The City of Edmonton, with funding provided by the Government of Alberta, is advancing construction on Stage 3 of the Terwillegar Drive Expansion Project. 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
These improvements will support current and future traffic, transit and active transportation needs. Construction is expected to take approximately two years to complete.
Sections of Terwillegar Drive approaching Windermere Boulevard, both northbound and southbound, for short periods, 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.
Further south along the same corridor, a private developer is currently widening 170 Street south of Windermere Boulevard. Construction is anticipated to be complete in fall 2026.
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 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.
Terwillegar Drive is a key north-south route connecting growing communities across southwest Edmonton. Once completed, the expansion project will increase capacity and provide all users, including vehicles, cyclists and pedestrians, with a safe and efficient route. Stage 3 is the final stage of the Terwillegar Drive Expansion Program.
