Tri-Cities residents voiced their concerns over the progress of the Evergreen Line construction at a meeting on Wednesday night.
The meeting follows four sinkholes opening up along the construction route in Port Moody since last October.
The last sinkhole formed a little more than a week ago on Clarke Road and was about two metres wide. Lane closures and detours had to be put in place and those tied up traffic for several days.
People living in Coquitlam are worried the boring of the tunnel is compromising soil integrity and could lead to more sinkholes or damage to their property.
“Soil conditions are unpredictable and that’s the main issue tonight,” Coquitlam Mayor Richard Stewart told Global News.
“It seems is that their concern is everything that can be done is being done to mitigate this kind of challenge as it relates to the tunnel boring machine.”

The Evergreen Line has been plagued with sinkhole issues. In late October a sinkhole formed above the Evergreen Line tunnel boring at Chateau Place, near to Cecil Drive. In January, another sinkhole opened up above the construction, blocking off traffic.
Sinkholes are not the only issues residents brought up. Other concerns were voiced around construction noise and strain on the existing structure.
The tunnel boring in Coquitlam will start in late July and is expected to last about three months. It will end at Clarke Road and Robinson Street.
