On August 12, 2019, the National Capital Commission (NCC) will begin the rehabilitation of the Hog’s Back swing bridge to provide a reliable and durable bridge. As many of the bridge components have reached the end of their life cycle, the bridge will be rehabilitated to extend the remaining service life by 20 to 30 years. Work is expected to be completed in May 2020.

A detour will be established along Riverside Drive, Heron Road Bridge and Prince of Wales Drive for motor vehicle traffic. Modifications have also been made to the Heron Road and Prince of Wales Drive intersection to accommodate additional traffic volume.

Pedestrian and cyclist access will be maintained during the construction period. These works will not cause any closures on Colonel By Drive. Canal navigation will not be interrupted by these works.

Regular construction noise and equipment are to be expected at the site when the bridge is being rehabilitated. Work will be undertaken Monday to Friday, between 7 am and 8 pm. There may also be occasional work on Saturdays and Sundays.

The NCC urges motorists, cyclists and pedestrians to exercise caution, respect working crews and equipment, and obey signage and flag persons at the site.
