MoreThe fixed bridge at Couchiching Lock 42 was constructed in 1931, and carried Canal Road over the Trent-Severn Waterway directly downstream of the lock. The new bridge – primarily built offsite, and then assembled onsite to mitigate impact to the public - will have a lifespan of approximately 50 years. The load restrictions of the bridge will not change.
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.
