90 Avenue S.W. and Southland Drive connections


Project update - October 10, 2019

The new 90 Avenue S.W. underpass and the pathways in the area are now open. Residents can use both underpasses as they enjoy the pathways between South Glenmore Park and Fish Creek Park. Overall, construction is coming to an end for the Southland Drive and 90 Avenue S.W. extensions. Crews are cleaning and preparing the site for the winter and until the SW Ring Road opens in fall 2021.

Check out the video project update, highlighting the improvements for the two extensions:

About the project

The 90 Avenue S.W. and Southland Drive connections project is one of several City-led projects to connect Calgary's road network to the ring road and will accommodate changes to traffic volume and patterns that are expected after the opening of the Southwest Ring Road​ (SWRR).

The City is constructing the extension and connection of both 90 Avenue S.W. and Southland Drive within the city limits to the Southwest Ring Road (SWRR). These connections will improve the local road network by distributing traffic more evenly in the area and will provide easy access to the SWRR for people travelling north and south - another travel option instead of using 14 Street S.W.

It features a number of benefits:​

  • Creating pathway connections under 90 Avenue S.W. and Southland Drive. These well lit underpasses will create a safe and uninterrupted pathway between communities, the current off-leash dog park, as well as South Glenmore and Fish Creek parks.
  • Widening Southland Drive from two to four lanes between Oakmoor Way and Oakfield Drive S.W. to match the rest of the roadway.
  • Installing noise barriers along Southland Drive​ between Oakfield Drive and Oakmoor Way.
  • Installing traffic signals and a pedestrian crossing at the Southland Drive and Oakfield Drive S.W. intersection.
  • Access to the Oakridge off-leash area and pathway system will remain in place with temporary adjustments to accommodate construction.

After the SWRR opens and traffic settles into its new pattern, the City will be monitoring several intersections along 90 Avenue S.W., in case further modifications to the road or intersections are necessary.


As part of this project, we will be planting new trees more than double the amount removed by the time construction is complete. New trees are planted in the closest suitable location to replace the impacted trees. The project team plans to use a variety of species suited for the area that will provide shade along the pathways.

Calgary's southwest ring road

The City is responsible for the design and construction of the projects connecting Calgary's road network to the ring road because they are located within city limits.

West Calgary ring road

The West Calgary Ring Road (WCRR), between Highway 8 and the Trans-Canada Highway, contains the final nine kilometres of the Calgary Ring Road. Most of the road will be built on the existing Transportation Utility Corridor owned by the Government of Alberta.

The WCRR project will be completed in three parts – the north project, south project, and twinning of the bridge over the Bow River. For more information on this project, visit the West Calgary Ring Road home page.
