The City of Calgary announced that following evaluation of the Request For Proposal, the Green Line Board has selected Graham Infrastructure LP to construct the 78 Avenue S.E. Grade Separation and Ogden Pedestrian Tunnel Project.

Before building the Ogden LRT station and tracks, the 78th Avenue Project will complete vehicle and pedestrian tunnels under the Canadian Pacific Kansas City Railway (CPKC) railway corridor to enhance mobility and pedestrian safety around the future Green Line LRT Ogden Station. (The Green Line LRT is No. 16 on ReNew’s 2023 Top100 Projects report).

With approximately 26 trains per day operating on CPKC’s main line, this complex enabling works project will reduce project and schedule risk as Green Line prepares for main LRT construction. Once the tunnel at 78 Avenue S.E. is complete and open to traffic, the vehicle crossing at 69 Avenue S.E., east of Ogden Road, will be permanently closed.

“Green Line has prioritized opportunities that advance construction, reduce risk, and support local job creation. Partnering with Graham to deliver this critical project speaks directly to this commitment,” said Darshpreet Bhatti, CEO, Green Line LRT Program.

With construction beginning shortly and extending through to summer 2025, Green Line will work closely with the Ogden community to mitigate impacts, as best as possible. Public information sessions begin on June 13, 2023, with details available at: 78 Avenue Project | Green Line LRT (

The start of the Implementation Phase and main construction remain on track to begin in 2024.
