– Parks Canada has been preparing drawings and plans for the Glen Ross Swing Bridge and Lock 7 rehabilitation project. The project will be tendered in July 2017, with a target to begin the work in September 2017.

This project will include repairs to the swing bridge, lock chamber walls, sluice tunnels and upgrades to the water level control valves. The swing bridge will undergo both structural and mechanical repairs and will be upgraded to a highway load rating. The bridge will be removed from its position and transported to a shop for steel repairs and repainting, extending its life by approximately 50 years.

In order to complete these repairs, Glen Ross Road will be closed to vehicular traffic at the Glen Ross Lock 7 Swing Bridge from September 2017 to spring 2018. A pedestrian bridge will be installed to ensure foot traffic across the waterway is maintained throughout the duration of the bridge closure. Additionally, a small parking lot will be provided on the north side of the bridge for those that need to travel north of the bridge frequently. This provides the option of leaving your car north of the bridge and walking to the parking lot or being dropped to the lot instead of driving the detour. Alternately, a detour map is provided below.

Detour Map

The detour map displays a closure at the Glen Ross Lock 7 bridge. Local traffic may use the Frankford Road crossing as a temporary detour until the construction is completed.

Specific details about the timing of the road closure are not known at this time. Parks Canada will share more precise updates after the tender period closes and the contract is awarded, as well as closer to the start of construction. Navigation will not be affected by the bridge repairs.

Parks Canada would like to thank the community for their cooperation and understanding as we complete this important infrastructure work. These historic investments will mitigate health and safety risks, halt the loss of nationally significant built heritage and stimulate the economy in communities across the country.
