395 Express Lanes

Note: The westbound Seminary Road service road over I-395 will be closed as early as 10 p.m. Tuesday night, March 31 until midnight Saturday night, April 4.

The westbound Seminary Road service road over I-395 will be reduced to one lane from 10 p.m. Monday night, April 6 to 5 a.m. Thursday morning, April 9.

The 395 Express Lanes are closed on weekends until late spring 2020 from 11 p.m. Friday nights to 4 a.m. Monday mornings for various construction work. 

The 395 Express Lanes opened to traffic Nov. 17. 395 Express Lanes Opening Fact Sheet

This project extended the 395 Express Lanes about eight miles north, from the Turkeycock Run interchange near Edsall Road to the vicinity of Eads Street in Arlington. To learn how the 395 Express Lanes work, visit www.expresslanes.com/395.

The two High Occupancy Vehicle (HOV) lanes that existed prior to construction were converted to express lanes and a third lane was added, providing three reversible express lanes.

The improvements are being mostly built within the existing footprint of the I-395 HOV lanes.

In November 2015, the commonwealth signed a framework agreement establishing that the 395 Express Lanes extension be done by Transurban under the current 95 Express Lanes Comprehensive Agreement with VDOT.

New bus and slug lanes at the Pentagon South Parking Lot opened in May 2019.

There will be a dedicated annual payment by Transurban for transit services and multimodal strategies identified in a study led by Virginia’s Department of Rail and Public Transportation.

Vehicles with three or more people can use the express lanes free, while vehicles with fewer than three people can choose to pay a variable toll and use the express lanes.

Project information is also available on the Transurban 395 Express Lanes webpage.

Benefits 

This project will:

• Provide new travel options for single-occupant drivers.
• Provide quicker access to the Pentagon and Crystal City through interchange improvements at Eads Street.
• Fund additional transit options for commuters through $15 million a year from toll revenues.
• Ease congestion with a new fourth regular lane southbound Duke Street to Edsall Road.
