The Indiana Department of Transportation plans to replace a box culvert channeling Singer Ditch under State Road 235 east of Medora next spring.

Milestone Contractors has been contracted to remove the existing structure and replace it with 16-by-6-foot reinforced concrete box sections measuring 65 feet in width.

Operations expected to begin after April 1 will require a 30-day closure of State Road 235.

A state detour will route traffic around the legal drain culvert site in Driftwood Township — located 1.65 miles west of State Road 135 — via State Road 135 and U.S. 50.

The Columbus contractor plans to clear and stake the site in November. Utilities will begin relocation operations after Jan. 1.

The value of the contract is $316,400.
