General Project Update - What to Expect in 2025
Ledcor, the Design-Build contractor for the Capital Line South Extension, has started major construction along sections of 111 Street. A major lane shift at 111 Street and 23 Avenue was implemented in late 2024 to make room for the construction of the LRT underpass at the intersection. This lane shift is expected to remain in place for approximately two years.

Major construction along 111 Street will continue to increase throughout 2025. Drivers and residents will need to prepare for lane closures, detours and construction activities as Ledcor continues work along 111 Street, at Blackmud Creek, between 12 Avenue and 9 Avenue and at Anthony Henday Drive.
Summary of major anticipated construction activities in 2025
*timelines are subject to change, due to weather or other factors

  • Lane closures and traffic shifts to the west side of 111 Street between 12 Avenue and 9 Avenue (construction zone will be on the east side of 111 Street so Ledcor can build a new permanent roadway; this work will continue into the summer)
  • Off-peak lane closures and speed reductions on Anthony Henday Drive west of the 111 Street interchange

    • Staggered closures of 12 Avenue and 9 Avenue (east of 111 Street) so Ledcor can build a new permanent roadway. NOTE: 12 Avenue and 9 Avenue will NOT be closed at the same time. One access will always remain open.
  • Construction of approach sections for the Anthony Henday Drive LRT bridge
Late summer/fall 2025
  • Ongoing piling work south of 23 Avenue and 111 Street (for LRT underpass)

  • Occasional short-term closures of southbound lanes on the Blackmud Creek bridge (traffic detour will be in place)
  • Piling work near 9 Avenue for the Twin Brooks station
  • Traffic shifts to the east side of 111 Street onto the new permanent roadway
  • Esso gas station at 9 Avenue - permanent access closure to 111 Street entrance (9 Avenue entrance will stay open)
  • Structural steel installation for the Llew Lawrence Operations and Maintenance Facility
  • Piling work for the Heritage Valley North station (near the Heritage Valley Transit Centre and Park & Ride)
Individual construction notices, with further details, will be emailed to subscribers in advance of construction activities starting.

Please use caution through construction zones and allow extra travel time.
 
I really hope that bridge MUP pedestrian detour is carefully considered because that is a major route for anyone travelling N/S without any alterative route that is convenient.
 
I thought they widened Blackmud Creek Pedestrian Bridge for this reason? A few hundred extra metres and 8 extra metres of elevation, not great but not terrible.

The real crime is that the MUP is on the east side over the Henday, transitions to the west side over Blackmud, then back to the east side at 19/23 Ave.

I wrote the team about possibly adding a MUP to the side of 111 St between 9 Ave and 12 Ave at least, but they said there wasn't enough room with the road realignment -- though I believe they're adding driving lanes to 111 Street in that area. Sigh.

I hope the path over Blackmud Creek is improved, because the current one sees a lot of road slush get thrown onto it from the road in the winter. Not ideal. In the past two years they've dedicated a lane on the road as a detour, when doing work in the area, which has been nice. My fear is that longer term, they'll route active transport down Running Creek Road, which is a much steeper climb, and poor road surface.

The Edmonton special. All of 111th is like this. 87ave, lessard road/178st, etc.

All arterials should just be MUPs on both sides. Not sure why we’re alternating concrete sidewalks.
 

Latest Update:​

The City and Capital Line Design-Builder Ltd. formally entered into agreement in May 2024. Detailed design and major construction is underway. A major lane shift at 23 Avenue/111 Street intersection occurred in November 2024 to accommodate Stage 1 of LRT underpass construction. The contractor began concrete piling work in the area in early 2025 and this work will continue until Fall 2025. Tree removals in the Blackmud Creek area, concrete piling work at the Operations & Maintenance Facility, and 111 Street concrete median removals are underway. From Century Park station to 19 Avenue, along the west-side of 111 Street, crews have removed most of the berm to prepare for the eventual expansion of the road to accommodate the LRT tracks. This work is anticipated to occur until the summer of 2026. The procurement of LRV's (Light Rail Vehicles) is now underway and is expected to conclude in Q4 2025. The City will work with the contractor(s) to communicate the timing, duration and impact of construction to affected businesses and neighbourhoods, and mitigate impacts as much as possible.
 
Breaking ground on the Capital Line South LRT Extension
May 29, 2025

The City of Edmonton, along with the Honourable Devin Dreeshen, Minister, Transportation and Economic Corridors, Deputy Mayor Michael Janz, Councillor Jennifer Rice and Ledcor representatives Jennifer Villeneuve and Brian McPhee, officially celebrated the first year of major construction on the 4.5 kilometre Capital Line South LRT Extension.

“The expansion of the Capital Line South LRT marks an exciting milestone in Edmonton’s transit journey,” said the Honourable Eleanor Olszewski, Minister, Emergency Management and Community Resilience, and Minister responsible for Prairies Economic Development Canada. “This project will better connect neighbourhoods, bridge communities, and give Edmontonians faster, more reliable and more efficient ways to get around their city.”

“The Capital Line South LRT Extension is a vital project that will give Edmontonians a safe and efficient way to get to work, school and around their city. Alberta’s government is proud to invest $365 million to help make this project a reality and support the future of transit across the province,” said the Honourable Devin Dreeshen, Minister, Transportation and Economic Corridors.

“Today, we celebrate our continuing commitment to the people of Edmonton by providing them with a convenient, sustainable way to get to where they live, work and play. As transit ridership reaches historic levels, it is crucial that we build a city that is smooth to move,” said Deputy Mayor Michael Janz. “Great cities are defined by great public transportation systems. On behalf of the City of Edmonton, I thank the Government of Canada, as well as the Government of Alberta, for their funding, partnership and support for this transformational project. The Capital Line South will move Edmontonians of all ages, wages and stages of life and will define our great city for years to come.”

“Ledcor is thrilled to partner with the City of Edmonton, AECOM and our local contractors to construct this important transportation infrastructure that will serve our growing city for decades to come,” said Brad Mytko, SVP Infrastructure, Ledcor Group. “As members of the Edmonton community for over 75 years, we are proud to be part of this significant legacy project and are committed to prioritizing safety, protecting the environment and delivering the project successfully.”

Capital Line Design-Build Ltd., a member of the Ledcor Group of Companies, with AECOM as its design partner, has been awarded the Design-Build contract for Phase 1 of the Capital Line South LRT Extension project. The high-floor LRT extension will run along the west side of 111 Street from Century Park station to the future Heritage Valley North station at the Heritage Valley Transit Centre and Park & Ride.

Ledcor started major construction in early 2025. Construction is expected to take four to five years, followed by testing and commissioning. Phase 1 project highlights include:

  • LRT underpass at 111 Street and 23 Avenue
  • Two new bridges:
    • Blackmud Creek LRT bridge
    • Anthony Henday Drive LRT bridge
  • Two new stations:
    • Twin Brooks station
    • Heritage Valley North station (connects to the Heritage Valley Transit Centre and Park & Ride)
  • Llew Lawrence Operations and Maintenance Facility (south of Anthony Henday Drive)
  • New Light Rail Vehicles (LRVs)

The total project budget is $1.38 billion, and it continues to encourage a healthy labour market by generating jobs in design, construction and equipment. Albertans will benefit from Phase 1 with more than 3,500 jobs and more than $300 million in wages.
