Roundabout project beginning on U.S. 50

The first phase of a $1.9 million roundabout project at the west end of the U.S. 50 bypass at North Vernon will begin this week, starting with signage being put in place Monday. Construction operations will follow.

Phase I calls for building the east half of the roundabout. Traffic will shift to the westbound side of U.S. 50. Walnut Street and County Road 400W will close, according to a news release.

Columbus-based Milestone, the Indiana Department of Transportation’s contractor for the project, will replace the existing stop-control configuration at U.S. 50 and Walnut Street/County Road 400W — located two miles west of North Vernon — with a single-lane roundabout measuring 166 feet in diameter. Plans call for splitter islands to be installed on rebuilt road approaches. The roundabout’s 16-foot-wide lane will encircle a center hub designed to accommodate semi-trailers on a 14-foot truck apron. Lighting is included in the project, INDOT said.
