DAYTON — Construction work on highways U.S. 169 and Iowa 175 between Dayton and Harcourt will begin Wednesday.

According to the Iowa Department of Transportation’s (DOT) Jefferson Resident Construction Engineer office, two sections of roadway will be closed by crews during the resurfacing projects.

Approximately 1,200 feet west of the east junction of U.S. Highway 169 and Iowa Highway 175 between Dayton and Harcourt will close on Wednesday. A three-mile section will be resurfaced to Linden Street on the west edge of Harcourt. The area through Harcourt will be gapped, and construction will resume on U.S. Highway 169 at the west junction of U.S. 169 and Iowa 175.

Construction will then proceed north on U.S. Highway 169 for 11.7 miles to approximately a half mile south of U.S. Highway 20.

During construction, the roadway will be closed. Traffic will be allowed to cross the construction area at most intersections daily, but there will be times that crossing is restricted due to the paving operation.

According to the DOT, when each roadway is closed, detour routes will be in place. The Iowa 175/U.S. 169 closure east of Harcourt will follow a marked detour route using U.S. 169, County Road E26, and Iowa Highway 144. The U.S. 169 closure north of Harcourt will follow a marked detour route using U.S. 20, County Road P29, Iowa 175 west of Harcourt, Iowa 144, and U.S. 30.
