TRAFFIC – Signal timing on Columbia Street corridor to be ‘optimized’

Signal timing at intersections within the Columbia Street corridor between 1st Avenue and 6th Avenue will be “optimized” beginning Oct. 18, and changes to the left-turn lane at Columbia and Third Avenue will go into effect.

The dual left-turn lane at the Columbia and Third intersection will be converted to a single left-turn lane, allowing left turn movements in both directions to occur concurrently and more time for free flow of east-west straight through traffic, says a City news release today (Oct. 14, 2025).

Pavement markings and overhead signage will be updated to reflect the new configuration.

“Traffic analysis shows that the revised layout will significantly improve east–west travel and overall intersection performance while maintaining similar queuing times for left-turning vehicle,” said the release.

“These updates are designed to support current traffic volumes and provide flexibility to adapt to future development and growth in the downtown area.”

The City’s transportation department used recent vehicle and pedestrian count data from the downtown network to guide the changes. Traffic flows will be monitored to ensure the adjustments are working, and refinements will be made based on driver behaviour and performance.

“This work has been strategically scheduled to begin after the completion of the Overlanders Bridge Maintenance Project, minimizing overlapping construction impacts and avoiding additional congestion along this key route.

“The upcoming changes also build on recent paving upgrades along Columbia Street, helping to create a more coordinated and efficient transportation corridor. Drivers along the Columbia Street corridor can expect smoother travel with better traffic signal timing and fewer stops along the way.”
