Transportation and infrastructure contractor Flatiron's Canadian division has completed a 12 month project to build the 300 metre long Donald Bridge, using three Terex cranes.
The contractor, working on the CAD$40 million Trans-Canada expansion, met several challenges when building the bridge crossing the Columbia River at Donald. Steep slopes, a small workspace and limited access led to the contractor bringing in three Terex cranes to assist with construction.
A Terex RT 780 rough terrain crane, HC 110 hydraulic crawler crane and a 230 US ton capacity HC 230 crawler crane were on site for 12 months. The majority of the heavy lifting went to the larger crawler while the smaller RT 780 and HC 110 were used for support projects, including assisting with bridge substructure building, pier work and coffer dam construction.
The Trans-Canada Highway expansion in south eastern British Columbia involves the upgrade of a 3.5 km stretch of Highway 1 south of Donald from a two-lane configuration into a modern four-lane highway. In addition to the Donald Bridge, the project also includes the construction of a second bridge over the Canadian Pacific Railroad.
