City awards Design-Build contract for Capital Line South LRT Extension project  

June 12, 2024

The City of Edmonton has awarded the Design-Build contract for Phase 1 of the Capital Line South Extension project from Century Park to north of Ellerslie Road.  

The City completed negotiations and formally awarded the contract to Capital Line Design-Build Ltd., a member of the Ledcor Group of Companies, with AECOM as their design partner. Over the coming months, the Ledcor team will begin detailed design with major construction along 111 Street anticipated to begin in 2025. Phase 1 of the project is a 4.5-kilometre, high-floor LRT extension along the west side of 111 Street and includes:

  • An LRT underpass at 23 Avenue
  • Two bridges (one across Blackmud Creek and one across Anthony Henday Drive)
  • Two stations (Twin Brooks station and Heritage Valley North station connecting to the Heritage Valley Transit Centre and Park and Ride)
  • An Operations and Maintenance Facility (south of Anthony Henday Drive)
  • Light Rail Vehicles (LRVs)

“Our city is experiencing rapid growth,” said Mayor Amarjeet Sohi. “As more people choose to call Edmonton home, we need to respond to the added pressure on our transportation network. The Capital Line South Extension will help improve sustainable mobility options as we grow to a city of two million by increasing ridership capacity and providing additional transportation options to communities in south Edmonton.”

Ledcor was selected as the preferred bidder in April 2024. Contract negotiations between the City and the preferred bidder occurred throughout April and May to ensure a robust project agreement was in place to protect Edmontonians’ interests and deliver value.

“The Capital Line South Extension project is a critical addition to our LRT network,” said Craig Walbaum, Acting Deputy City Manager, Integrated Infrastructure Services. “This project has been many years in the making and delivers on The City Plan goals of improving how we move people quickly, efficiently and sustainably along our transportation corridors. We look forward to working with Ledcor to bring this transformational infrastructure to life.”  

“Building on Ledcor’s 75-year legacy of serving Edmontonians, we are thrilled to be chosen by the City of Edmonton, with our design partner AECOM, to construct this vital new phase of public transit which will serve the city's growing population for many decades to come”, said Brad Mytko, SVP Infrastructure, Ledcor Group. “With passion and dedication, we will deliver a successful project, ensuring safety every step of the way.” 


In addition to expanding the city’s mass transit infrastructure, the Capital Line South Extension project will deliver a range of benefits locally, regionally and nationally. An economic assessment estimates the extension will generate 9,500 full-time jobs and $1 billion in wages and salaries through construction, operations and maintenance. The project is also projected to generate $88 million in tax revenue for Alberta and $211 million for the rest of Canada over 30 years. 

The $1.34 billion project has funding commitments from the Government of Canada, the Government of Alberta and the City of Edmonton. Over the coming months, the City will continue to advocate to funding partners for additional funding contributions to help ease future tax implications for Edmontonians.
