Reconstruction work on U.S. Highway 75 between Plymouth County Road C-80 near Sioux City, and Plymouth County Road C-60 near Hinton will begin next month.
Traffic will be shifted into a head-to-head pattern in the southbound lanes to accommodate reconstruction of the northbound lanes.
The Iowa DOT says project work will begin at 8 a.m. Monday, April 1st, and run through the summer until Thursday, October 3rd.
Left turns will be prohibited through the work zone during the construction.
Peterson Contractors, Inc. was awarded the $8.8 million contract for this project.
