Construction work is underway on one of the largest infrastructure projects in the history of the City of Windsor.

Valued at more than $110 million, the project calls for extensive improvements to the Banwell Road and E.C. Row Expressway interchange and corridor.

The project includes two components.

The first involves the construction of a new Banwell Road overpass and interchange at E.C. Row Expressway, watermain, storm sewer system, pavement, lighting and multi-use trail system. This work began the week of September 15, 2025.

The Government of Ontario is contributing $50 million towards the construction of the interchange.

The second includes widening Banwell Road from a two-lane rural road to a six-lane urban cross-section, starting near Mulberry Drive and continuing over the E.C. Row Expressway to Intersection Road. At that point, it will taper to four lanes, cross the CPKC railway, and merge with the widened section currently under construction by the County of Essex.

The work also includes a new intersection for access to the NextStar Energy EV Battery Manufacturing Plant site as well as the future Tecumseh Hamlet secondary planning area, watermain, storm sewer systems, stormwater management, multi-use trail, pavement and lighting.

The full Banwell corridor currently accommodates approximately 10,000 to 17,000 vehicles daily. Once the NextStar plant is fully operational, the Tecumseh Hamlet development is complete, and future development in the surrounding area occurs, the city projects traffic volumes will double north of the interchange and triple south of it.

Detailed design of the project was finalized in late 2024 and utility relocations, species-at-risk surveys and land acquisitions are now complete.

The overall Banwell Road corridor project also includes two other projects that are receiving funding from the Housing-Enabling Core Servicing Stream under the province’s Municipal Housing Infrastructure Program.

The work includes the extension of Wyandotte Street East from Banwell Road East to Jarvis Avenue, which is currently in the detailed design phase; and intersection improvements at the existing Banwell Road/McHugh Street intersection.

The City of Windsor expects the projects will help unlock more than 3,000 housing opportunities.

“We are Building Windsor’s Future with a focus on investment, growth and sustainability. The Banwell projects are a major piece of the puzzle, said Mayor Drew Dilkens. “Work on this vital arterial road will further improve access to Canada’s first electric vehicle battery plant, while also supporting supply chain businesses across Windsor as well as the new Fancsy Family Hospital.”

The current schedule for the overall project forecasts substantial completion in 2027 with some surface asphalt and final restoration works in 2028.
