Dubuque County, Iowa — Motorists traveling in rural Dubuque County should prepare for a full road closure on Ungs Road beginning Tuesday, March 31, 2026, at 8:30 a.m., as county crews undertake a culvert replacement project.

The work will affect a 1.01-mile section of Ungs Road from Clear Creek Road to Lake Road. The road will be completely closed at the site of the culvert repair, located just north of 21958 Ungs Road (near Guttenberg in the area of Clear Creek and Lake Road intersections).

This short-term project involves removing and replacing the existing culvert to maintain the integrity of the roadway and drainage system. The estimated duration is approximately one day, though completion depends on weather conditions. Crews will work to reopen the road as quickly and safely as possible. 

Details of the Closure

•  Road: Ungs Road

•  Section Affected: From Clear Creek Road to Lake Road (1.01 miles)

•  Issue Type: Construction – Culvert Replacement

•  Start Time: Tuesday, March 31, 2026, 8:30 a.m.

•  Closure Type: Full road closure for the length of the work zone

•  Location Specifics: Closure centered just north of the property at 21958 Ungs Road

•  Expected Duration: 1 day (weather permitting)

Local residents and property owners in the immediate area, including those near the dairy or agricultural operations along Ungs Road, have been or will be directly notified. The closure is consistent with similar culvert replacement projects the county has completed in recent years on roads such as Thielen, Curoe, Higginsport, Humke, and others, where full closures allow for efficient, safe work with minimal long-term disruption. 

Detours and Alternate Routes

Official detour information has not been specified in the initial notification, but drivers should expect to use nearby county roads such as Lake Road, Clear Creek Road extensions, or connections via Thunder Road, Heim Road, or Route 52 (depending on direction of travel).

Travelers are strongly advised to:

•  Check the Dubuque County Engineer’s office website or road closure map for real-time updates and posted detour signs.

•  Use GPS navigation apps with current road closure data enabled, as rural routes can change quickly.

•  Allow extra travel time if Ungs Road is part of your regular commute or access route to properties in the area.
