concrete evidence was engaged by cpb contractors to construct three bridges as part of the m1 widening between tuggerah and doyalson. these being the sparks road overpass, the doyalson exit ramp and the st johns road
bridge. This extremely challenging project took two years to complete, and had our teams working on several different work fronts at any given time, with all work carried out over the live motorway.
the m1 pacific motorway is a critical link in the national land transport network, and part of the sydney to brisbane corridor, one of the busiest transport corridors in australia.
