The Kansas Department of Transportation (KDOT) plans to close about four miles of U.S. 169 in Anderson County Wednesday between Welda and the U.S. 169/U.S. 59 junction.
Motorists will be diverted east to Moran, then north on U.S. 59. Signage will indicate the detour.
The closure will be in effect until late 2020.
The highway closure is part of the $21 million project to reconstruct and rehabilitate 7½ miles of U.S. 169 in Anderson County. Work started in early March.
Bettis Asphalt & Construction of Topeka is the primary contractor.
