About the Project
In 2015 the County Board adopted a Rosslyn Sector Plan that included a multimodal transportation vision set forth by the community. In 2017 the County’s Transportation Division, in partnership with the Rosslyn Business Improvement District (BID), started the Core of Rosslyn Transportation Study to assess the feasibility and potential impacts, through 2030, of the proposed Sector Plan changes to the Rosslyn transportation network.
Collaboration between the County and the BID also included short-term roadway enhancements to improve safety and circulation using low-cost, quick-build strategies.
Core of Rosslyn Transportation Study
This study examined the feasibility and potential impacts of permanent changes to the street network in the core of Rosslyn, with the goals of improving safety and accessibility for all users – those walking, biking, using transit and driving.
The study’s goals included:
- Evaluating multimodal design concepts (Concept 1 then Concept 2)
- Measuring how each concept achieves the Sector Plan goals
- Engaging the public and stakeholders
- Adopting a 2030 Preferred Alternative concept composed of individual projects that will move through the County’s design process
- Sequencing those projects to create a fluid network transition into 2030
- Identifying improvements that go beyond 2030 to continue realizing the Rosslyn Sector Plan in the future
- October 2017 project kick-off: Project scoping, data collection, existing conditions analysis.
- April 2018 public meeting: Review of existing conditions and assumptions for 2030 redevelopment and infrastructure forecasts.
- October 2018 public meeting: Discuss pros and cons of Concept 1 – an alternative including all of the infrastructure changes listed in the Sector Plan based on what could be realistically built by 2030.
- March 2019 public meeting: Discuss pros and cons of Concept 2 – an alternative that incorporates public feedback and lessons learned from Concept 1.
- June 2019 public meeting: Review and discuss the Preferred Alternative and implementation.
- Summer 2019: Final Preferred Alternative and supporting documentation available online.
- Fall-Winter 2019: Integration of Preferred Alternative projects into the County budgeting process.
- 2020 and Onward: Implementation of projects.
Existing Conditions Analysis
The project team finalized the existing conditions analysis in summer 2018. The following documents comprise the existing conditions report:
- Core of Rosslyn Transportation Study Final Existing Conditions Report
- A – Traffic Data
- B – Forecasting and Traffic Operations Analysis Framework
- C – Travel Demand Model Validation and Data Collection Summary
- D – Multimodal Measures of Effectiveness
- E – VISSIM Model Calibration Summary
- F – Synchro Model Measures of Effectiveness
- G – VISSIM Model Measures of Effectiveness
- H – Core Rosslyn Reconfiguration Area Crash Statistics
The project team arrived at a Preferred Alternative in June of 2019 that was provided to the community for review and comment. The Preferred Alternative applies lessons learned and public input from Concepts 1 and 2 to better balance multimodal operations.
The Preferred Alternative includes the following major projects that stem directly from the Rosslyn Sector Plan to be constructed over the next 10 years:
- Removal of the Fort Myer Drive Tunnel to increase pedestrian crossing options (access to Metro) over Fort Myer Drive and to help reduce vehicle speeds in the Rosslyn urban core.
- Incremental conversion of Fort Myer Drive to a two-way street once the tunnel is closed.
- Emphasis on enhancing the bicycle network within the Rosslyn core by including continuous, protected bicycle/scooter facilities on Fort Myer Drive, North Lynn Street, Nash Street, and Wilson Boulevard. These connections within the Rosslyn core will also serve to enhance connections to major regional bike routes.
- Enhancing the pedestrian experience through the removal of slip lanes, enhancement of 18 existing or new crosswalks, and inclusion of wider sidewalks.
- Reconfiguration and signalization of the intersection of westbound US-50 and Meade Street to allow for northbound traffic flow on Fort Myer Drive and to improve pedestrian and bicycle access.
Short-term Roadway Enhancements
Concurrent with the transportation study, we are considering short-term, lower-cost opportunities to improve the overall street and sidewalk experience in Rosslyn. The effort began with a community workshop on March 4, 2017, where we introduced the concept of Tactical Urbanism – the use of short-term strategies to test long-term transportation solutions and capitalize on place-making opportunities.
Examples of short-term enhancements include installing temporary curb extensions to shorten the distance one has to walk when crossing a street, and converting some underutilized street space for pedestrian use.
In fall 2017, Arlington County and the Rosslyn BID began implementing short-term strategies identified in the March 2017 workshop.

June 2019 - Core of Rosslyn Study Public Meeting #4
At the fourth public meeting we presented the Preferred Alternative, which further refined Concept 2 and proposed implementation phasing.

- Summary of the study process and how the community has been involved
Share your feedback on the Preferred Alternative and implementation phasing by July 2.
March 2019 - Core of Rosslyn Study Public Meeting #3
At the third public meeting we presented Concept 2, which incorporates public feedback and lessons learned from the first concept, includes most changes listed in the Sector Plan, but keeps Lynn Street and Moore Street as one-way.

October 2018 - Core of Rosslyn Study Public Meeting #2
The study's second public meeting shared the results of Concept 1, which uses street network recommendations from the 2015 Rosslyn Sector Plan and analyzes how Rosslyn streets would perform if the recommendations are implemented.
April 2018 - Core of Rosslyn Study Public Meeting #1
The first public meeting for the study presented the baseline analysis of existing transportation conditions in the Rosslyn core study area.
September 2017 - Rosslyn Transportation Open House
At this open house in September 2017, staff from the County and the Rosslyn BID provided details on recent street enhancements and how they will inform the transportation study examining permanent changes to the street network in the core of Rosslyn.
March 2017 - Rosslyn Transportation Workshop
The Rosslyn BID and Arlington County hosted a community workshop in March 2017 to envision how vehicles, buses, bikes, and pedestrians can better use streets in the core of Rosslyn.
Participants, representing residents, local businesses, developers, visitors, commuters and transportation officials, examined some of Rosslyn’s busiest intersections and worked together to come up with pilot strategies to make them flow better.
Stakeholder Advisory & Strategy Groups
The County’s Transportation Division created a Stakeholder Advisory Group and Strategy Group to aid in identifying and developing improvements to the street network in the core of Rosslyn.
Advisory group members, which include residents, business representatives, and the Rosslyn BID, attended meetings at key milestones throughout the transportation study process, and shared information about these efforts with their respective community networks.
