4 Street S.W. Underpass Enhancement

Project update - December 13, 2018

Work continues on the west side of the underpass with the anticipated project completion in February 2019.

 

About the project

Situated between 8 Avenue and 10 Avenue, the 4 Street S.W. underpass is a main gateway and key corridor for pedestrians and vehicles moving between the Beltline and downtown core, servicing over 8,000 pedestrians each day.

The project includes new sidewalk concrete and retaining wall repairs, new handrails, concrete framework for new stairs connecting to 9 Avenue overpass, improvements to the 3 Street turnoff for increased pedestrian safety, and upgrades to the ENMAX underground ductbanks.

The project design was developed by the Marc Boutin Architectural Collaborative (MBAC) and integrates architecture, infrastructure and artwork into the redesign of the space. Internationally acclaimed artist Krzysztof Wodiczko is also part of the design team.

The enhancement project is part of a broader Centre City Underpass Enhancement Program ​being facilitated by The City to improve the pedestrian environment and underpass connections between the Beltline and downtown communities. The City has been undertaking operational improvements to clean up and brighten other existing underpasses including 1 Street S.W., 5 Street S.W. and 8 Street S.W.
