A section of Indiana 1 is scheduled to close for 40 days in Wells County.
The state highway will close between County Road 300 South and just south of Indiana 116, beginning Monday, weather permitting, the Indiana Department of Transportation announced Wednesday.
Small structures will be replaced over Crosbie and Delong ditches, INDOT said.
The official detour uses Indiana 218, Indiana 116 and Indiana 1.
The road is expected to reopen by the middle of August, the announcement said.
