Concrete Rehabilitation, Locks 42 & 43
The concrete lock and approach walls at Couchiching Lock 42 and Swift Rapids Lock 43 will be refaced over the next few years. We anticipate that this work will begin in the non-navigation season of 2017. Residents may notice more trucking activity as debris is hauled away and concrete is poured over the winter months. The noise of generators may be heard over the winter months as work spaces under a temporary enclosure are heated to allow the curing of the concrete.
The Hamlet Bridge is a combination fixed and swing bridge. The bridges will be replaced will a similar look to respect the historic landscape of the area. The bridges will be raised to reduce immersion of mechanical components during high water events, as well as correct runoff away from the bridge. The road abutments, east pier and bridge operator’s building will be fully replaced, and mechanical and electrical systems will be upgraded.
