Location

The Caledonia Bridge, also known as the Grand River Bridge (built 1927) is a road bridge located in Caledonia, Ontario, Canada on Argyle Street. The bridge is the only nine-span bridge of its kind in Canada and is considered the first reinforced concrete bridge of its type ever built.

The bridge is on the Ontario Heritage Bridge List and is designated by the Haldimand County LACAC (Local Architectural Conservation Advisory Committee).

The bridge is scheduled to be replaced by a new bridge due to structural damage and age. A number of bridge deficiencies were found requiring action. The condition included structural deficiencies, structural deterioration, insufficient roadside safety, foundation problems and inadequate hydraulics. The engineering consulting firm Morrison Hershfield was approached to conduct a Context Sensitive Design Workshop for the bridge. They involved stakeholders and representatives from the public to participate in the bridge design to address various environmental aspects of the project. Completion of the bridge was tentatively scheduled for 2012, but as of 2024, minimal work has been done towards its replacement.
