The construction of a roundabout on Iowa 150 near the 31st Avenue and 55th Street intersection is expected to begin May 31, weather permitting, according to the Iowa Department of Transportation’s New Hampton construction office. 


During construction, access from Iowa 150 to 31st Avenue and 55th Street will be closed. A marked detour will be in place using Interstate 380 and Iowa 150. This access is scheduled to be closed until early October. A portion of Iowa 150 included in the detour route is currently being resurfaced and lane closures might impact travel times. The resurfacing project is expected to be completed in late June.
