Weekend Road and Rail: Inauguration closures, roadwork planned for I-66 & I-495

Starting Friday, and lasting through Thursday, Jan. 21, Metro will close 13 stations inside a security perimeter that has been established for President-elect Joe Biden’s inauguration, with 11 stations closing Friday and another two stations closing Saturday.

Downtown, federal authorities locked down a large swath of roads earlier than originally planned after the Jan. 6 deadly riots and before the Jan. 20 inauguration.

Overnight stops are planned for I-66 and work is planned for the Beltway in Maryland.


Metro will close 13 stations inside the security perimeter, with 11 stations closing on Friday and two additional stations on Saturday and continuing through the end of service on Thursday.

Beginning Friday and continuing for six days, trains will operate Saturday service frequencies — every 12 minutes on the Red Line and every 15 minutes on all other lines — bypassing all closed stations while residents are urged by officials to stay out of the downtown area.

In addition, 26 bus routes will be detoured around this security perimeter from Friday through Thursday.

Metrobus will operate normal service on weekdays and weekends to accommodate customers making trips outside the zone, with the exception of Jan. 20, when buses will operate on a Saturday schedule.

Saturday through next Friday, Metro has closed 13 stations inside the security perimeter. This means all trains will be bypassing the following stations:

  • Red Line: Farragut North, Judiciary Square and Union Station
  • Yellow/Green:  Archives
  • Blue: Arlington Cemetery
  • Blue/Orange/Silver: Farragut West, McPherson Sq., Federal Center SW. Capitol South, Smithsonian, and Federal Triangle
  • Metro Center and Gallery Place to re-open Friday morning



On Interstate 66 approaching Route 123 (Chain Bridge Road) all lanes will close nightly this weekend, Friday through Sunday, to allow demolition of the old northbound Route 123 bridge over I-66 as part of the Transform 66 Outside the Beltway Project.

All traffic on I-66 will be detoured around the closure using the ramps and service road for Route 123. Route 123 will remain open and drivers traveling through this interchange during the work closures can expect delays.

Crews will begin setting up a concrete barrier with a flagging operation daily between 8 a.m. and 4 p.m. Two lanes will be maintained throughout the duration of the project and residents will be able to access both MD-450 and local roadways during construction.

Portable variable message signs have been placed along MD-450, advising area residents and motorists of the upcoming work. Motorists can use MD-214 Central Avenue and US-50 John Hanson Highway as alternate routes to avoid delays.


In the District, it’s all about closures and security for the upcoming inauguration. In conjunction with Metro, officials have set up a security parameter to include closures around the Capitol Building and the National Mall.
