Project Update - June 2026
Construction on Stage 3 of the Terwillegar Drive Expansion Project began in early May and is expected to take approximately 2 years. These improvements will support current and future traffic, transit and active transportation needs.
This stage includes important upgrades to the existing interchange over Anthony Henday Drive, including:
- A new northbound bridge over Anthony Henday Drive
- Repurposing the existing bridge for southbound traffic over Anthony Henday Drive
- Two new loop ramps to allow for free-flow turning movements
- Corridor upgrades with three lanes in both directions
- A new pedestrian/cyclist bridge connecting the Windermere and Haddow communities
While this work is underway, sections of Terwillegar Drive approaching Windermere Boulevard, both northbound and southbound, will experience lane reductions to accommodate construction required to complete the roadway widening. The work at the Windermere Boulevard intersection is being prioritized and accelerated.
During construction, road users should expect congestion and longer commute times. In recent days, the City has worked with the contractor to ensure additional measures have been taken to reduce traffic disruptions as much as possible. The City will continue to monitor traffic flow and remains committed to finding opportunities to minimize the impacts on road users. The Traffic Disruptions Map will continue to be updated to reflect the anticipated impacts.
Traffic Impacts:
- During construction, two lanes of traffic will be maintained across Anthony Henday Drive; Terwillegar Drive lanes at Windermere Boulevard intersection will be prioritized according to optimal use at each phase.
- Short-term daytime and occasional nighttime lane closures may be required during off-peak periods.
- Impacts to Anthony Henday Drive, including temporary lane closures and reduced speeds, are expected.
- During construction, road users should expect congestion and longer commute times.
- Additional measures have been taken to reduce traffic disruptions as much as possible. The City will continue to monitor traffic flow and remains committed to working with all parties involved to minimize the impacts on road users.
- The Traffic Disruptions Map will continue to be updated to reflect the anticipated impacts.
