Rapid Bridge Replacement
Dufferin Construction replaced a four-span overpass over Highway 403 in Hamilton using the Rapid Bridge Replacement Technology. While Dufferin Construction has worked on contracts of this nature for the Ministry of Transportation of Ontario before, it was the first multi-span replacement in Canada. In addition, two different rapid bridge replacement technologies were used, one for the two centre lanes of the overpass (self-propelled modular transporters) and another for the two outside lanes (jack and slide). Extensive engineering, planning and preparation were required to successfully fulfill this mandate within a 51-hour timeframe (80 hours had been allocated by the MTO).
