1 Street S.W. Underpass Enhancement

Construction update

The work in the Underpass is complete. In the spring of 2016, ongoing minor maintenance work will take place, including another treatment of anti-graffiti coating.

This may require partial closure of the sidewalks to accommodate the work safely.

 

Project summary/background

The 1 Street S.W. underpass enhancement project is part of a broader underpass improvement program being implemented by The City of Calgary to improve the pedestrian environment and underpass connections between the Beltline and downtown communities. As part of the Centre City Underpass Enhancement Program, The City has been undertaking operational improvements to clean up and brighten existing underpasses.

The 1 Street S.W. underpass was prioritized for enhancement because it has the highest pedestrian use of all Centre City underpasses (9,500 pedestrians per day), was identified by community stakeholders as an important gateway connection, and in recognition of its significance as a heritage structure.

The original steel handrail was salvaged from the pedestrian walkways. The railing may be used to upgrade pedestrian railings at other CPR underpasses. Re-using the salvaged handrails should result in an estimated cost savings of $50,000.

Project scope

Stakeholders identified a number of safety and comfort issues to be resolved through the design, which included poor lighting, water drainage problems, uneven sidewalks and general deterioration of the underpass structure. Through a collaborative design process, enhancements were designed for both underpass structure and the pedestrian environment extending from 9 to 10 Avenue S.W. These include:

  • new sidewalks and guardrails
  • improved lighting
  • integrated art
  • painting of retaining walls and structure beams.

Transportation Infrastructure is responsible for managing this project.

Project timeline

  • January 2015: Start of construction
  • January 2016: Substantial completion

Project budget

  • $3.8 million

Funding sources include the Downtown Improvement Fund, Beltline Community Investment Fund, Transportation Capital Budget, and corporate and community donations from Canadian Pacific Railway (CPR), Fairmont Palliser Hotel, Victoria Park Business Revitalization Zone (BRZ), and Calgary Downtown Association.

Public engagement and Communications

Internal stakeholders representing eight Business Units and Calgary Police Service came together to build an understanding of the project and address opportunities, concerns and risks.

Through the engagement of both internal and external stakeholders, the consulting team of marc boutin architectural collaborative in partnership with el dorado and Lighting Design Innovations, developed this design for the 1st Street S.W. Underpass Project.

Adjacent property owners and businesses were engaged on design and continue to be informed as the project moves towards completion.
