The City is continuing to develop options for improvements to Terwillegar Drive between Anthony Henday Drive and Whitemud Drive.

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 provide cost estimates for consideration in upcoming capital budget cycles.

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.

The study will recommend timing for interim and ultimate upgrades and project staging on Terwillegar Drive, including Bulyea Road/40 Avenue interchange.

The updated concept plan will be presented to City Council in Spring 2018. Following plan approval, preliminary engineering of the Bulyea Road/40 Avenue interchange is expected to be completed by Fall 2018.


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 1980s 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 freeway conversion goals are to accommodate all users locally and regionally, safely and efficiently, and to alleviate corridor congestion.

Project History

Public Engagement

November 2017-February 2018

The initial phase of engagement took place between November 2017 and February 2018.

The initial phase of public engagement was designed to gather priorities and perspectives for the City to consider in the validation and updating of the approved concept for Terwillegar Drive, and to gather feedback and perspectives on several high-level freeway configuration solutions and interchange design options. Engagement activities were conducted with community organizations, area residents, businesses, the public and commuters.

On January 24, the City held a public meeting to engage with residents, businesses, communities, and other stakeholders during the initial steps of the study. Attendance was high with over 480 interested citizens taking this opportunity to share priorities and perspectives for the study, and to share input on draft freeway design options.

A summary of the initial phase of engagement is presented in the attached What We Heard report.

What We Heard - January 24,  2018

August 2018

Following the February 27, 2018 Notice of Motion from City Council, the City is continuing to explore options for Terwillegar Drive which will improve congestion, maintain neighbourhood access and include opportunities for transit, pedestrians and cyclists.  

The next phase of public engagement will begin this Fall, when the City will reconnect with and update community organizations, area residents, businesses, and the public.  This will be an opportunity to provide feedback and perspectives on the next stage of planning and how it addresses priorities and concerns which were shared during the last phase of engagement in January, 2018, including:

  • Alleviating congestion

  • Maintaining existing direct access to Terwillegar Drive from adjacent neighbourhoods

  • Minimizing traffic congestion and diversions through area neighbourhoods

  • Improving connections for pedestrians, cyclists and transit

  • Minimizing noise and improving safety

Additional details about upcoming engagement opportunities will be shared as the plans evolve. Please sign up for project updates further down on this page to receive notifications of future updates and engagement opportunities.

January 2018

In fall 2017, the City of Edmonton initiated this study to update the approved concept plan for the Terwillegar Drive corridor, between Whitemud Drive and Anthony Henday Drive, considering current roadway standards, travel demand and population projections, and to advance preliminary engineering of the 40 Avenue interchange.
