Bridge Rapid Replacement with Self-propelled Modular Transporters

摘要

Highway 417 is a major freeway running through the City of Ottawa, Ontario, Canada. Constructed between 1959 and 1967, the freeway carries more than 150,000 vehicles each day. Five of the twin bridges carrying eastbound and westbound traffic along the corridor are nearing the end of their expected lifespan with severe deck deterioration and are in need of rehabilitation or replacement. The Ontario Ministry of Transportation (MTO) retained McCormick Rankin Corporation (MRC) to design the replacement of these bridges in conjunction with a major reconstruction/ widening of Highway 417.
