The northern section of U.S. Route 209 was closed on Friday afternoon due to the failure of a section of the road. The highway is a major north-south artery that runs through the park’s Pennsylvania District and is under NPS jurisdiction. The failure involved a 150-yard segment of the road about two miles north of Route 739. The embankment on the east side of the road has slumped, the pavement has begun to separate, large cracks have appeared in the surface, large voids have developed under the pavement, and the road has dropped by approximately six inches in some places. Federal Highways Administration engineers were on site Friday and determined that the road was unsafe for motor vehicles. It is likely that the damage was caused by this year’s record rainfall, coupled with the impacts of Hurricane Irene and Tropical Storm Lee. A timeframe for completion of emergency repairs is unknown at this time.
