Construction just marked a big milestone at the B.C. coast. Work is now underway on a 2.6-kilometre tunnel through Burnaby Mountain, a massive engineering effort that the project has been preparing for more than six years.
The tunnel is required to minimize impact of the expansion on the local community, Trans Mountain says.
Specialized boring equipment will work over the coming months to construct the tunnel, which will house three delivery pipelines. It will connect the Trans Mountain Burnaby Terminal – at the end of the pipeline – with the Westridge Marine Terminal, where tankers are loaded.
