Terwillegar Drive Expansion

Aerial view of Stage 3 of Terwillegar Drive Expansion

Stage Three includes road widening, Terwillegar Drive and Anthony Henday Drive Interchange upgrades, dedicated transit lanes and a shared pathway.

Project Update - April 2026

With site preparation now complete, construction on Stage 3 of the Terwillegar Drive Expansion Project will begin this spring and is expected to take approximately two years.

This stage includes a new interchange and pedestrian/cyclist bridge over Anthony Henday Drive, along with corridor upgrades to support future traffic, transit and active transportation needs.

Traffic impacts:

During construction, two lanes of traffic will be maintained in each direction.
Short-term daytime and occasional nighttime lane closures may be required.
Minor impacts to Anthony Henday Drive, including temporary lane closures and reduced speeds

About the Project

Key Upgrades in Stage Three:

Terwillegar Drive and 170 Street will be widened, and the interchange at Terwillegar Drive/170 Street will be improved to better handle traffic flow.

A new pedestrian bridge will be built across Anthony Henday Drive, providing a safe route for pedestrians and cyclists.

Matching those in Stage One, new transit lanes will be added to improve public transportation.

A partial cloverleaf interchange will be built, including a new northbound bridge and loop ramps. This will improve access from Terwillegar Drive/170 Street to Anthony Henday Drive and handle future traffic demands.

Changes to Pathway Plans

Based on technical requirements, safety considerations, and feedback from community engagement in early 2022, the shared pathway will now be separate from the Terwillegar Drive roadway and interchange.

A new pedestrian bridge will be constructed over Anthony Henday Drive between Terwillegar Drive and Rabbit Hill Road. This bridge will connect the recently completed Stage One shared pathway with Ambleside, east of Currents of Windermere. This is a change from the initial design shared in 2022.

What We Decided Report

This report highlights what we heard during the Stage Three concept design engagement phase (April/May 2022) and what was incorporated into the preliminary design.

Funding

Stage Three is funded by the Government of Alberta. Planning, design and delivery of the project is being led by the City of Edmonton in partnership with Alberta Transportation.

Project History

Project Update - November 2025

Early works on Stage 3 have been completed. Work included building the head slope fills for the new Terwillegar Drive roadway bridge and a new separated pedestrian bridge. Completing the head slope fills allows the ground to settle before main construction work, which is anticipated to begin in spring 2026.

Stage 3 will include:

A new roadway bridge carrying northbound Terwillegar Drive over Anthony Henday Drive.
Reconfiguration of the existing bridge to carry southbound Terwillegar Drive over Anthony Henday Drive.
Two new loop ramps connecting southbound Terwillegar Drive to eastbound Anthony Henday Drive and northbound Terwillegar Drive to westbound Anthony Henday Drive.

Additional improvements include:

Widening Terwillegar Drive/170 Street to six lanes (three in each direction), including new transit lanes.
A new separated shared-use path bridge over Anthony Henday Drive, connecting South Terwillegar to Windermere Boulevard, east of Currents Pointe.

Spring 2024 Project Update

The Province of Alberta announced additional funding as part of their 2024 budget to complete Stage Three of the Terwillegar Drive Expansion program. This stage will include various upgrades to ensure the area can accommodate all users safely and efficiently, now and in the future.
