4 Street S.W. Underpass Enhancement

Project update

From September 2016 until early 2017, the east side pedestrian walkway will be closed to allow Enmax to complete their utility work prior to this project beginning. Once Enmax is finished, the general contractor will start the designed enhancements.

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 4 Street S.W. underpass is a priority for public realm improvements under the Council-endorsed “Downtown Underpass Urban Design Guidelines.” The underpass redesign is intended to address issues such as safety, connectivity, accessibility, vitality and beauty, and improving the overall comfort of pedestrians who use the underpass.

The City has completed planning and design for enhancements to the 4 Street S.W. underpass. The design developed by the marc boutin architectural collaborative (MBAC) integrates 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.

The enhancement project is part of a broader Centre City Underpass Enhancement Program underpass improvement 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.

Temporary Public Art

A temporary public art piece by Derek Michael Besant has been installed on site to help bring vibrancy to the underpass during the design and construction phases. Complementing the theme of connection, Besant’s piece captures notions of ‘place and personal context’ through a series of printed portraits and text representing a cross section of the community.

Impacts

This project will result in some underpass pedestrian and road restrictions and closures.

The east side pedestrian walkway is now closed to allow Enmax to begin their utility work which will continue into early 2017. Once Enmax is finished, the general contractor will begin the designed enhancements.

When the enhancements on the east side are completed and it is opened to the public, the west side walkway will close for construction.
