1 Street S.W. Corridor Improvements

Project update

The City of Calgary has awarded Marmot Construction Ltd. the contract to construct the improvements to the 1 Street S.W. Corridor. On-site construction is now expected to begin in the spring of 2017.

Over the winter, the construction team will develop construction plans and timelines. Once developed, this information will be shared with area stakeholders in 2017, in advance of work beginning.

About the project

In spring 2017, The City of Calgary will begin construction on the 1 Street S.W. Corridor Improvement Project.

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

  • wider sidewalks
  • more prominent bus stops
  • upgraded LED pedestrian and street lighting
  • additional bike racks and benches, and
  • 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 neighbourbood by attracting private developments, new businesses and more residents to the area.
