A new ramp and flyover bridge connecting the eastbound Dulles Airport Access Highway to I-495 will open to traffic on Saturday, September 8, 2012. The ramp provides a direct connection to the northbound and southbound Capital Beltway (I-495), improving safety and convenience for traffic near the interchange.
Drivers on the Access Highway will no longer need to exit to the Dulles Toll Road and cross multiple lanes of traffic to reach the Beltway. New overhead signage on the Access Highway will direct drivers to the new ramp.
Airport traffic destined for Route 123 or the 495 Express lanes (opening later this year) will continue using the existing ramp to the eastbound Dulles Toll Road near the main toll plaza.
