Indiana Department of Transportation’s contractor for the $1.9 million roundabout project at the west end of U.S. Highway 50’s North Vernon bypass will have construction crews onsite beginning Wednesday morning. INDOT says that motorists will be shifted to the north side of U.S. 50. Walnut Street and County Road 400 West will close.

Milestone, the state’s contractor, plans to build the east half of the intersection project during Phase I.

• Phase II construction builds the west half. Traffic shifts to the center of the roadway. Walnut Street and C.R. 400W will remain closed.
• Phase III construction builds splitter islands and the center island. Traffic will be normalized. Walnut Street and C.R. 400W remain closed.
• Phase IV construction builds the western curb entrance to the roundabout. Walnut Street and C.R. 400W open to traffic.

INDOT’s project replaces the existing stop-control configuration at U.S. 50/Walnut Street-C.R. 400W—located two miles west of North Vernon—with a single-lane roundabout measuring 166 feet in diameter with a 16-foot-wide lane and 14-foot-wide truck apron.
