14 & 15 Avenue S Mobility Improvements

Project update - September 2021

In 2020, we set out to develop a concept design, based stakeholder feedback, analysis of data and technical considerations.

We conducted two phases of online and business engagement. Overall, Calgarians indicated very strong support for a protected wheeling facility on 15 Avenue S, and much of the feedback we heard also indicated support for 14 Avenue S reverting back to a two-way road. See the Engagement section for more information.

Our technical reviews included collision data reviews, policy alignment evaluations, traffic volume assessments and parking utilization studies for the 14 Avenue S and 15 Avenue S corridors.

The concept design is now complete. See the Concept design section to learn more.

Project background

As part of the 17 Avenue S.W. Construction Project, detours were required along 14 Avenue and 15 Avenue S. Both corridors were temporarily converted to one-way roads allowing people who drive to travel westbound along 14 Avenue and eastbound along 15 Avenue from 1 Street S.E. to 12 Street S.W.

Although parking was maintained on both sides of the road, the corridors were wide which can encourage speeding.

As a result of this change, stakeholders encouraged The City to improve the experience for those who walk and wheel through the community. The following changes were implemented:

  • One-way wheeling (bicycles, scooters, etc.) lanes, and buffered wheeling lanes where road widths allowed, were installed in the direction of traffic to provide connected and consistent wheeling facilities and to reduce the widths of the vehicular travel lanes.
  • Temporary traffic calming curbs were installed where crosswalks already existed to improve visibility and reduce crossing distances for people who walk and to encourage a reduction in traffic speeds as vehicles approach intersections.

We then set out to collect data, review operations, and gather feedback from Calgarians to develop a design recommendation for permanent infrastructure along the 14 and 15 Avenue S corridors.

For the 14 & 15 Avenue S Mobility Improvements project, we conducted two phases of engagement. Thank you to all who participated.

Phase 1: Identification

Between September 28 and October 19, 2020, Calgarians had an opportunity to provide input by telling us what is working well and what is challenging for those moving along the 14 and 15 Avenue S corridors (12 Street S.W. to 1 Street S.E.). We also asked what future improvements Calgarians would like to see. A summary of the feedback received is available in the What We Heard report.

Phase 2: Prioritization

We incorporated feedback received during Phase 1: Identification, along with technical analysis, to develop potential improvement options for the study area.

From January 11 to 31, 2021, Calgarians were invited to view these potential options and provide feedback. We received close to 1,100 individual contributions through the online portal, conducted two virtual sessions for area businesses and hosted several one-on-one meetings as requested by individual stakeholder businesses and organizations. Read the What We Heard report for Phase 2: Prioritization.

Concept design

Upon completion of stakeholder engagement, data analysis and technical work, we developed the following preferred concept design:

15 Avenue S

Includes a protected two-way wheeling lane on the north side of 15 Avenue S. This will require removal of parking on the north side of the road.

14 Avenue S

When the proposed changes are made to 15 Avenue S, 14 Avenue S will change back to a two-way road. Parking will be maintained on both sides of the corridor and the existing painted wheeling lane will be removed.

Future steps

Throughout this project, we have shared that the detailed design and construction are not yet funded.

As this unfunded status has not changed, the existing one-way configuration for 14 Avenue S and 15 Avenue S will remain in place for now, including the painted wheeling lanes and temporary traffic calming curbs.

We will explore funding opportunities for the detailed design and future construction. Once funding is secured, we will review and build on the existing engagement results and concept design work as required to confirm whether the recommended design still meets the needs of the community or if adjustments may be necessary.
