Road closure at the roundabout on Iowa 150 west of Urbana in Benton County begins on Monday, April 17

NEW HAMPTON, Iowa – March 31, 2023 – If you travel on Iowa 150 near Urbana you should be aware of an upcoming road closure. Beginning on Monday, April 17 until mid-May, weather permitting, crews will close the roundabout on Iowa 150 west of Urbana at the intersection with 31st Avenue and 55th Street in Benton County so crews can resume construction of concrete shoulders and work on erosion control.

During this road closure, motorists will follow a marked detour route using Interstate 380, and Benton County roads D-48 and V-71.

Help keep everyone on the road safer. Drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, you should stay alert, allow ample space between vehicles, and wear seat belts.
