Transform 66 Inside the Beltway

VDOT’s Transform 66 Inside the Beltway program to move more travelers efficiently through the I-66 corridor during peak periods. The Transform 66 Project includes Express Lanes operation (carpool, express buses, and dynamically-priced tolls for solo drivers) on I-66 between the Beltway and Route 29 in Rosslyn during peak periods. Toll revenues are being used to fund increased transit service, enhanced carpool options for travelers, and other multimodal improvements in the I-66 Corridor. Construction of the project began in June 2018, and the new lane opened to traffic in December 2020. Final elements of the project were completed in August 2021.


The I-66 Inside the Beltway Eastbound Widening Project aimed to:

  • Reduce traffic bottlenecks by adding a travel lane on eastbound I-66 between the Dulles Connector Road and Fairfax Drive (Exit 71).
  • Provide a new ramp-to-ramp direct access connection from eastbound I-66 to the West Falls Church Metrorail Station at the Route 7 (Leesburg Pike) Interchange.
  • Provide a new bridge for the W&OD Trail over Route 29 (Lee Highway), providing safe access for cyclists and pedestrians.
