1 Street S.W. Corridor Improvements

Join our mailing list

Project update – June 9, 2017

Significant progress has been since work started in early May. The first major stage of improvements between 10-12 Avenues is nearing completion. The next stage for construction is between 13-17 Avenues.

Improvements along the 1 Street corridor are taking place in stages with the goal of minimizing impacts to businesses, residents, pedestrians and motorists.

View a detailed list of current and upcoming roadway and sidewalk detours and parking restrictions.

The location and design of some bus stops will be modified through this project to improve Calgary Transit customer service and safety. During construction some road closures may temporarily impact Transit operations. Information on any Transit detours will be posted at bus stops in advance of the detour and by Calgary Transit via social media.

Project completion is anticipated to be fall 2017.

Take note that to help visitors and Beltline residents navigate around work zones related to the 17 Avenue S.W. Construction project, 14 and 15 Avenues have been turned into temporary one-way streets.

About the project

This project will improve the streetscape for pedestrians and transit riders by providing:

  • wider sidewalks
  • prominent crosswalks
  • upgraded LED pedestrian and street lighting
  • additional bike racks
  • increased number of on-street parking spaces
  • new tree plantings.

The design builds on the existing character of the blocks located between 12 and 14 Avenues, extending the streetscape design along the full length of the corridor – from the CPR underpass to 17th Avenue. The improvements are intended to create a safer, more comfortable and inviting environment for the thousands of pedestrians and transit riders that travel along this corridor each day.

Project summary/background

This project supports the fundamental principles of Calgary’s Centre City Plan, which places a higher priority on pedestrian and transit mobility, emphasizes the creation of great streets and places for people, and aims to build liveable, inclusive and connected neighbourhoods.

In 2003, The City implemented the first phase of public realm and streetscape improvements along 1 Street S.W. between 12 and 14 Avenues, with the intent of supporting the revitalization of the area. Since that time, significant private investment has been made in this area through residential and non-residential developments.

In 2016, The City completed the second phase of improvements to the 1 Street S.W. corridor through work on the 1 Street S.W. CPR underpass enhancement project, which was designed to benefit the nearly 10,000 pedestrians who travel though the underpass each day.

This project implements the final phase of improvements to the corridor by extending the streetscape character first established in 2003 along the full length of the corridor. It is anticipated that The City’s investment along this corridor will help with the continued revitalization of the neighbourhood by attracting private developments, new businesses and more residents to the area.
