Project at a Glance
About the Project
This project will construct an auxiliary lane connecting the on-ramp from Route 29 (Lee Highway) Exit 72 to the off-ramp to North Glebe Road (Route 120) on westbound I-66. The project will include sound walls at locations meeting the federal criteria and approved by adjacent benefited property owners. No right of way acquisition is anticipated.
This is the third and final project in a series of spot improvements on westbound I-66. The first project was completed in December 2011, extending the acceleration lane at the Fairfax Drive on-ramp (just west of George Mason Drive) to the deceleration lane at the Sycamore Street off-ramp, creating a continuous auxiliary lane of almost two miles between the two ramps. A new 12-foot-wide shoulder was also constructed. The second project was completed in June 2016, connecting the Washington Boulevard on-ramp to the off-ramp at the Dulles Airport Access Road, creating a one-mile stretch of auxiliary lane to improve operations and safety on westbound I-66. A new 12-foot-wide shoulder was also constructed, with full-strength pavement capable of carrying traffic during emergencies.
