About the Project
On Nov. 8, 2019, a 36-inch Arlington County transmission water main broke under North Glebe Road, which caused subsequent damage to the roadside ditch and washed out the downstream crossing of the Potomac Heritage National Scenic Trail. Arlington County's consultant, Wetland Studies and Solutions, Inc. developed the plan(PDF, 18MB)
to repair the damaged roadside ditch, protect the existing Parkway bridge pier, and re-establish the crossing for the Potomac Heritage National Scenic Trail. This plan has been reviewed and approved by National Park Service and Virginia Department of Transportation.
The restoration includes 500 feet of the ditch downstream of the water main break site and stabilization improvements to 1,000 feet of the ditch upstream of the break to be improved with Class II riprap, as well as new guardrail installation to replace a previous guardrail and temporary jersey wall, and restoration of the Potomac Heritage National Scenic Trail, which crosses this ditch in the downstream segment underneath George Washington Memorial Parkway. The work also includes tree removal and planting/seeding, erosion and sediment control, and all other related incidental work described and required in the contract documents. Most of the work is planned to be performed at night utilizing an overnight road closure of North Glebe Road as outlined in the VDOT-approved Temporary Traffic Control Plan.
