A serious collision on the Mary Hill Bypass Wednesday morning snarled traffic for an hour but caused no injuries.
Shortly after 8 a.m. a Mazda heading east on the bypass was turning left on to Broadway Street when it crashed with a westbound minivan.
The minivan then spun around and struck a third vehicle.
There appeared to be extensive damage to the vehicles, but no injuries were reported at the time police attended.
Coquitlam RCMP are urging any witnesses to contact them at 604-945-1550 and quote file number 2012-8820.
