This project is scheduled to start in spring of 2025 and be completed by fall of 2026. Construction will be phased in 2 stages.

Construction is tentatively scheduled to begin in spring of 2025. During this phase, the south side of the bridge structure will be replaced. Sidewalk and road reconstruction, and other associated works will take place on the south side of the project site.

Initiation of Stage 2A is tentatively scheduled to begin in spring of 2026. This phase will include the replacement of the north side of the bridge structure. Road and sidewalk reconstruction and other associated works will also be completed on the north side of the project site.

Initiation of Stage 2B is tentatively scheduled to begin in fall of 2026. During this stage, a multi-use path will be constructed on the south side of the bridge.

The City of Hamilton will replace the Grindstone Creek Bridge on Dundas Street East (Highway 5) between Mill Street and Reynold Street in Waterdown. This replacement is required due to the age and condition of the bridge.

The project will replace the bridge structure, reconstruct Dundas Street East within the project area, upgrade and relocate utilities, and improve active transportation.

There are several planned improvements within the project area.

Vehicular, pedestrian and cycling traffic will be impacted for the duration of construction due to LANE CLOSURES. The project will be completed in two phases and impacts to traffic will differ from phase to phase. For more information refer to  Timelines  Section.

One lane, in the eastbound direction (going towards Burlington) will be open to vehicular traffic, and the sidewalk on the north side of the bridge will be open.  Pedestrians will have access to a pedestrian crossing allowing them to safely cross from the south side of the street to the north side. 

Two lanes will be open on the south side of the bridge facilitating both eastbound and westbound vehicular traffic. Pedestrians will have sidewalk access on the south side of the bridge and will have access to a pedestrian crossing allowing them to safely cross from the north side of the street to the south side.

The south shoulder lane will be closed over the bridge. Two lanes will remain open facilitating both eastbound and westbound vehicular traffic.  Pedestrians will have sidewalk access on the north side of the bridge and have access to a pedestrian crossing allowing them to safely cross from the south side of the street to the north side. 

During Stage 1 of construction, one eastbound lane will remain open only. The westbound traffic will be detoured down Avonsyde Boulevard, Parkside Drive, and Hamilton Street North, as shown in the map below. This detour route will be available for the duration of construction and can be used by drivers to avoid traffic congestion over the bridge replacement site.
