Note: The second community meeting will be held Thursday, Oct. 18 at 7 p.m. at McLean High School, 1633 Davidson Road, McLean, VA 22101.

VDOT is seeking the community's input on some of the longer-term proposals, including a potential pilot project to evaluate limiting access to the ramp from Georgetown Pike to northbound I-495 during weekday afternoon/evening periods. Email comments to, please include “McLean Traffic Analysis” in the subject line.

As with the community meeting in August, a comment period will follow the Oct. 18 meeting. VDOT looks forward to partnering further with the community on this issue. 

About the Study

Since 2017, VDOT and Fairfax County have worked with the community to identify both short-term, intermediate and long-term solutions to mitigate potential congestion solutions for neighborhoods near I-495 (the Capital Beltway).

Short-term solutions that have been implemented to mitigate neighborhood congestion include installation of temporary traffic monitoring cameras that are linked to 511, larger “Do not Block the Intersection” signs, additional “No U-turn” signs, orange flags placed on the signs, increased police enforcement to prevent illegal traffic movements at the intersection, widening the shoulder on north side of Georgetown Pike at the intersection of Balls Hill Road and Georgetown Pike for increased Police enforcement and painting the box approaching the intersection to encourage drivers not to stop in the middle of the intersection.

Intermediate solutions include forming the McLean Traffic Advisory Group (MTAG) that represents neighborhood traffic issues to communicate with neighbors, initiating cut through restriction process with Dead Run/Carper neighborhood, assessing the concept of improvements at Balls Hill Road and Georgetown Pike intersection, reviewing Douglass Drive and Georgetown Pike intersection, additional coordination with local stakeholders and Fairfax County Public Schools to improve safety around Cooper Middle School, and reviewing other possible alternatives to improve congestion in the area.

Long-term solutions include continued coordination with Maryland on proposed improvements to the American Legion Bridge, which include the start of an environmental analysis on plans to study extending the I-495 Express Lanes by approximately three miles from the I-495 and Dulles Toll Road interchange to the vicinity of the American Legion Bridge and Maryland line.

The project team has presented information to the public at meetings held on Sept. 18, 2017 and May 9, 2018. Meeting materials can be viewed below under "Resources" below.
