The I-66 widening project will add an additional travel lane along approximately four miles of eastbound I-66 from the Dulles Connector Road to Fairfax Drive (Exit 71). Adding another travel lane to this portion of eastbound I-66 helps address a choke point that snarls traffic during morning rush hour, evenings, and weekends. The Eastbound Widening Project will also replace approximately 4,300 feet of dilapidated noise walls that align this section of I-66, and add up to 9,400 feet of new noise walls, benefitting properties adjacent to the highway. The project includes ramp modifications at Exits 69 and 71 and bridge widening, rehabilitations and/or repairs on I-66. Construction of the project will occur largely within VDOT’s right of way, however, some minor temporary construction easements, permanent easements, and right-of-way will be needed from approximately 10 parcels, all of which are either government agencies or commercial properties. The easements and right-of-way required are primarily for construction of new noise walls and the proposed W&OD Trail Bridge over Lee Highway.
The additional travel lane opened on I-66 East on Dec. 11, 2020.
These improvements are part of 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 U.S. Route 29 in Rosslyn during peak periods. Toll revenues will fund increased transit service, enhanced carpool options for travelers, and other multimodal improvements in the I-66 Corridor.
The $85.7 million construction contract for the I-66 Eastbound Widening Project was awarded to the Design-Build team of Lane Construction Corporation/Rinker Design Associates in December 2017. The project is funded through a combination of federal and state sources, including bond proceeds, priority transportation funds, and dedicated state funding.
Construction of the project began in June 2018, and the new lane will open to traffic in December 2020.
