Evergreen Line construction opens 3rd sinkhole in Port Moody

Construction of the Evergreen rapid transit line has opened up a third sinkhole in the streets of Port Moody, B.C., officials have confirmed. 

The newest sinkhole forced the closure of the southbound lane on Clark Drive near Seaview Drive.

Amanda Farrell, the executive project director for the Evergreen Line Project, said the hole opened up while the tunnel-boring machine was undergoing maintenance.

"The size of it is about six metres by six metres and possibly five metres deep. Crews are still assessing that," she said. 

Crews are expected to continue working to fix it this morning, but it remains unclear how long that work will take, said Farrell. 

"I should have that information in the next day or so," said Farrell.

The first of the two sinkholes opened in the parking lot of a building on Chateau Place last fall, and a second appeared on Cecile Drive on Jan. 2.

Residents have also raised concerns about cracks appearing in the walls of their homes, noise, vibrations, road closures, parking and what happens if there are problems after construction is completed.
