The twin bridges on I-79 above North Boundary Road are about to be replaced. A temporary bridge will be set up to handle traffic from the affected spans, which will be replaced in sequence over the summer. To place the temporary bridge, North Boundary Road between Rt. 19 and Marshall Road will be closed the weekend of June 1, weather permitting. During the two-day closure, a detour to the eastern portion of North Boundary Road, including Community Waterpark, will be via Marshall Road and Rowan Road.
