4th Street Improvement Project

Proposed Improvements

The City of Willmar is planning to improve 4^th Street SW in 2026. Design is currently underway, with construction anticipated to begin in May. Improvements include:

• Street diet
  • The proposed street diet involves reducing the existing roadway width from approximately 52 feet to a consistent width of 38 feet. This modification will continue to accommodate on-street parking on both sides and providing cost savings for the city and adjacent property owners—both in terms of initial project expenses and long-term maintenance.
• Asphalt streets with concrete curb and gutter
• Sidewalks improvements
• Concrete driveway aprons
• Sanitary sewer system
• Water main, hydrants and water services
• Storm sewer system
