Do you feel your local government provides adequate notice and detour options for road construction projects?

Kansas City officials have closed 40th Street between Southwest Trafficway and Pennsylvania Avenue to facilitate necessary resurfacing work. This project adds to existing construction closures currently in place on nearby Mill Street and Westport Road.

Why it matters

The resurfacing project is part of ongoing efforts to maintain local infrastructure and improve street surfaces for commuters. These closures require drivers and pedestrians to navigate detours while crews conduct mill and overlay work.

On-street parking is prohibited on 40th Street from 6 a.m. to 6 p.m. during active construction. Crews expect the 40th Street resurfacing project to conclude by the end of the current week.

The players

City of Kansas City

The local government authority manages municipal infrastructure, including street maintenance and traffic regulation across the city.

The details

Crews are performing mill and overlay work to rehabilitate the road surface on 40th Street. To ensure safety, pedestrians are being diverted to sidewalks on the opposite sides of the closed streets, including paths along Mill Street and Westport Road.

September 29, 2026: The city began resurfacing work on 40th Street.
6 a.m. to 6 p.m.: Parking is restricted on 40th Street during construction hours.
End of the week: Completion is expected for the 40th Street work.
End of 2026: Mill Street and Westport Road are scheduled to reopen.

Market Landscape

This project aligns with the City of Kansas City's annual street resurfacing maintenance plan intended to preserve public transit assets. These localized closures reflect a broader industry trend of grouping infrastructure updates to maximize logistical efficiency.

Commuters should expect travel delays in the Westport area and must avoid parking on 40th Street during daylight hours. Pedestrians must follow posted signage to navigate construction zones via detours on opposite sidewalks.

The takeaway

Residents should plan for longer transit times in the Westport neighborhood while these road improvements are underway. Checking local signage daily remains the best way to avoid parking citations or unexpected route changes.
