Two Reston streets will not be part of Fairfax County's new pilot program testing 20-mph speed limits after a community survey showed residents didn't support the change.
Segments of Glade Drive and Pinecrest Road had been proposed for the county's reduced-speed pilot in December 2025. But Hunter Mill District Supervisor Walter Alcorn's office opted them out based on public feedback collected late last year, according to Fairfax County Department of Transportation (FCDOT) spokesperson Jennifer DeAngelis, as first reported by FFXnow.
DeAngelis told FFXnow that "the survey results did not show sufficient community support for reducing the speed limit to 20 on those roads." Alcorn's office decided not to proceed.
The pilot will still move forward on 10 roads in the Dranesville, Mason and Providence districts, where speed limits will drop from 25 to 20 mph. FCDOT announced the finalized list on Thursday, Oct. 15. New limits take effect as soon as signs go up, which DeAngelis said could happen as early as the week of Oct. 19.
The county's pilot study page confirms the Hunter Mill exclusion. The page says FCDOT "will continue to evaluate potential locations in the Hunter Mill District, which may be considered at later stages."
DeAngelis added that Alcorn's office may pick different roads to bring before the community in a future round of the pilot.
The 10 roads in the pilot span three districts:
Dranesville District:
- Douglass Drive from Georgetown Pike to Baron Road
- Baron Road from Randolph Road to Ingleside Avenue (small segment)
- Ingleside Avenue from Baron Road to Dolley Madison Boulevard (Route 123)
Mason District:
- Patrick Henry Drive from Leesburg Pike to Beachway Drive
- Peace Valley Lane on the west side of Justice High School
- Beachway Drive from Patrick Henry Drive to Nevius Street
- Nevius Street from Leesburg Pike to Beachway Drive
- Blair Road (segment) from Beachway Drive to Glen Carlyn Drive
Providence District:
- Flagpole Lane from White Granite Drive to Borge Street
- Bushman Drive from Borge Street to Blake Lane
FCDOT selected the roads in coordination with supervisors' offices, weighing pedestrian activity, sidewalks, crosswalks, transit stops, proximity to schools and the county's Vulnerability Index, which measures socioeconomic disparities.
The pilot traces back to a May 2024 state law that gave Virginia localities the power to lower speed limits on residential and business roads capped at 25 mph. The Fairfax County Board of Supervisors voted 10-0 in June to authorize the program, which is expected to eventually cover all nine magisterial districts. The county estimated signage costs at about $24,000 when the board approved the program, based on a plan covering one road per district.
No physical changes to the roads are planned beyond new signs.
FCDOT plans to collect speed and volume data before and after the pilot, with an evaluation period running into early 2027. After the first three zones are up, the department said it will coordinate with remaining board offices to expand the study.
Glade Drive and Pinecrest Road will stay at 25 mph while the county tests slower speeds elsewhere this fall.
