Spring 2021 marks the start of a multi-year construction project known as the South Bow River Bridge project. The Government of Alberta is replacing the eastbound bridge and widening the westbound bridge in anticipation of increased traffic on the Calgary Ring Road. This project also includes a stand-alone pedestrian crossing that will provide a better and safer connection to the existing pathway system. Additional roadwork plans include widening and improvements to Stoney Trail between Macleod Trail and McKenzie Lake Blvd/Cranston Blvd, and modifications to the ramps at Sun Valley Blvd/Chaparral Blvd and Stoney Trail SE.
Over the next week, roadside preparations will begin in anticipation of the eastbound bridge demolition. This construction milestone will impact the following:
- Vehicles: Eastbound lane detour; traffic will be redirected into westbound lanes. *Please find vehicle detour map attached.
- Pedestrian Access Across the Bridge (east/west): Permanently closed until the new pedestrian bridge is open. Access across the river will be via the South Fish Creek bridge.
- Pedestrian Access Under the Bridge (north/south): Temporarily closed for ~6 weeks. Pedestrians to use McKenzie Lake Blvd or Chaparral/Sun Valley Blvd crossings.
Additional pedestrian pathway closures can be expected intermittently throughout the course of construction, and will be communicated as they arise. *Please find attached a pedestrian detour map with further details.
Further information on project details and closures/detours can be found on the alberta.ca/southbowbridge project page. This page will be updated with relevant information throughout the course of construction. On this page, there is also an opportunity to subscribe to email updates.
To ensure the safety of site workers and the travelling public, project boundaries are clearly identified with netting and/or line, on-site signage, and the use of flaggers. Please respect all site signage and stay out of marked construction areas. We thank the public for their cooperation finding alternate routes during construction. We encourage the public to plan ahead, and reference the following resources before travelling:
We are aware of the impacts this project has on nearby communities, and the contractor is working to limit the amount and frequency of closures to the pathway system. This project is part of the Calgary Ring Road, and once completed will be part of over 100 kms of free-flow travel around the city, and improve access to amenities within Calgary.
