The initial investment in the Green Line will be the foundation for future extensions to the north and southeast. Stage 1 will feature:

  • 20 km of LRT track
  • 14 stations
  • 8 bridges (Elbow River, Blackfoot Trail, Highfield Blvd, 46 Avenue SE, Deerfoot Trail, Bow River, 78 Avenue SE and 90 Avenue SE)
  • 1 km of elevated track between Inglewood/Ramsay to 26 Avenue stations
  • 3 park and ride facilities with a total of 1800 - 1900 stalls (Lynnwood/Millican, Douglas Glen, and Shepard)
  • 3 tunnels (CN/Highfield; Ogden Road SE and Barlow Trail/114 Avenue SE)
  • 4 km Centre City tunnel from 20 Avenue N to Macleod Trail
  • 1 light rail vehicle (LRV) Maintenance and Storage Facility north of 126 Avenue SE (Shepard)
  • Approximately 70 low floor vehicles
  • $4.65 billion capital construction cost

Southeast construction work

In December 2016, the Federal and Provincial Government committed more than $250 million dollars to fund a series of Enabling Works for the Green Line LRT for 2017/18. Projects such as utility relocations, land preparation, environmental remediation and transit improvements can require a lot of time and resources. Doing these types of projects proactively will help in managing project timelines and risks, and will allow future Green Line construction to occur more efficiently. More details are available on projects that are expected to begin in the next year. Detailed discussions with communities will be initiated in the coming months, as construction timelines are refined.

Stage 1 - Building the Core

The first stage of construction for Green Line LRT is recommended to extend from 16 Avenue N (Crescent Heights) to 126 Avenue S.E. (Shepard). This will be the longest segment of LRT ever constructed at one time in Calgary’s history.

Stage 1 construction of the Green Line will support community development, provide greater transportation choices to access Calgary’s community amenities and resources, and is essential to supporting Calgary’s growth.

Stage 1 construction will:

  • Facilitate future extensions by building the most complex and costly piece first (downtown tunnel). This will allow future extensions to the north and southeast to occur incrementally, as funding becomes available.
  • Be construction-ready, meaning The City has already completed much of the design and is in the process of acquiring the land required to build in these areas.
  • Establish a strong foundation of LRT service and supporting facilities (such as the maintenance and storage facility, park and ride lots, and transit hubs) required to operate the new line.
  • Stimulate the economy by creating thousands of construction, professional and administrative jobs over the 10 year construction period.

Opening day benefits of stage 1 construction:

  • Carry 60,000 to 65,000 Calgarians.
  • Serve all Calgarians by connecting to major activity, employment and industrial centres outside the downtown core (Quarry Park, Douglas Glen, South Hill) and over 60 existing community services such as recreation centres, parks and libraries.
  • Connect over 2,300 existing affordable housing units.
  • Support business and employee travel choices for 191,000 existing jobs.
  • Reduce greenhouse gases by 30,000 tonnes, the equivalent of 6,000 vehicles being taken off the road on opening day.

Construction schedule

A construction schedule will be developed once funding commitments from all three levels of government are in place. Stage 1 is projected to begin construction in 2020, pending approvals and funding, and is anticipated to open in 2026.

Future vision

The full 46 km Green Line LRT from 160 Avenue N to Seton in the southeast will be constructed in stages over a number of years, as funding becomes available. Planning for the full Green Line will continue, including property acquisition, Transit Oriented Development (TOD) planning, and planning the transportation network.​​​​​​​​​​​​
