A summary of this project’s design and planning process to date is now available 4UE Schematic Design Report.

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, Derek’s piece captures notions of ‘place and personal context’ through a series of printed portraits and text representing a cross section of the community.

Project Overview

The City of Calgary has launched the planning, design and public art services for 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) has been 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.

Public engagement opportunities

MBAC and The City have been seeking the input of community and corporate stakeholders in setting a vision for the space and being active participants in the design process.

Please visit the project’s engage page for details on how stakeholder feedback has been used and next steps in the design process.
