Update from October 25, 2018

Washington County opened Harpers Ferry / Sandy Hook Road at 4:00 p.m. on October 25. The debris removal is complete at the landslide location, but permanent stabilization still needs to be put in place. People traveling on the road adjacent to the landslide area should exercise caution. The public will be notified prior to continued stabilization work at the site.

Update from October 16, 2018

Debris removal is almost complete at the landslide location. The next stage of the work involves permanent stabilization of the mountainside. Before the stabilization begins, a final design must be approved by the State Historic Preservation Office of Maryland. Once the design is approved, the contractor will be able to give an estimated timeline for how long the work will take. After all work is complete, the road can reopen.

Update from June 12, 2018

The National Park Service is continuing to monitor dynamic conditions of a landslide near Maryland Heights along Harpers Ferry Road/Sandy Hook Road while actively working with a variety of experts to determine the best way to stabilize the slope so Washington County Public Works can safely reopen the road.

A 100 foot by 100 foot section of the hillside below Maryland Heights slid following two days of unusually heavy rainfall. From May 15-17 over 15 inches of rain fell in southern Washington County, Maryland; that's more than double the typical total rainfall for all of May! Since then, the region has continued to experience uncharacteristically high amounts of precipitation causing flooding in the area and further instability of the slope.

Continuously changing conditions have made it difficult for stabilization work to begin, but the National Park Service will be working to remove loose materials as well as repair the downed utilities in order to reduce the hazards in the area from just north of Hoffmaster Road to Clark Road. However, slope stabilization is needed before crews can safely access the area to perform work.

The popular Maryland Heights hiking trail remains open as it does not cross Sandy Hook Road in the area of the landslide. National park rangers continue to monitor the situation and the trail may close if safety becomes a concern.

While we do not know when conditions will allow the road to safely reopen, we are committed to working as quickly as possible to reopen this vital transportation link.
