Adding a Lane to Eastbound I-66 Between the Dulles Connector Road and Fairfax Drive

About the Project

The I-66 widening project will add an additional travel lane on eastbound I-66 from the Dulles Connector Road to Fairfax Drive (Exit 71). In addition to addressing this chronic congestion point, the project will build direct access from eastbound I-66 to the West Falls Church Metro station by constructing a new ramp connection between two existing ramps (eastbound I-66 to Route 7 and the eastbound I-66 collector-distributor road adjacent to the station's parking garage) and construct a new bridge over Lee Highway (Route 29) for the W&OD Trail in the Arlington/Falls Church area. The project is expected to begin in early 2018, with the lane opening to traffic in fall 2020.

These improvements are part of VDOT’s Transform 66 Inside the Beltway project to increase the number of travelers able to move 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 U.S. Route 29 in Rosslyn during peak periods.  Toll revenues will fund increased transit service and enhanced carpool options for travelers in the I-66 Corridor.

The $85.7 million construction contract was awarded to the design/build team of Lane Construction/Rinker Design Associates in December 2017.
