Original story below…
Traffic through the George Massey Tunnel is down to one lane each way due to a water leak at the north end of the crossing.
According to the B.C. Ministry of Transportation, the closure was caused by an oversized vehicle travelling northbound on Highway 99 striking a sprinkler head at the north end of the tunnel.
Both northbound lanes are closed but the counterflow is in, meaning a single lane is moving in either direction. A detour route is available.
In a tweet at 3:44 p.m., Delta Police say the closure is expected to be relatively short-lived as repair crews are on scene.
