South George Mason Drive Multimodal Transportation Study



The study's third phase began in September 2022, and includes the introduction of preliminary concept designs for major intersections along the study corridor. The project team is preparing for public meetings and gathering feedback on the concepts to be a part of the Study's report.

About the Project

The South George Mason Dr. Multimodal Transportation Study will review this key corridor from Route 50 to the Arlington/Fairfax line to identify improvements that deliver the vision, goals, and prior planning of Arlington County’s Master Transportation Plan (MTP).

The study will develop a corridor-wide profile and initial concepts for each segment, and further develop a preliminary design concept for the segments located between Columbia Pike and the County line for use in upcoming grant funding applications.

Updated Project Schedule:

  • Kick-off and public engagement on your experience today* - March-May 2022
  • Corridor-wide analysis and concept development* - June-August 2022
  • Intersection analysis and planning* - September 2022 - January 2023
  • Drafting the Study - December 2022 - January 2023
  • Finalizing the Study - January 2023 - February 2022

* includes a public engagement check-point

Public Process

There will be multiple public engagement opportunities throughout the study process to gather community feedback and share what we've learned during the analysis phases of the study.

All public engagement opportunities will be announced in advance and information will be shared on this page and through the Southern Arlington/Four Mile Run Transportation Update email newsletter.

Fall 2022 - Preliminary Intersection Concepts

In September 2022, the project team began the third phase of the study, focused on the major and minor intersections along the study corridor. Using information and public input gathered in the first two phases of the study, we developed preliminary intersection concepts for three major intersections, and highlighted design tools that could be used elsewhere in the corridor.

There are three ways to share your input on the intersection concepts: 

Attend the virtual public meeting

Intersection Concepts Virtual Community Meeting

  • Date: Wednesday, December 7, 2022

Share your input in the online feedback form

The online feedback form will be open from December 7, 2022 to December 28, 2022. 

Visit us at a Pop-Up Engagement Event

The study team will be holding pop-up engagement events in the community to provide more opportunities to share their input on the intersection concepts. These events will occur in December 2022. More information will be available closer to the kick-off of public engagement on December 7.

Summer 2022 - Preliminary Corridor Concepts

In July 2022, the project team launched the second round of public engagement, focused on sharing the two preliminary conceptual alternatives for each segment of the project corridor using what we learned from the first phase of public engagement and initial analysis of the corridor. This engagement opportunity included a virtual community kick-off meeting to re-introduce the study, covered what we heard in the first phase of public engagement and shared two initial concepts for each of the three segments of the project corridor.

There were two ways for the community to share input on the concepts: an online feedback form and an in-person Community Workshop & Open House. Both options highlighted the benefits and challenges of each of the design concepts, highlight how these concepts incorporated what we've learned so far in the study, and allowed people to share their thoughts on the future of S. George Mason Drive.

Spring 2022 - Study Kick-Off and Understanding Your Experience Today

In the spring of 2022, the County kicked off the study’s public engagement with a virtual community meeting highlighting the study area, the existing conditions on the corridor and the planning context for the study. At the same time, the County opened an interactive online map to gather and assess the community’s thoughts on and experiences with the existing conditions on S. George Mason Drive. The interactive map included questions about travel habits, demographics, safety, and allowed respondents to place pins along the project corridor to note concerns, ideas, likes, dislikes, and general comments. 

The project team also held two in-person walking tours. The first walking tour focused on existing conditions and opportunities for improvement along S. George Mason Drive from Four Mile Run Drive to the County Line. The second walking tour focused on existing conditions and opportunities for improvement along S. George Mason Drive from Columbia Pike to Arlington Boulevard. Spanish/English translation was provided at the walking tours.
