Coast Meridian Overpass
Location: Coquitlam, BC Contract Value:
The Coast Meridian Overpass was completed in 2009 connecting North and South Port Coquitlam, BC. At the time, it was the longest single-span launched steel bridge in North America crossing over 3 spans at 125 metres each. It was the heaviest at over 5,170 tonnes and it was the first cable-stayed launched steel bridge in North America. We needed to break some records having to overcome limited pier accessibility and capacity due to a fully operational 55 track CPR Train Yard and a very shallow bridge profile of about 3 metres. To launch this heavy bridge across multiple spans, temporary stay-cables and a long 40-metre temporary launching nose were employed. Our proprietary hydraulic launching system was used to push the bridge from one side to the other over 500 metres away.
