12 Avenue South Improvements


Project update

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

  • Extending the dedicated lane for people cycling from 11 Street to 15 Street S.W.
  • Bicycle turn boxes at 12 Avenue and 11 Street.
  • Improved travel time for drivers by providing three uninterrupted driving lanes for morning rush-hour.
  • The rush hour parking restriction was removed on the north side of 12 Avenue between 15 Street S.W. and 16 Street S.W.
  • A loading stall was provided on the east side of 12 Street S.E. just north of 12 Avenue South.

The Phase 3 design and What We Heard engagement feedback was presented in a public information session at the Sunalta Community Hall on Dec. 11. Overall improvements as part of Phase 3 construction include:

  • Extending the two-way cycle track facility on the north side of 12th Ave. S.W. from 15th St. S.W. to 19th St. S.W., and then on the east side of 19th St. S.W. from 12th Ave. S.W. to 10th Ave. 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 two consistent eastbound vehicle lanes on 12th Ave. S.W. from 15th St .S.W. to 18th St. S.W. and one vehicle lane from 18th St. to 19th St. S.W., with parking consolidated to the south side of 12th Ave. S.W. Additionally, one southbound vehicle lane is retained on 19th St. S.W. from 10th Ave. S.W. to 12th Ave. S.W., with parking consolidated to the west side of 19th St. S.W.
  • Improving sidewalk ramps at most intersections to line up with pathway routes crossing the street.

Construction of Phase 3 is anticipated to begin in Summer 2020.

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 could still be made.

Work on 12 Avenue South will be done in three phases:

Phase Scope Timeline
Phase one: road improvements Upgrade driving lanes along 12 Avenue South between 11 Street S.W. and 4 Street S.W. Complete
Phase two: western extension Extend the cycle track west on 12 Avenue South from 11 Street S.W. to 15 Street S.W. Complete
Phase three: connection to the Bow River Pathway Extend the cycle track on 12 Avenue South from 15 Street S.W. to 19 Street. S.W. then across 10 Avenue S.W. to the Bow River Pathway. Summer 2020

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

On-street parking will be consolidated to the south side of the roadway to allow for smooth and predictable traffic flow.

Before construction begins, residents living on 12 Avenue SW can apply for a residential parking permit. This process requires 80% of residents on each block to sign a petition supporting the installation of a parking restriction. On 12 Avenue SW, the petition would need to be circulated to residents on both the north and south side for each block.

During construction, parking on the north side of 12 Avenue SW would be removed, parking on the south side of 12 Avenue SW would be maintained.

Residents may choose to wait until construction is complete to apply for a residential parking permit – in this case, the petition would require 80% of residents only on the south side on each block to action a residential parking zone. If successful, residents on both sides of the street would receive a parking permit.

Cycle track network

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.

To align with Phase one construction timelines, pinned curb and flexible posts will be 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 will have bicycle signals and some intersections will have a separated signal phase for people turning. “Yield To Bikes” signs will be 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 will have dashed green paint.

The City is interested in advancing the 12 Avenue cycle track extension east from Olympic Way S.E. to the Elbow River pathway. We have started planning and designing the east extension and are working with CMLC and stakeholders to determine what’s feasible for 2019.
