Drivers heading east on Highway 30 may find additional road construction delays as the Greene County Board of Supervisors approved a motion that will add six temporary stop signs along the detour route at Grand Junction. The signs will be at intersections along V Ave. on the detour, for north and southbound traffic at 185th and 240th Streets, for southbound traffic at 210th Street and for northbound traffic at 230th Street. The signs will be in place until the Highway 30 road construction project is completed in November.
