Yellowhead Trail - 156 Street to St. Albert Trail

Construction Update - Winter 2024

Construction on the 156 Street to St. Albert Trail segment of the Yellowhead Trail Freeway Conversion is complete.

Drivers will experience:

Three continuous lanes along Yellowhead Trail in both directions with an increased speed limit of 80 km/hr (from the previous 70 km/hr limit).
New, dedicated, one-way service roads in the eastbound and westbound directions for improved access to St Albert Trail, 142 Street, 149 Street, 156 Street and businesses and adjacent communities.
The removal of signalized intersections at 142 Street and 149 Street.

Additional upgrades include new sidewalk connections along both sides of Yellowhead Trail, new LED streetlighting, a new concrete sound wall installed along the Dovercourt community, and landscaping, including improved underground drainage to enhance road conditions during heavy rainfall.

Overhead signs will continue to be installed periodically until early 2025. Please follow construction signs and speed limits to ensure safety of the workers present.

156 Street Project History

Construction Update - Spring 2024

Construction started in 2021 and is ongoing between 156 Street to St. Albert Trail. The following work is in progress:

Traffic accommodations are currently in place:

New Eastbound Service Road, accessed from eastbound Yellowhead Trail, west of 149 Street, provides access south of Yellowhead Trail to 149 Street, 142 Street, St Albert Trail and south businesses.
New Westbound Service Road, accessed from westbound Yellowhead Trail, at 143 Street and 147 Street, provides access north of Yellowhead Trail to 143 Street, 149 Street, 156 Street and north businesses.
Two lanes of traffic along Yellowhead Trail will be open during peak hours. There will be times overnight that only 1 lane in each direction will be open on Yellowhead Trail. The speed limit may be reduced to 40km/hour in construction zones and we ask the public to be mindful of signs and construction crews as they travel through the area.

Dovercourt and Sherbrooke Traffic Safety Measures

Construction activities along Yellowhead Trail have led to Dovercourt and Sherbrooke residents expressing concerns about speeding and shortcutting within the neighbourhood.

To address these concerns, the City is implementing a comprehensive traffic management plan.

October 2015 - Final Concept Plan

The final concept plan was presented to the Transportation Committee on October 7, 2015.

January 2015 - Project Update

The City focused on refining the preferred concept plan for Yellowhead Trail at 149 Street. The preferred concept includes one-way service roads parallel to Yellowhead Trail on the north and south sides. There is no connection proposed for 149 Street across Yellowhead Trail. The City will evaluate the changes that will be required to the surrounding road network to address changes in travel pattern as a result of the proposed plan.

January 2014

The City completed the final stages of a significant public engagement process that resulted in the development and refinement of a preferred option for freeway operation of Yellowhead Trail at 149 Street.

Public Involvement Report
The public engagement process included an Open House in June 2012 with a second open house in September 2013, 11 key stakeholder meetings, discussions with internal and external stakeholders such as CN Rail and utility companies, information bulletins to the community and the establishment of a Stakeholder Input Group (SIG).

This group of area stakeholders worked with City planners to develop ideas for converting Yellowhead Trail at 149 Street to a freeway operation, while retaining reasonable access to the adjacent businesses and the Dovercourt community. The stakeholder group helped to identify and develop:

Issues and constraints
Evaluation criteria and their relative weighting
Interchange and preferred access arrangements

Over the course of several workshops, the stakeholders helped to evaluate and reduce the total number of alternatives.

After significant development and evaluation of alternatives, the City arrived at a recommended configuration for the area based on input received from internal and external stakeholders, as well as Transportation Committee.

This preferred option includes one-way service roads parallel to Yellowhead Trail on the north and south sides. There is no connection proposed for 149 Street across Yellowhead Trail.

September 2013 - Public Meeting

On Tuesday September 17, the City of Edmonton hosted a public meeting to provide information on the recommended concept for free flow operation of Yellowhead Trail at 149 Street.

During the Open House, the public were invited to view the presentation boards and maps, ask questions of our project staff and pick-up project information material.

July 2013 – Transportation Committee

Two freeway options were presented to City Council on July 10, 2013; Freeway Strategy A which includes a ¾ diamond, grade separated interchange and Freeway Strategy B that which includes one-way service roads with right-in/right-out access north and south of Yellowhead Trail as well as improvements to parallel routes on 128 Avenue, 123 Avenue and 124 Avenue.

October 2012 – Project Update

An information bulletin was mailed out to community groups and businesses adjacent to the intersection . The bulletin provided an update on feedback received during the June 2012 Open House and requested comments or suggestions from the public.

June 2012 - Public Open House

A public Open House was held in June 2012 to introduce the project and provide background information. Attendees had the opportunity to learn more about the project and provide comments. Thanks to residents and community stakeholders who attended the June 13, 2012 meeting on the 149 Street Interchange at Yellowhead Trail.
