Two accidents on the Golden Ears Bridge snarled traffic during the morning rush hour Thursday.
The first crash occurred around 7:25 a.m. in the southbound lanes of the bridge over the Fraser River, which links Pitt Meadows, Maple Ridge and Langley.
Ridge Meadows RCMP are investigating the accident between a SUV and car. Police said one person was taken to hospital with non-life threatening injuries.
Langley RCMP responded to a second crash in the northbound lanes after a motorcycle slammed into the back of a car.
Cpl. Holly Marks said their investigation has revealed speed was a factor in the collision and witnesses report the motorcycle had been switching back and forth between lanes.
"After the last lane change was completed the motorcycle collided with the back of another northbound vehicle. This spun the vehicle around causing it to collide with barricades on both sides of the bridge," she added.
The occupants in the vehicle were uninjured. The motorcyclist - a 23-year-old man from Surrey- was taken to hospital with non-life threatening injuries.
The crashes shut down several lanes on the bridge for two hours and caused traffic jams along its feeder routes.
The Pitt Meadows Fire Department said a third crash took place after a driver who was stuck in traffic made an illegal U-turn.
The bridge lanes have since been reopened to traffic.
