Program Schedule


This program is funded by the City of Edmonton through the 2019-2022 Capital Budget and in partnership with the Government of Alberta.


A new plan to upgrade Terwillegar Drive to an expressway emerged during the initial planning study in mid-2017. The Terwillegar Drive Expansion Program was developed considering public input, direction from City Council, technical requirements and emerging plans and policies. Initially, a freeway was being developed for Terwillegar Drive.

Public Engagement

The City is committed to providing opportunities for anyone who is impacted or interested in the Terwillegar Drive Expansion Program to share input and contribute to the decision making.

The Terwillegar Drive Expansion Program, including Stage One, was developed considering the needs of area residents, businesses, community organizations and the public. Planning and design of the remaining stages will provide continued opportunities to learn about the projects, share input and contribute to the decision making.

Planning and design of each stage will balance public input, technical requirements and direction from City plans and policies. Additional opportunities to provide input and learn more about plans will be shared as the program advances.
