The City is expanding Terwillegar Drive beginning in fall 2020.

Project Update - September 2020

Funding

On July 8, 2020, the Government of Alberta announced funding for expanding Terwillegar Drive. The investment provides construction funding towards the south portion of Stage 1, from Anthony Henday Drive to Rabbit Hill Road, the shared-use path on the east side of Terwillegar Drive, the pedestrian/cyclist bridge and Stage 3.

With this announced funding and previously approved funding in the 2019-2022 Capital Budget, all 3 stages of the Terwillegar Drive upgrades can advance to construction, improving vehicle capacity, reducing congestion and delays and improving the accommodation of transit users, pedestrians and cyclists. 

Stages

Following the funding announcement, the City is continuing to refine the staging plan for the expansion of Terwillegar Drive as planning and design progresses. The City is continuing  to advance planning and design of Stages 1 and 2 and is currently conducting a technical study to further refine the concept plans for Stage 2. 

A study has also been initiated to develop a concept plan for the pedestrian/cyclist bridge over Whitemud Drive. After analyzing public input from previous engagement, upcoming public engagement will provide opportunities to refine the bridge concept. Preparations are underway to begin the planning and design of Stage 3.

Timelines

Site preparations for the construction of Stage 1 begin in September 2020 between 40 Avenue and Rabbit Hill Road. The preconstruction activities will take place until late fall 2020. Construction on Stage 1, between Rabbit Hill Road and Whitemud Drive, will begin spring 2021. 

Preliminary design of Stage 2 is expected to start this fall. More information on public opportunities to learn about the plans for Stage 2 will be shared in the coming months.

The next phase of engagement on the pedestrian/cyclist bridge is expected to commence this fall. More information on public engagement opportunities will be shared in early fall.

More information on public engagement opportunities will be shared in early fall. Please sign up to receive future project notifications and updates.

About the Program

The program includes 3 stages of upgrades to accommodate all users including motorists, transit users, pedestrians and cyclists.

Planning, design and construction is being implemented through a staged approach to support the efficient delivery of the program and minimize construction impacts. The goals of the program are to alleviate congestion and accommodate all users safely and efficiently. 

Planning and design will balance public input, technical requirements and direction from City plans and policies. Additional opportunities for community organizations, area residents, businesses, and the public to provide input and learn more about plans will be shared as the program advances.

Program Stages

Stage 1: Anthony Henday Drive to Whitemud Drive
  • Widening Terwillegar Drive to 4 lanes in each direction between Anthony Henday Drive and Whitemud Drive (3 lanes for motor vehicles and 1 dedicated lane for transit)

  • Intersection upgrades, enhanced bus stops, and a shared-use path on the east side of the corridor

Stage 2: Interchange Upgrades, Rainbow Valley Bridge & Pedestrian/Cyclist Bridge
  • Whitemud Drive/Terwillegar Drive interchange improvements

  • Whitemud Drive widening and associated upgrades

  • Rehabilitation and widening of the Rainbow Valley Bridges

  • Pedestrian/cyclist bridge over Whitemud Drive at 142 Street

Stage 3: Anthony Henday Drive Interchange Upgrades
  • Interchange upgrades, including an additional northbound bridge, ramp improvements, active mode improvements and transit priority measures

  • Terwillegar Drive/170 Street widening

Background

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 connection from 41 Avenue to Leduc. 

Terwillegar Drive was originally envisioned in the 1980s as a free-flowing road to accommodate travel demand within southwest Edmonton. The travel demand already exceeds capacity, causing users to experience delays, collisions and emit more greenhouse gases. 

A new plan centered around upgrading Terwillegar Drive to an expressway emerged during a conceptual planning study initiated in mid 2017. The program was developed considering public input, direction from City Council, technical requirements, and emerging plans and policies. In October 2018, Edmonton’s Urban Planning Committee provided direction to advance the expressway plan for Terwillegar Drive. 

All 3 stages of the program are now funded. In fall 2019, City Council approved funding for the north portion of Stage 1 from Rabbit Hill Road to Whitemud Drive and Stage 2 (excluding construction of the pedestrian/cyclist bridge). On July 8, 2020, the Government of Alberta announced additional funding towards construction of the south portion of Stage 1, from Anthony Henday Drive to Rabbit Hill Road, the shared-use path on the east side of Terwillegar Drive, the pedestrian/cyclist bridge (Stage 2), transit priority measures (Stage 2) and Stage 3.
