The state plans to close single lanes on Interstate 65 between mile markers 33.5 and 43.5 this week.

It’s part of the $54.7 million project to rehabilitate 21 miles of pavement and improve 20 bridges between State Road 56 in Scott County and U.S. 50 in Jackson County.

The restrictions began at 7 p.m. Sunday and will end at 1 p.m. Friday, according to a news release from the Indiana Department of Transportation.

Crews from John R. Jurgensen Co., the state’s contractor, will make concrete pavement repairs, clean out underdrains, continue ditch work, install guardrails and place stone on shoulders.

Today, the left lanes of the interstate both northbound and southbound will be closed between mile markers 33.5 and 38.5 near Austin.

From Tuesday to Friday, the right lanes both northbound and southbound will be closed between mile markers 38.5 and 43.5.
