South Four Mile Run Drive from South Oakland Street to Shirlington Road, near Jennie Dean Park
This project is in design and being coordinated with the Jennie Dean Park redevelopment.
About the Project
This section of South Four Mile Run Drive will pilot a roadway reconfiguration identified in the Four Mile Run Valley Area Plan.
The pilot project can be implemented using low-cost, interim measures to facilitate easy installation and evaluation. This pilot, and the data collected, will help determine the viability of longer-term roadway reconstructions that could potentially add sidewalks, landscaping and green infrastructure, as appropriate.
The County’s adopted Vision Zero Action Plan, adopted in 2020, highlights South Four Mile Run Drive as part of the County’s High-Injury Network (i.e., corridors in the county with higher densities of crashes resulting in a serious or fatal injury) and identifies crash hot spots including the intersection of South Four Mile Run Drive and South Walter Reed Drive and Shirlington Road and 27th Street South, which are located on either ends of the pilot corridor.
County staff will assess and address safety issues along South Four Mile Run Drive as part of this project, as well as other projects and initiatives, to continue to work toward safer conditions throughout the corridor.

- Support Jennie Dean Park renovation by maximizing on-street parking while also ensuring safety for pedestrians and maintaining appropriate traffic flow.
- Provide a continuous pedestrian pathway on the north side of S Four Mile Run Drive.
- Enhance ramps and shorten pedestrian crossing distances at Shirlington Road and S Nelson Street to increase pedestrian safety and access to Jennie Dean Park, nearby trails and other destinations in Green Valley and Shirlington.
- Reduce vehicle speeds (currently averaging about 10MPH above the speed limit) to improve safety for all road users.
- Improve safety and accessibility to nearby bus stops (ART Routes 75 & 87, Metro Routes 10B, 23A/B/T) for transit users.
In order to achieve pilot project goals, a roadway reconfiguration is necessary for this section of Four Mile Run Drive, as indicated in the Four Mile Run Valley Area Plan. Providing one travel lane in each direction provides the roadway space to achieve the project goals of:
- Maintaining adequate traffic flow
- Maximizing on-street parking
- Improving crossings and providing new pathways for people walking, biking and accessing transit
- Reducing excessive vehicular speeding
Community Engagement Process
Concept Design Meeting – July 2021
Based on guidance from existing plans, the project team will share a base concept design that includes potential options on pedestrian pathway connectivity, an additional crosswalk location and different parking use-type scenarios.
- Learn about project goals and existing plan guidance
- Review the project concept and options
- Share your feedback
Input gathered will hele evaluate and refine the final concept design.
Final Concept and Implementation – Fall 2021
Based on community feedback and existing plan guidance, a final concept will be communicated and impacts of implementation will be shared.
- Hear how community feedback helped shape the final concept
- View the final concept online
- Learn more about what impacts to expect during implementation
Additional community engagement activities:
- Staff provided a general timeline update to the Green Valley Civic Association in June 2021
