The Green Line Light Rail Transit system will add 28 stations and 46 kilometres of track to Calgary’s existing LRT system. The line will run from 16th Avenue north to 126 Avenue SE, with an underground tunnel for the downtown portion of the system. The initial plans were for the Green Line to be constructed as a bus-only transitway, but was later converted to LRT as funding became available.

Since spring 2021 Green Line announced significant milestones for the project:

• The Alberta Provincial government completed a significant review of the project and announced their support for the Green Line LRT project with a revised procurement strategy. The Green Line will be built in two phases in a stage-gated approach, with the first phase building the LRT from Shepard to Eau Claire.

• On June 7, announcements were made by the Government of Canada and the Province of Alberta to reaffirm their support of the Green Line LRT project. Together with The City of Calgary, this secured the $4.9 billion funding committed by the three levels of government to bring the project to fruition.

• Green Line announced the start of the Beltline and Downtown Utility Relocation Project. This essential advanced work project will make way for the Green Line tunnel downtown by relocating underground utilities that would conflict with main construction. Work began in fall 2021 and is expected to continue through 2023.

• Updated Functional Plans for Green Line alignment, stations and bridges between the Elbow River and 16 Avenue N. were presented to the Green Line Committee and approved on May 19.
