Boater Advisory:
Rochambeau Memorial Bridge (I-395 HOV), Potomac River Bridge Number: 169-1

(WASHINGTON, DC) — Construction activity will continue at the Rochambeau Memorial Bridge (I-395 HOV) over the Potomac River until April 2026. Work will occur 24 hours a day, Monday through Friday.

Marine operations will include the removal and replacement of the channel timber fender system. Divers will be used to perform underwater crack repairs on bridge piers and install jacket-style repairs on dolphins.

Temporary barges will be positioned in the water to support demolition and construction efforts. These barges will reduce the navigational channel width by 20 feet. No reduction in vertical clearance will occur because of marine operations.

Topside operations will include the installation of work platforms to conduct steel, paint, and concrete repairs on the bridge structure. During installation of these platforms, wire support cables may hang up to five feet below the bottom of the bridge girders. Installation is scheduled to be completed by May 21, 2025. Once in place, the platforms will extend no more than three feet below the bottom of the girders.

Mariners are advised to proceed with caution when navigating in the vicinity of the bridge. Be alert for construction vessels, equipment, divers, and overhead obstructions. Reduced channel width and underwater activity may impact safe passage. Mariners should monitor local notices to mariners and contact appropriate authorities if needed before transiting the area.

These closures are needed for construction activities associated with the I-395 HOV Bridge Rehabilitation Project. The project consists of rehabilitation of the existing fifteen-span concrete deck slab supported on continuous steel girders, concrete beams, and reinforced concrete substructure piers carrying I-395 HOV Freeway Bridge (Bridge No. 169-1; also known as Rochambeau Memorial Bridge) over Potomac River, approach roadway work at Washington, D.C. (DC), and Arlington County, Virginia (VA) ends, streetlight upgrading work and other repairs.
