SkyTrain Evergreen Line construction progressing quickly (PHOTOS)

Construction on the $1.4-billion SkyTrain Evergreen Line is speeding along for a summer 2016 completion and opening.

Unlike the disruptive process for building the SkyTrain Canada Line, construction for the 11-km long, 6 station SkyTrain Evergreen Line has been smooth sailing with few complaints and relatively limited impacts on road traffic. Much of this can be attributed to the line’s route running alongside existing freight rail tracks, a 2-km long bored tunnel, and lessons learnt from the Canada Line.

Nevertheless, most Metro Vancouverites might be surprised to see how much Evergreen Line construction has progressed since shovels first went into the ground last year. Many columns have been poured and elevated track guideways in certain areas have been erected.

Next month, construction will reach a major milestone when the massive 9.84-metre diameter, 1,100 tonne tunnel boring machine begins digging a single tunnel that will fit two side-by-side tracks. Crews are now in the final stages of machine assembly.

Running 24 hours a day, and assuming there will be no issues that cause delays, it will take approximately a year for the tunnel boring machine to complete the underground tube which will reach a depth of 60-metres at its lowest point.

Seattle is currently in the process of building a new road tunnel to replace the Alaskan Way Viaduct. However, tunnel boring came to a halt last week when either a large glacial boulder or concrete chunk got stuck within the spokes of the 17.5-metre diameter machine. The machine now sits still 18-feet underground and after only completing one-tenth of the tunnel. It is not known when digging will resume.

Metro Vancouver also experienced costly and extremely lengthy delays with the recent Seymour-Capilano Water Filtration project. Machine-halting complications arose while boring the project’s twin side-by-side 7.1-km long tunnels through hard granite rock under Grouse Mountain at depths reaching 640-metres underground.

When the Evergreen Line opens, it will allow commuters to travel from Lougheed Station to the terminus at Lafarge Lake-Douglas Station near Coquitlam Centre in just 15 minutes. Trains will arrive every 3-minutes during most service hours.

    Excellent update. Good work Mr. Chan of keeping us up-to-date.

  • The Consortium

    I worked planning this line in 1990, Irwin Engineering of Toronto said no because of loose glacier pack on the high cliff of Burnaby Mountain above. Colin Cranston reported the deeper soil moves the cut on the North Rd. Port Moody hill from that pressure. 6 fault lines on Burnaby mountain. Cranston was the geology proff at the time. At that point the Social Credit team resigned in arguments. Instead a four lane upgrade highway was put in along the Barnett. The line was officially abandoned for reasons of safety. The new line leaving from Sapperton on a bi level grade through Essondale and into Coquitlam Station was never passed. The price tag quoted..you got taken for the first ride.
