Traffic Counterflow Operations
Last updated on July 5, 2024
A counterflow system allows operators to change the direction of traffic in one or more lanes to create more efficient traffic flow, especially during peak periods.
Operators monitor the Lions Gate Bridge and George Massey Tunnel 24/7, adjusting lanes based on traffic, visibility and weather conditions.
