SIOUX CITY, Iowa (AP) — Woodbury County in western Iowa has approved repair plans for part of a two-lane highway that will eventually be widened. The county board agreed Tuesday to grade part of U.S. Highway 20 in 2016. The paving process will close the road west of Correctionville, and is part of a bigger plan to widen a 12-mile section of the two-lane roadway.

The Sioux City Journal reports the plans will require a detour onto eight miles of County Road D22, also known as Old Highway 20. That county road will be widened and repaired in 2015 in preparation for the extra traffic. The state Department of Transportation says the current widening project, between two miles east of Moville through Correctionville, is scheduled to be completed in 2017.
