Capital Line - South

Main page content begins here

Phase 1 of the Capital Line South extension began early works construction in 2022 and will continue throughout 2023. The competitive process to select a contractor to design and build the extension also launched in 2022, and we anticipate selecting the contractor in early 2024. Major LRT construction is anticipated to start in 2024.

Early Works Construction Along 111 Street

Throughout 2023, early works construction will occur along 111 Street for the future Capital Line South LRT extension. This work will prepare the alignment for the Design-Build contractor to begin major LRT construction in 2024. Stay up-to-date with information on early works construction activities.

May 16, 2023 City Council meeting

On May 16, the LRT project team discussed recommended project scope changes with City Council that are needed to remain within the approved project funding. Changes to the project scope were the result of significant economic pressures and market uncertainty that arose since the original project cost estimate was prepared in 2020. The following scope reductions/deferrals were recommended and approved by Council:

Heritage Valley North Station (changed from elevated station to at-grade station)
Heritage Valley Park & Ride (deferred the expansion (from 1100 stalls to 1900 stalls) to a future project)
LRV order (reduced to minimum service requirement and spares)
Operations & Maintenance Facility (reduced storage capacity for LRVs, and repurposed ROW equipment storage area for interim light maintenance)

On May 16, three motions were made at Council. Below is a high-level summary of Council’s decisions:

Twin Brooks station will get built.
Visual screen wall will not be made of concrete or brick.
- Project team is looking into whether or not there are alternative materials that are the same quality/cost of wood.
Project team will prepare a cost analysis for future construction of a grade-separated Ellerslie Road between 127 Street and 135 Street.
- This cost analysis is just for information, not for making a final decision about grade separation as Phase 1 of the project does not cross Ellerslie Road. A decision about grade separation at Ellerslie Road will be made at a future date that has yet to be determined.

Visual Screen Wall along 111 Street

On May 16, City Council defeated a motion that proposed a concrete or brick visual screen wall. This decision is consistent with the 2018 and 2022 noise studies, which indicated the average noise levels were below the 65 dBA threshold of the City’s Urban Traffic Noise Policy. The project team is now looking into whether or not there are alternative materials that are the same quality/cost of wood.

Construction Timeline
An exact timeline for visual screen wall construction is not known, however, construction is unlikely to occur in 2023. The City knows there is a desire from the community to have the wall built before major construction starts along 111 Street in 2024

Twin Brooks Station - Capital Line South Extension Public Survey

Between December 14, 2022 and January 22, 2023, the City of Edmonton gathered public feedback and provided education through a survey about the Twin Brooks station that is approved as part of Phase 1 of the Capital Line South LRT extension project. The survey closed with a total of 1,788 respondents and over 2,600 comments were received in the open-text questions. The City has compiled the feedback from the survey and has composed it into a summarized report.

Procurement Process to Select the Design-Build Contractor

In June 2022, a Request for Qualifications (RFQ) was issued to identify and shortlist qualified bidders to design and build this LRT extension. Two bidders were shortlisted. The Request for Proposals (RFP) was issued to the two shortlisted bidders on March 31, 2023, with the selection of the Design-Build contractor to occur in early 2024.

About The Project

Build Phase

The extension will be completed in two phases. Phase 1 will extend the line from Century Park to just north of Ellerslie Road, and Phase 2 will extend from Ellerslie Road to Allard/Desrochers. Concept design for Phase 2 has been advanced.

Capital Line South Phase 1 (Century Park to just north of Ellerslie Road) is a 4.5 km long, high floor LRT and includes:

An underpass at 23 Avenue
Bridges crossing Blackmud Creek and Anthony Henday Drive
A new operations and maintenance facility south of Anthony Henday Drive
A neighbourhood LRT station at Twin Brooks (which will be smaller in size compared to a multi-modal transit station like Century Park)
A multi-modal LRT station connecting to the Heritage Valley Park & Ride just north of Ellerslie Road
