4 Street S.W. Underpass Enhancement Project

Latest news

Construction has now begun on this project which is anticipated to be completed by Fall 2018.

Currently, the east pedestrian walkway is closed. The sidewalk was removed this past winter as part of an Enmax project to rebuild an electrical conduit that runs beneath the walkway. The east walkway will remain closed until the sidewalk is rebuilt and enhancements are completed. Once the east side reopens to the public, the west side walkway will close for construction.

Project Overview

Th​e City of Calgary has begun construction on the 4th Street S.W. Underpass Enhancement Project.

Situated between 8th Avenue and 10th Avenue S.W., the 4th 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 4th Street S.W. underpass has been identified as a priority for public realm improvements under the Council-endorsed “Downtown Underpass Urban Design Guidelines.” The underpass redesign intends to address issues such as safety, connectivity, accessibility, vitality and beauty, improving the overall comfort of pedestrians who access the site.

The marc boutin architectural collaborative (MBAC) was awarded the tender to develop a schematic design for the underpass that will integrate architecture, infrastructure and artwork into the redesign of the space. Internationally-acclaimed artist Krzysztof Wodiczko is also part of this design team charged with reinvigorating the underpass.

This enhancement project is part of the broader Centre City Underpass Enhancement Program, which aims to improve the pedestrian environment and connections between the Beltline and downtown communities, including cleaning up and brightening existing underpasses.
