The Indiana Department of Transportation plans to close State Road 135 near Freetown on Monday so an existing drainage structure at a branch of Salt Creek’s south fork can be replaced as part of a $456,650 two-bridge contract.

INDOT officials anticipate installation of the new 10-foot-by-5-foot concrete box culvert, located 5.2 miles north of U.S. 50 in Jackson County, will require about three weeks to complete.

Olco of Batesville, the state’s contractor, also will build a 142-inch arch culvert on State Road 135 at a branch of Hamilton Creek, located 7.6 miles north of State Road 58 east of Christianburg Road in Brown County. That structure will be constructed once the highway reopens in Jackson County. It will require a 30-day closure.

A Jackson County bridge on State Road 58 at Bee Creek, located 3 miles west of State Road 135, also is being replaced.
