Project Overview

  • Existing intersections at 149 Street and 142 Street will be closed, and there will be no direct access to Yellowhead Trail from these streets. Road users will access Yellowhead Trail at the nearest interchange, at either 156 Street or St. Albert Trail.

  • All other access directly to Yellowhead Trail will be removed, including at 143 Street, existing service roads and existing business accesses.

  • One-way service roads will be built on the north and south sides of Yellowhead Trail to provide access to businesses and properties.

  • Changes and modifications made to 123 Avenue, 124 Avenue and 128 Avenue.

  • This project is anticipated to be complete by the end of 2023.

Construction Update - Spring 2023

Construction started in 2021 and is ongoing between 156 Street to St. Albert Trail. 

  • Road work is continuing on Yellowhead Trail and along 149 Street
  • Construction of the retaining wall, under the north end of St. Albert Trail bridge and under the north end of the 156 Street bridge, continues
  • Utility work is ongoing between 156 Street to St. Albert Trail
  • Building demolition is complete and construction of storm ponds at the southwest corner of Yellowhead Trail and 142 Street are continuing
  • Dovercourt noise wall replacement is complete

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.

Traffic Safety Measures

Recent construction activities along Yellowhead Trail have led to Dovercourt residents expressing concerns about speeding and shortcutting within the neighbourhood. Sherbrooke residents have also expressed concerns about speeding and shortcutting, resulting from future construction. To address these concerns, the City is implementing traffic calming measures, including new speed humps, raised crosswalks and a permanent traffic diverter at 124 Avenue.
