Full Closure of Westbound Interstate 66 Overnights Next Week
Dulles Corridor Metrorail construction will implement a full closure of westbound I-66, between Route 267 and Route 7, from 11 p.m. to 5 a.m. Sunday, July 8, through Friday, July 13. These closures are necessary to install acoustical barriers on the new Metrorail aerial guideway (flyover bridge) that crosses the highway. Traffic is not allowed to flow under active construction for public safety reasons.
Please follow the detour below:
Detour: From westbound I-66, take Exit 67 to westbound Route 267, take Exit 19A to southbound Route 123, exit onto southbound I-495, then take Exit 49 to westbound I-66.
Police will be onsite for motorist safety during the closures.
