Completion of two major projects shows big progress
Construction continues to advance across the Green Line LRT corridor, with two of the first major projects for Phase 1 now substantially complete.
The Blackfoot Trail LRT bridge and 78 Avenue LRT bridge were among the first major construction projects to get underway. Together, these projects will help carry the LRT line through southeast Calgary area while improving connections for people driving, walking and cycling.
Substantial completion is an important construction milestone, meaning the majority of work is finished, and the infrastructure is ready for its intended use. Some finishing work, such as landscaping, may continue afterward. While the two new LRT bridges are ready, tracks will be installed during future stages of construction to connect them to the broader alignment over the coming years.

A new landmark over Blackfoot Trail
The new Blackfoot Trail LRT bridge, located just south of Crossroads Market, was built to carry Green Line trains over Blackfoot Trail. It is one of the first visible pieces of LRT infrastructure completed for Phase 1 and was carefully constructed over the course of 12 months while maintaining traffic flow along one of Calgary’s busiest inner-city roadways.
The project included drilling concrete piles and constructing the bridge abutments, followed by the installation of prestressed concrete girders and construction of a concrete deck that will support both the future Green Line tracks and a multi-use pathway.

Bridging the way through Ogden
Nearby, the 78 Avenue LRT bridge is another key piece of the future transit system. Built alongside the recently completed 78 Avenue underpass, the bridge will carry Green Line trains over 78 Avenue SE as the alignment runs parallel to the Canadian Pacific Kansas City (CPKC) railway through Ogden.
Crews constructed foundations, retaining walls and abutments before installing seven precast concrete girders and pouring the bridge deck, putting the infrastructure in place for future construction through the area.

A visible sign of progress
While much of the work required to build a new LRT line happens below ground or behind the scenes, these projects offer a tangible look at the Green Line taking shape and demonstrate the progress being made on Phase 1 of Calgary’s largest infrastructure project.
As work continues across the alignment, Calgarians will begin to see more permanent pieces of the Green Line emerge from the ground.
Together, this work is laying the foundation for a modern, reliable transit system that will connect communities across southeast Calgary for generations to come.
