This new interchange crossing the TransCanada Highway was PCL’s first bridge structure since reentering the civil infrastructure market in British Columbia. The team’s scope included a 230-foot long, six-lane bridge; the realignment of Clearbrook Road and underground utilities; the construction of a high traffic volume roundabout; and a signalized intersection with new on and off ramps. The team installed approximately 85 tons of reinforcing steel with a stainless steel top mat in the bridge deck, and over two kilometers (1.2 mi.) of Superpave asphalt.
To reduce traffic disruptions and time working over live traffic, PCL’s onsite team preplanned and prefabricated much of their work. This was critically important during the four nights of demolition required to remove the old overpass. As well, bridge girders were fitted on the ground with all brackets, inserts, and formwork, and then lifted into place. This improved onsite productivity, reduced safety hazards to the workers and public, and greatly decreased the amount of formwork that needed to be placed over highway traffic. The PCL team’s execution was seamless: they delivered a bridge structure free of any quality control incidents and met the project schedule, which enabled the project to qualify for the federal infrastructure stimulus fund grant.
