluded an agreement with Aecon Group Inc. for the fabrication of 1,800 tons of steel components in the scope of the North Channel Bridge Replacement Project in Cornwall, Ontario. Overlooking the St. Lawrence Seaway, this bridge is a key road link between Canada and the United States.
Structal-Bridges will fabricate 22 box girders for this 1,100-ft. (335 m) bridge. Each piece will measure an average of 98 ft. (30 m) in length and weigh between 75 and 95 tons each. The business unit will also erect the bridge components using the launched-girder erection technique. Goodco Z-Tech, a product of Structal-Bridges, has been mandated to design and fabricate 20 pot bearings assemblies, including 12 PF-Series fixed bearings, to be installed at piers 1, 2 and 3, and 8 PMG-Series unidirectional bearings for the abutments.
The components will be fabricated at the Quebec City and Laval plants from November 2011 to July 2012 while erection is slated to take place between April and August 2012. Construction of the new bridge is scheduled to be completed in 2016.
