BC Transit Alrt Tunnel
New Westminster, BC, Canada
BC Transit’s Light Rapid Transit (Skytrain) line dips underground as it passes through New Westminster near the sky bridge. As Prime Consultant to BC Transit, CWMM designed the 590 foot (180 metre) section of tunnel and retaining structures west of the Columbia Station, as shown above. With a construction cost of $70 million, this project involved substantial utilities relocation, underpinning, and support of existing buildings in relatively poor soil conditions during construction.
