Phase 2 of the Worthington and Big Walnut Road intersection will begin on September 5. The south and west legs of the intersection will close while the north and east legs reopen to traffic. Local traffic should enter/exit the work zone from the west and south ends of the project beginning Tuesday. Overall completion is planned for mid-November.

Road construction is scheduled to begin May 30, 2017 on a project to upgrade the intersection of Worthington and Big Walnut Road with turn lanes and a new traffic signal.

The first construction phase will include a closure of Big Walnut Road from Worthington Road to Satinwood Drive/Ketterington Lane, and Worthington Road north of Big Walnut Road. Traffic will be matinained on the west and south legs of the intersection.

Phase 2 will begin in September 2017 with a reversal of the detour. Worthington Road south of Big Walnut, and Big Walnut East of Worthington Road will be closed. Traffic will be maintained on the north and east legs of the intersection.
