Plans for five residential buildings and a new hotel have been filed at the vacant Key Bridge Marriott site in Rosslyn.
The proposed “Potomac Overlook” development at 1401 Langston Blvd, announced today (Tuesday), would include 1,775 residential units, a 200-room hotel and underground parking on the empty 5.5-acre lot overlooking the Potomac River.
“The Potomac Overlook plan features a network of green spaces, pathways, and view corridors leading to a sweeping panorama of the Potomac River, National Park Service land, the U.S. Capitol, and Georgetown, all woven between a series of thoughtfully spaced, tall slender buildings intended to maximize public view corridors,” a press release says.
The project is described as a “transit-oriented development” with “substantial publicly accessible open space,” including “seating, landscaping and public art” and paths connecting to the Custis Trail and Gateway Park.
Quadrangle Development Corporation, a D.C.-based real estate company serving as the development consultant, announced the project on behalf of a lender that “holds the defaulted first-lien mortgage debt on the land.”
The owner of the property is still listed on property records as KBLH, a subsidiary of Woodbridge Capital Partners, which previously abandoned plans for the Key Bridge Marriott site amid financial distress. Since those plans expired in July, the new proposal will have to follow the typical site plan review process in order to receive approval from the Arlington County Board.
Quadrangle filed plans for the property on Dec. 22, according to the press release, but the application was not available in online permitting records as of today (Tuesday).
“This is an exceptional opportunity to activate an incredible property at the center of so much activity in Rosslyn and the entire DMV,” said Quadrangle President Christopher Gladstone. “Our design purposefully invites the public in to enjoy this unique water view property offering outstanding views over the Potomac River and toward the Nation’s Capital.”
Quadrangle plans to undertake the review process for the project throughout 2026.
The closed hotel that previously stood on the property was demolished last year following years of infamy, including a large police operation to remove squatters in 2023 and the structure being declared a “public nuisance” in May 2024.
