About the Study

U.S. Route 1 (Richmond Highway) is a major north-south arterial and part of the National Highway System. Regionally, Route 1 is a primary arterial road connecting Washington, D.C., Arlington County, the City of Alexandria, and southern suburbs including Fairfax and Prince William counties. Route 1 carries more than 45,000 vehicles per day in the Crystal City and Pentagon City area.

In late 2018, with the announcement of an agreement to bring Amazon's new corporate headquarters to Crystal City, the Commonwealth of Virginia identified improvements to Route 1 as one of five transportation projects to be fully or partially funded by the Commonwealth. The Commonwealth’s commitment to Amazon is to improve safety, accessibility, and the pedestrian experience crossing Route 1.  

The purpose of this study is to identify enhanced multimodal connectivity and accommodations along and across Route 1 in Crystal City, to meet the changing transportation needs of this growing urban activity center. The need for this study is two-fold:

  • Multimodal transportation demand is increasing from the creation of an additional Amazon U.S. Headquarters (HQ2) and other ongoing development in the Crystal City and Pentagon City area
  • These areas are already heavily developed with limited space for expanding the footprint of the transportation network

The study on Route 1, from approximately 12th Street to 23rd Street South, explored an at-grade urban boulevard, but also reviewed and compared potential improvements to the current elevated condition, and the elevated urban boulevard described in the Crystal City Sector Plan. Ultimately, the study aims to provide sufficient information to make the best decision on a future project on Route 1 in Crystal City. 

At this time, no construction funding has been allocated, so this study has not set design or construction dates. 

This study is being performed in close coordination with Arlington County staff and other local and regional stakeholders.

Study Goals

Safety: Improve multimodal safety for pedestrians, bicyclists, micro-mobility modes, transit and vehicles along and across Route 1

Multimodal accessibility and accommodation: Increase multimodal accessibility and accommodation along and across Route 1

Transit effectiveness: Make transit more accessible, reliable, and convenient

Vehicular operations: Maintain an appropriate level of vehicular operation and accommodation along Route 1 and on intersecting streets: 15th Street, 18th Street, 20th Street, and 23rd Street

Environmental: Preserve, protect, or enhance the built, natural, visual, and social environments

Urban Fabric: Integrate Route 1 within the context of Crystal City and Pentagon City as a multimodal urban boulevard design consistent with context of the surrounding existing and future built environment

Community Engagement

The study team has engaged community partners during the study process. Beginning in fall 2020, the team reached out to civic associations, Arlington County advisory groups, and the National Landing Business Improvement District (BID) to create a task force to receive community input. Four meetings were held with the task force.

Three opportunities for the general public to provide feedback also occurred during the feasibility study. Sign up at the right to receive updates. Formats were developed to reach, engage and accommodate as many members of the public as possible in light of the current pandemic.
