INDOT plans upgrades for U.S. 421 and Ind. 32 roundabout


By Mark Ambrogi

The roundabout at the intersection of U.S. 421 and Ind. 32 will receive repairs for the second time since opening in September 2015.

However, this time the roundabout will not be closed for traffic. It will be repaired under traffic, likely with flagging, said Debbie Calder, Indiana Dept. of Transportation’s communications director for the Crawfordsville district.

Calder said INDOT officials reviewed the roundabout and have recommended that the following changes be made:

  • The east splitter island will be tapered down and updated with reflective paint.
  • A “Keep Right” sign will be installed at the end of the splitter island on the east leg of the intersection.
  • Pavement markings in the westbound lane on the east leg will be repainted to better guide traffic into the intersection.
  • Worn pavement markings will be repainted.
  • Raised pavement markers left in place along the east leg will be removed, and holes will be filled with epoxy.

Calder said INDOT does not see the intersection as dangerous but that the changes will improve traffic flow.

“It was brought to our attention by a concerned citizen,” Calder said.

Calder said the contractor that built the project is still under contract and is going to make the changes before the end of the year. She said the project engineer didn’t have a timetable yet about how long the repairs will take.

The intersection closed for construction of the roundabout from July 6 to Sept. 21, 2015. Then, it was closed for nine days from Nov 2 to 11 in 2015 for repairs to the mountable curb on the center island.
