If you or your loved ones are flying out of Dulles International Airport this weekend, you'll want to be alert for possible traffic delays.
A westbound closure of the Dulles Airport Access Highway is scheduled throughout the weekend for work related to the Washington Metro's Silver Line extension project.
From the Capital Beltway toward the Dulles Airport, all westbound traffic will be diverted onto the Dulles Toll Road near Hunter Mill Road. Drivers headed for Dulles Airport will be able to re-enter the Dulles Access Highway near Route 28.
A similar closure caused significant delays for afternoon and evening weekend travelers last month. The longest backups in the access lanes formed by about 3 p.m. and were worst on Sunday. The Dulles Toll Road wasn't affected. Some travelers reported sitting in bumper-to-bumper traffic in the access lanes for nearly an hour.
During this busy travel weekend, rail project officials told WTOP that if major delays form, they are prepared to reopen the road early. The closure is scheduled to be in effect from 10 p.m. Friday through 5 a.m. Monday.
