Check out this map showing the St. Albert Trail to 97 Street study area.

Proposed Changes

The concept planning study for this area will consider:

  • Removal of traffic signals at 127 Street, 124 Street, 121 Street and 107 Street 

  • Removal of direct access to Yellowhead Trail, including at 130 Street, 126 Street and CN Rail

  • Alternate access to 130 Street, 126 Street, 124 Street as well as 107 Street

Project Update - February 2021

The Hybrid Option Concept Plan Overview

Detailed Concept Plan

The Hybrid Option Concept includes:

  • Two new interchanges at 127 Street and 115 Street

  • A connection from 107 Street to the 115 Street interchange to provide all-directional access to Yellowhead Trail

  • New service roads to manage traffic flow into residential and business neighbourhoods in the west part of the study area

The concept plan does not require the purchase of any residential properties, however the City will need to buy some commercial land for this project.

How the Concept was Selected

Three design options were presented during Phase 2 engagement.

Feedback from Phase 2 indicated that Option 1 (service road) and Option 2 (conventional interchange) each had some desirable features. Each option also had features that the public raised concerns about.

It was noted that Option 1 (service road) had a lack of connection to Yellowhead Trail due to the long stretches of service roads. In Option 2 (conventional interchange) there were concerns with the safety and efficiency of the back to back merges between St. Albert Trail and 127 Street.


We created a hybrid option by combining the west section of Option 1 with the east section of Option 2. We then evaluated each of the 4 different options using project specific criteria.

During this evaluation process, Option 3 (127 Street Overpass/121 Street interchange) was eliminated. The technical analysis of Option 3 matched the concerns we heard from the public, and it was clear that Option 3 would not meet the project objectives.

Final Selection

The hybrid option was selected as the concept plan. It was one of the most cost-effective options evaluated, providing safe and efficient merging on Yellowhead Trail along with better connectivity. The hybrid option has been further refined to address additional feedback from Phase 2.

Phase 3: Concept

Public and stakeholder feedback will be used to refine the concept as it moves into the next phase of design. Construction is planned to begin in 2023 and be complete in 2027.

Phase 2: Explore and Refine Options

Public and stakeholder feedback from Phase 2 in fall 2020 will be used alongside a detailed technical analysis to develop a recommended concept plan by early 2021. Construction is planned to begin in 2023.

Phase 1: Identify Values, Issues and Ideas

Two engagement events were held in November 2019. Learn more about what we heard from engagement participants.

Public Engagement

The City values public input and recognizes its importance in identifying the needs of all Yellowhead Trail road users, area residents and businesses. Each segment of the Yellowhead Trail Freeway Conversion Program is being built to balance the roadway requirements with community, business and commuter needs.
