The plan is to create a one mile long auxiliary lane by connecting the Washington Blvd on-ramp to the off-ramp at the Dulles Airport Access Road. Workers will also construct a new 12-foot wide shoulder with full-strength pavement capable of carrying traffic during emergencies. Today, VDOT awarded a $23 million contract for the project to The Lane Construction Corporation.
A similar project was completed in 2011, when the acceleration lane at the Fairfax Drive on-ramp was extended to the deceleration lane at the Sycamore Street off-ramp. That created a continuous lane that stretches for nearly two miles.
