Transportation Improvements Will Enhance All Modes of Travel at the Site

One of the most iconic and prominent sites in the region, located at the gateway into Virginia from Washington, DC, gained approval on Tuesday, March 24, 2020 from the Arlington County Board of Supervisors to undergo a massive redevelopment.

The Key Bridge Marriott site will include a new renovated hotel including upgraded ballroom/conference facilities, a new restaurant, and large promenade providing unparalleled views of the Potomac River and Georgetown, just across the river in Washington. In addition to the renovated hotel, the redevelopment will also include the addition of three residential buildings containing a mix of rental and for-sale units.

Located within the Rosslyn neighborhood and adjacent to the Custis Trail, one of the most heavily traveled bicycle and pedestrian routes in the Washington DC metropolitan region, the redevelopment will embrace multimodal transportation. The site redevelopment will include a range of transportation options, including:

  • A new network of trails for both pedestrians and bicyclists through the promenade as well as the extension of Nash Street and construction of Meade Street.
  • Two proposed streets that will be “shared-streets” which place equal importance on all modes of travel.
  • A new Capital Bikeshare station, adjacent to the Custis Trail filling an existing void in the northern portion of the Rosslyn neighborhood.

W+A’s Work on the Transportation Aspects of the Redevelopment

A TDM (transportation demand management) statement was also provided to identify ways to reduce impacts and promote transit as Rosslyn continues to grow. Our team presented at the Arlington County Transportation Commission decision hearing where the Commission voted to unanimously support the application. 

We are proud and grateful to be part of this welcomed addition to the Rosslyn neighborhood of Arlington County that will make full use of all possible modes of transportation.
