WATCH | Learn how the counterflow system on the Lions Gate Bridge works:
Maintenance contractor Miller Capilano Highway Services monitors more than 40 cameras on the bridge and surrounding roads from the Transportation Management Centre of British Columbia in Coquitlam. These contractors are responsible for manually changing the lane directions based on traffic volumes and safety.
Upgrades to the current system have already included new LED lane signal heads, streetlights and cameras. The systems will be tested this weekend.
Outside of the overnight closures, the bridge and causeway will be open to traffic with a partial system counterflow in place. Pedestrians and cyclists will have access at all hours on the east sidewalk.
According to the province, an estimated 60,000 drivers cross the Lions Gate Bridge daily.
