August 15, 2025
The intersection of Stony Plain Road at 142 Street reopened to traffic on Thursday, August 14. With that, the City and Marigold Infrastructure Partners (MIP) are heading into the third and final phase of the Valley Line West accelerated roadwork plan for 2025.
Phase 3: Stony Plain Road at 149 Street (temporary partial closure)
Starting on or around August 15, the intersection of Stony Plain Road at 149 Street will be partially closed to traffic for approximately nine weeks. Similar to already-completed intersection work, overnight work will be required. Stony Plain Road at 142 Street will operate at full north/south capacity while the 149 Street intersection undergoes construction. More information on traffic and pedestrian impacts at 149 Street, including a map, can be found in MIP’s construction bulletin.
During this work, ETS Route 7 will detour from stops on 149 Street between Stony Plain Road and 107 Avenue. This route will detour using 149 Street, Stony Plain Road, 142 Street and 107 Avenue.
Road signage is posted near the affected intersection, providing advance notice to the public, commuters and businesses about upcoming traffic impacts.
“We know this work is disruptive, and we appreciate everyone’s continued patience as we head into the final stretch of the accelerated roadwork plan for 2025,” said Brian Latte, Director, Valley Line West. “The City is pleased with MIP’s momentum through the first two phases and expects that to continue until the end of the 2025 construction season.”
"As we move into Phase 3 of the accelerated work, we’re pleased to share that we’ve opened another intersection on schedule,” said Brendon Unrau, Superintendent with Marigold Infrastructure Partners. “We recognize how impactful this has been to the local businesses and residents, and we appreciate their cooperation over the last few months. We’re also fortunate to have a talented workforce, whose dedication and skill have made it possible for us to meet our ambitious timelines.”
Phase 1 update
104 Avenue between 105 and 121 Streets continues to be reduced to one lane in each direction. Overnight work on 104 Avenue is scheduled to continue until the end of November. MIP is making every effort to mitigate noise and other disruptions during nighttime hours.
Phase 2 update
The three-phased accelerated roadwork plan started in mid-April and is scheduled to continue until the end of November. The plan will reduce the overall duration of traffic restrictions by more than half, and take many of the roads into their final configuration by the end of 2025.
