The tunnel boring equipment for the new $1.4 billion Burnaby to Coquitlam Evergreen Line is expected to make another stop underground in Port Moody in early March, requiring some advance construction work.
Crews are working to strengthen the soil below the roadway at Clark Road and Seaview Drive before the boring equipment arrives. The work includes injecting cement grout into the ground approximately 40 metres below the surface, and dewatering the area to permit workers to safely do required maintenance work and change the cutterhead tools on the boring machine.
Safety fencing will be installed and lane closures will be required on Clarke between Mount Royal Avenue and Ingersoll Avenue to permit the work. However, one lane in each direction will always remain open.
On Seaview, traffic will have to be rerouted but will be restored on the east side of Clarke Road in early March and in April on the west side.
According to the latest report, the tunnel boring project is 40% complete with digging expected to cross the Coquitlam border later this spring.
