A Highway Ready for the Future

With traffic volumes on Highway 1 projected to increase significantly. Envisioning an overpass that would support long‑term growth without compromising current mobility was vital. The Peter Lougheed Wildlife Overpass was conceived to span three lanes in each direction, enabling a future transition to a six-lane highway expansion.

From the outset, maintaining continuous traffic flow was a core design consideration. Highway 1 is a critical route for residents and tourists alike, with no viable detour options.

In partnership with DIALOG and construction partners, Egis helped shape a forward‑thinking solution that integrated roadway widening beneath the new structure.

By embedding traffic‑staging strategies into the design, the team envisioned a constructible approach that would keep two lanes open in each direction throughout construction—minimizing disruption while safeguarding mobility for all road users.

Resilience through solid road engineering

We worked with Dialog on the design and construction for the roadway beneath the twin arches, as well as on the roadside barrier protection required at the structure. This involved determining the road’s configuration, such as width and thickness of the pavement, as well as the design of shoulders, curbs, ditches, slopes, and drainage features.

We established the location, alignment, and elevation of the road according to design plans, and guided construction, verifying that work followed the design. This ensured road safety and functionality, as well as compliance with all standards and specifications.

During this process, Egis also assisted in the utility coordination to ensure safe construction above a major gas pipeline and telecommunication lines.
