Calgary City Council Approves $52M Revised Utility Relocation Budget for Green Line LRT Core

CALGARY, AB — The Calgary City Council approved a revised $52-million utility relocation allocation on Sunday afternoon to clear underground infrastructure ahead of major tunneling and guideway construction on the Green Line Light Rail Transit (LRT) project.

Utility Scope and Subterranean Civil Works

The funding adjustment authorizes the Green Line Project Board to complete critical relocations of high-voltage ENMAX electrical transmission ducts, ATCO natural gas mains, and City of Calgary deep stormwater trunks along 11th Avenue and 2nd Street SW in the Beltline and Downtown core.

The deep civil utility works will be executed using micro-tunneling and trenchless vacuum excavation to minimize roadway disruptions and preserve street-level access to local commercial businesses.

"Advancing deep utility relocations removes major subsurface construction risks before tunnel boring machinery arrives," Green Line Board leadership stated. "This step ensures the project maintains schedule certainty as we build Calgary's largest transit expansion."

Downtown Revitalization and Mobility

Once completed, the Green Line will connect southeast Calgary communities from Shepard to the downtown core, carrying an estimated 55,000 daily transit riders and connecting seamlessly with existing Red and Blue CTrain lines.

Downtown commercial business associations commended the city's commitment to staged nighttime construction and pedestrian corridor management during utility excavations.

Construction Milestones

Deep utility relocation contracts will wrap up by mid-2027, paving the way for guideway track installation and station platform construction.
