The City is developing a plan to upgrade Terwillegar Drive to an expressway.

Public Information Session - September 2019

Thank you to everyone who joined the September 18 public information session at St. Thomas More Parish to view the recommended concept plan. Project staff were available to answer any questions as residents learned more about the updates for transit users, motorists, pedestrians and cyclists, as well as next steps.

At the information session, a video was available that showed the new movement along Terwillegar Drive including the dedicated bus lane, motor vehicle lanes and shared-use path.

Project Update - March 2019

On Thursday March 7, 2019, Terwillegar Drive was named as one of the City projects awarded provincial funding through the Alberta Community Transit (ACT) fund. This contribution of $24.6 million provides funding for dedicated bus lanes on Terwillegar Drive and follows City Council’s decision in December 2018 to fund Stage 1 of the planned upgrades to Terwillegar Drive as a part of the 2019-2022 Capital Budget.

The City is now reviewing the concept plan for Stage 1, along Terwillegar Drive between Anthony Henday Drive and Whitemud Drive. Construction is currently anticipated to begin in the spring of 2020 or 2021. The recommended plan will improve vehicle capacity, reduce congestion and delays, and improve the accommodation for transit users, pedestrians and cyclists. Stage 1 upgrades include:

  • Widening Terwillegar Drive to 4 lanes in each direction between Anthony Henday Drive and Whitemud Drive: 3 lanes for motor vehicles and 1 for transit.

  • Intersection improvements

  • A shared-use path on the east side of Terwillegar Drive

  • Continued landscape naturalization on the corridor

When complete, the recommended concept plan will be shared with area residents, community leagues, stakeholders and the public for feedback and questions. This will also be an opportunity to see how input collected from the last phase of engagement, in late 2018, was used to refine the concept plan. More information on public opportunities to view the recommended plan will be shared in late summer 2019. Please sign up to receive future project notifications and updates.

About the Study

This study involves the development of an updated concept plan for the Terwillegar Drive corridor, between Whitemud Drive and Anthony Henday Drive. The study will recommend staging and provide cost estimates for consideration in upcoming capital budget cycles, including the 2019-2022 Capital Budget. The design of the first stage of improvements, which will be recommended as part of this study, is also included.

The project scope includes upgrades to the Haddow Drive, 23 Avenue, Rabbit Hill Road and Bulyea Road/40 Avenue intersections. The Anthony Henday Drive/Terwillegar Drive interchange is considered in a separate study.

The concept plan will build on previous studies and consider:

  • Anticipated traffic volumes in southwest Edmonton
  • Access to and from Terwillegar Drive
  • Off-site impacts
  • The environment
  • Community input
  • Roadway elements like noise walls and landscaping

All modes of transportation are being considered: vehicles, transit, trucks and active modes such as cycling.


Terwillegar Drive is a key north-south route that has exceeded its transportation capacity. It is also an important connector to 170 Street, which will become a future freeway from 41 Avenue to Leduc.

Terwillegar Drive was originally envisioned in the 1980's as a free-flowing road to accommodate travel demands within southwest Edmonton. The travel demand already exceeds capacity, causing users to experience delays, collisions and emit more greenhouse gases. The City’s Transportation Master Plan and Transportation Systems Bylaw 15101 both support the freeway conversion.

The ultimate goal is to accommodate all users locally and regionally, safely and efficiently, and to alleviate corridor congestion.
