Crews are working on the new Salem Circle Bridge on US 41 at Nortonville in southern Hopkins County.
It has been closed since December 2017 when cracks appeared in the support structure.
A CSX project and water main break eroded the embankment on an overpass.
Governor Matt Bevin approved $500,000 for repairs.
The bridge connects more than 100 homes, businesses, and a church.
Closing it forced residents to take an extended detour.
Drivers should watch for stopped traffic in the area.
Work is expected to take two to three weeks.
