The city of South Haven, Michigan is notifying drivers that they should expect closures and detours near Dunkley and Dyckman Avenues starting this week as a water main construction project gets underway. The project will happen in phases through early May, with road closures, lane restrictions, and detours in place.

Why it matters

This construction project is part of a larger $42 million effort by the South Haven Department of Public Works to upgrade the city's aging water and sewer infrastructure. The closures and detours will impact traffic flow in the area, requiring drivers and pedestrians to plan ahead and follow posted signs.

The details

During the first phase, Dunkley Avenue will be closed to through traffic north of Dyckman for several weeks, with detours posted along Phoenix Street, Blue Star Highway, and Wells Street. Bridge traffic will remain open. In the second phase, westbound Dyckman and part of Dunkley will be restricted, with additional detours in place and some bike lane closures. Pedestrians are urged to follow posted signs and avoid construction zones. Final work will include paving and concrete repairs, with brief closures announced ahead of time.

• The project will happen in phases through early May 2026.
• The first phase with the Dunkley Avenue closure will last for several weeks.
