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.
