The National Park Service (NPS) will begin construction on the Level 33 dry-laid stone wall just across the Potomac River from Harpers Ferry, WV this March. The wall shows significant signs of instability and stone loss, causing distress and unsafe conditions on the supported public roadway. Repair of the wall will include disassembling the existing stone wall, re-assembling the wall and restoring the roadway. This work will stabilize the area to meet current engineering standards and ensure safety to the local community that utilizes the road. The Level 33 wall is located at Mile Marker 61.5 of the Chesapeake and Ohio Canal, between locks 33 and 34.
During construction, the NPS will close Harpers Ferry Road between Hoffmaster Road and the school bus turnaround on Sandy Hook Road on March 20 (weather dependent) to public vehicles. A detour will be available along alternate public roadways – the same detour that was used during the previous Harpers Ferry Road slope stabilization project.
After a portion of the wall is disassembled, the NPS will use concrete backfill behind the wall to establish a single travel lane to facilitate passage for critical emergency management services and first responders, which will be available for use in early Summer 2023. At the end of the project, the pavement and guardrails along Harper's Ferry Road will be replaced and the road will be reopened to the public.
The towpath will remain open during this project.
