Cable-Stayed Bridges - New Port Mann Bridge

The British Columbia Ministry of Transportation is set to replace an existing through arch bridge that carries Highway 1 across the Fraser River with a new eight lane cable-stayed bridge. Bridge projects in Vancouver are a cause of considerable controversy, and there has been opposition to building another highway bridge that brings more cars into Vancouver.However, the New Port Mann Bridge is set for completion by the end of 2012.

Currently 327 precast concrete box girder segments are being moved from Coquitlam to the south side of the bridge (in Surrey) where they're launched by this huge truss system for the assembly of the south approach to the bridge. After the south approach is completed, they'll reassemble the launching system on the north side of the bridge. Meanwhile the towers are almost at deck level and will top out at 500 ft, taller than the nearby Alex Fraser Bridge.

We'll take another look at this project tomorrow.
