12 Avenue South Improvements

12 Avenue South Improvements

Project update

Work on Phase 1 and Phase 2 was completed in October 2019. Several improvements made along the corridor included:

  • Extending the dedicated lane for people cycling from 11 Street to 15 Street S.W.
  • Adding bicycle turn boxes at 12 Avenue and 11 Street S.W.
  • Improving travel time for drivers by providing three uninterrupted driving lanes for morning rush hour.
  • Removing the rush hour parking restriction on the north side of 12 Avenue between 15 Street and 16 Street S.W.
  • Providing a loading stall on the east side of 12 Street S.W., just north of 12 Avenue S.W.

The initial Phase 3 design and What We Heard engagement feedback was presented in a public information session at the Sunalta Community Hall on Dec. 11, 2019.

In 2020, the project team looked at ways to refine the Phase 3 design to preserve some of the on-street parking along 12 Avenue South while keeping the intent of the project and providing more travel options. The project team is currently completing the technical work for the Phase 3 design and will share the design with the community later this year.

Overall improvements as part of Phase 3 construction include:

  • Extending the two-way cycle track facility on the north side of 12 Avenue S.W. from 15 Street to 19 Street S.W., and then on the east side of 19 Street S.W. from 12 Avenue to 10 Avenue S.W.
  • Providing a dedicated cycling facility for all ages and abilities, separated from vehicular traffic by parking curbs and/or flexible delineators.
  • Using the on-street cycle track to physically narrow the roadway reducing vehicle speeds and improving safety of pedestrians/cyclists.
  • Retaining one vehicle lane on 12 Avenue S.W. between 15 Street and 19 Street S.W. to preserve some of the on-street parking on 12 Avenue S.W.
  • Additionally, one southbound vehicle lane is retained on 19 Street S.W. from 10 Avenue to 12 Avenue S.W., with parking consolidated to the west side of 19 Street S.W.
  • Improving sidewalk ramps at most intersections to line up with pathway routes crossing the street.
  • Removing two right hand turning lanes to reduce turning speeds, shorten pedestrian crossing distances and improve sightlines.
  • Adding a new traffic signal at 10 Avenue and 19 Street S.W. to facilitate crossings at 10 Avenue S.W.
  • Surface overlay repaving along 19 Street S.W. is planned for 2021.

Construction of Phase 3 is currently anticipated to begin in 2021.

Engagement summary

Public input about the 12 Avenue South Improvements project was collected in Spring 2019. In total, the project team talked to 260 people and over 60 businesses through the open house events, door knocking sessions and online. Thank you to those who provided input. Information from the previous engagement session is available.

Next steps

Over the next 18-months, the new section of open cycle track will be monitored and adjustments may still be made.

Work on 12 Avenue South is being done in three phases:

Fast Facts:

Frequently Asked Questions


When does construction start?

Construction for Phases 1 and 2 was completed in 2019. Phase 3 construction is anticipated in 2021. Prior to construction, the project team will provide project updates via email and on this page (

Why is Phase 3 construction slated for 2021?

Currently, the project team is doing some additional technical work on the Phase 3 design to address concerns in the community regarding availability of on-street parking.

The revised design will retain on-street parking availability for portions along both sides of 12 Avenue S.W. while keeping the intent of the project and providing more travel options.

As the technical work is still underway and we plan to share the revised design with the community prior to implementation, construction is now anticipated for 2021.

Will access to 12 Avenue S.W. be closed at any time during construction?

12 Avenue South will remain open for the duration of the project. We will make every effort to minimize impacts during construction and will notify impacted residents prior to any disruptions due to construction.


How will parking and loading change on the corridor?

To allow for smooth and predictable traffic flow, on-street parking on the south side of the roadway will remain. Some of the on-street parking on the north side will also remain, however, short sections will remain as Loading Zones to ensure emergency services can continue to have access to both sides of the street The exact configuration is currently being designed and we will share plans with the community later this year.


What engagement was done for this project?

Public input about the project was collected using the following engagement and community outreach activities:

  • Three door knocking sessions with businesses located on 12 Avenue S.W. between 4 Street and 16 Street S.W. throughout May 2019.
  • Online, through the Engage portal from May 28 – June 11, 2019.
  • Two open house events including:
    1. Connaught School (1121 12 Ave S.W.) on May 28, 2019, from 7 – 9 p.m.
    2. Sunalta Community Association (1627 10 Ave S.W.) on June 4, 2019, from 6 – 8 p.m.

In total, the project team talked to 70 people and over 60 businesses through the open house events and door knocking sessions. There were 585 unique visitors and 190 unique contributions to the online engagement page.

We are now completing some additional technical work on the design for Phase 3 to address concerns in the community regarding availability of on-street parking. We look forward to sharing the completed designs with the community later this year.

Cycle track network

Why was 12 Avenue South chosen as a cycle track corridor?

A number of corridors, or groupings of streets, were identified for the Centre City study area based on the idea that a single cycle track within the corridor would be able to appropriately serve the demand for that specific area. For each corridor, a number of potential cycle track alignments were identified.

These alignments were based on current best practices in North American bicycle planning and design, understanding of the local context, and feedback received during the ongoing engagement. These cycle track alignments (combining a street selection and facility layout) were then evaluated based on a set of technical criteria including connections to key destinations, existing and future bicycle demand, impact on other modes, conflicts at driveways and transit stops, and cost and constructability. Based on this analysis, 12 Avenue was selected to serve the demand for an east/west corridor in the north part of the Beltline. Additional background information can be found in the Centre City Cycle Track Network- Development and recommendations report.

How did you choose this type of cycle track design?

To align with Phase one construction timelines, pinned curb and flexible posts were used for the cycle track extension. Additionally, the cycle track includes many design features that improve safety at intersections and where people cycling and people driving are mixing. Intersections have bicycle signals and some intersections have a separated signal phase for people turning. “Yield To Bikes” signs were installed at intersections and driveways to remind drivers they must yield to before turning left across the cycle track. Driveways and intersections with high volumes of people cycling and driving have dashed green paint.

Future extensions

What about a cycle track extension on the east end (Olympic Way S.E. to the Elbow River)?

We have started planning and designing the east extension, from Olympic Way S.E. to the Elbow River pathway, and are working with CMLC and stakeholders to determine opportunities. More information will be available in the fall.
