I-66 Spot Improvements - Spot 2
|Westbound from Washington Boulevard in Arlington to the Dulles Access Road in Fairfax|
Project at a Glance
About the Project
This project will connect 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 will also be constructed, with full-strength pavement capable of carrying traffic during emergencies.
A similar 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.
A third project between Lee Highway and Glebe Road is planned but not yet fully funded for construction.
No daytime traffic impacts are expected as crews will work behind barriers.
All lane closures will be done at night from 10 p.m. to 5 a.m. Through early summer, only occasional lane closures are expected, with nighttime lane closures increasing during the summer.
Bridge widening work has begun at Williamsburg Boulevard and Westmoreland Street. This work will require occasional lane closures, resulting in the presence of flaggers and two-way, one lane traffic on these roads.
Drainage improvements have continued along both the median and right shoulder of I-66 westbound. Additionally, soundwall construction has continued along the right shoulder of I-66 westbound.
Crews began installing soundwall panels at the west end of the Dulles Airport Access Road (DAAR) ramp. Over the next couple of weeks, crews will install soundwall panels where they have already installed posts, working from west to east.
Soundwall construction continues westbound. The crew is working east of Great Falls St. toward Williamsburg Blvd. Soundwall panel installation begins soon, starting at the ramp to the Dulles Airport Access Road and working east along westbound I-66. Drainage improvements continue along the right shoulder and work along the left shoulder will begin this month.
