The Calgary Green Line LRT project has undergone significant changes since its initial approval in 2017. Originally planned as a 20-kilometre line costing $4.65 billion, the project has faced delays and cost increases. After multiple revisions, including changing from a tunnel to a bridge over the Bow River, the current plan approved in July 2024 is for a downsized 10-kilometre Phase 1 at a cost of $6.248 billion. This shortened line, running from Eau Claire to Lynnwood/Millican, reflects budget constraints and inflation, with six planned stations cut. The city has increased its funding share to $2.9 billion, while also allocating $1.45 billion to other major projects including a new Flames arena, BMO Centre expansion, and Arts Commons building.​​​​​​​​​​​​​​​​
