The City is preparing to convert Terwillegar Drive into a freeway between Whitemud Drive and Anthony Henday Drive.

The concept will include recommended staging and timing of upgrades to accommodate increased traffic, reduce congestion and improve safety.

As part of this study, the City anticipates to complete preliminary design of a grade separation at Bulyea Road/40 Avenue.

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.

Preliminary engineering for Bulyea Road/40 Avenue Interchange


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.
