78 Avenue Grade Separation and Ogden Pedestrian Tunnel

July 1, 2025

Station: Ogden

Status: Completed

Type: Stations

The 78 Avenue Grade Separation and Ogden Pedestrian Tunnel was a large-scale early works project

Scope of work

The overall scope of work included constructing a pedestrian tunnel at 72 Avenue SE, a vehicle underpass at 78 Avenue SE, and upgrading a portion of 78 Avenue from Ogden Road east to the Canadian Pacific Kansas City (CPKC) rail line, including new utilities and roadworks to support long-term infrastructure needs. On the east side of the embankment, a new roundabout connecting to Ogden Dale Road was also constructed to create a new entrance in and out of the industrial area.

As an early works project, this work enhances transportation and pedestrian safety in the area and supports the future construction of the Green Line SE Project.

The Green Line alignment will run parallel and west of the current CPKC rail line in Ogden, with its own bridge to cross 78 Avenue SE. The Ogden Station will be located near 72 Avenue SE.

78 Avenue SE now connects to a roundabout built on the east side of the underpass. This roundabout allows trucks travelling on Ogden Dale Road SE to remain on designated truck routes without entering the community.

Other work included installation and upgrades of stormwater infrastructure and other utility installations, including a manhole at Ogden Road and 78 Avenue SE, and landscaping and sidewalk improvements.

Once the underpass is open towards the end of July, , 78 Avenue SE will become the new connection between Ogden and the industrial area east of the CPKC rail tracks. However, 78 Avenue SE will not be designated as a truck route.

72 Avenue area

A pedestrian tunnel near 72 Avenue SE has been built to connect the future Ogden Station to Ogden Dale Road SE. This tunnel will remain closed until the future Ogden station opens. The tunnel is currently fenced for safety reasons.

69 Avenue

Once the underpass at 78 Avenue SE is open to traffic, 69 Avenue SE at the CPKC tracks will be closed permanently.

78 Avenue SE will become the new connection between Ogden Road and Ogden Dale Road SE.

Piling in action in Ogden in June 2024. The piling rig uses an auger to dig deep into the ground (around 20 metres). These piles then form the foundation structure for the tunnel that will be built at 78 Avenue SE on the east side of the Canadian Pacific Kansas City (CPKC) rail tracks.
A loader is used in conjunction with the piling rig to remove the dirt that the rig brings up from deep in the ground.

A large rebar cage is fabricated on site and then lifted into the piling hole to add structural support to the concrete that gets poured in afterwards.
The rebar cage is placed down into the hole.
It takes a lot of coordination to safely get the rebar cage placed correctly so it can go down into the hole.
