I-66 Eastbound Widening Inside the Beltway

I-66 is one of just two main highways providing access to Washington, D.C., and the surrounding areas. As part of the Virginia Department of Transportation’s Transform 66 program, which aims to help move more people through the busy I-66 corridor, Lane added a through lane along approximately 4 miles of eastbound I-66 from the Dulles Connector Road (Route 267) to Fairfax Drive (Route 237) in Arlington County.

Overview

The highway widening was needed to accommodate residents of the Northern Virginia area who are traveling into Washington, D.C., and to address the increasing congestion from reverse commuters who live in Arlington, Alexandria, and Washington, D.C., and commute to jobs in the Tysons and Dulles Corridor areas.

The completed project helps move more commuters, reduces congestion, and provides an alternate travel option. Construction started in mid-2018 and was completed in September 2021.

Technical Highlights

The project included:

  • exit ramp modifications
  • bridge widening and rehabilitation
  • construction of a new above-grade pedestrian crossing of the Washington & Old Dominion Trail biking trail
  • installation of new sound walls and lighting
  • storm water management and drainage improvements
