Bridge expansion joint replacement projects

The City's annual bridge inspection program has identified the deterioration of expansion joints at seven bridge locations across the city. The timely replacement of these joints must be carried out to maintain a safe traffic service and prevent future unplanned road closures.

Project update - November 2023

During construction, there may be delays due to reduced lanes. The City will make every effort to limit impact on traffic, however motorists are advised to expect some delays. Regular updates will be posted on this page as we move into construction. Please watch out for crews and detour signage.

Construction work and impacts

17th Ave SE over WID Canal - April 10 - October 2023

Work for the 17 Avenue S.E. over WID Canal Bridge started in mid-April. The north and south bridge barriers required repair along with the removal and replacement of new concrete.

Pedestrian and cyclist access on the north side of the bridge was redirected to a temporary pathway outside of the work area. Users are advised to follow site signage and exercise caution around active work areas.

The full project was completed October 16, 2023.

64 Ave NE over CP Rail (west of Deerfoot Trail) - May 8 - September 2023

Work for the 64 Avenue N.E. over CPR Bridge started in early May and has now been completed. Crews may be in the area to paint road lines, but the rehabilitation work has been completed.

Work is being completed on the Deerfoot Trail exit northbound at 64 Avenue. The Deerfoot Trail improvements are coordinated by Alberta Transportation – to receive updates, please go to the Alberta project webpage.
