I-395 HOV/Transit Ramp
|Ramp to Seminary Road in the City of Alexandria|
Project at a Glance
Beginning as early as Monday, March 3, the Virginia Department of Transportation (VDOT) will begin construction on a new auxiliary lane on northbound I-395 between Duke Street and Seminary Road. The new lane will provide easier access to the Department of Defense's Mark Center building, and will help improve traffic flow along I-395 North.
Drivers should expect daytime lane closures during non-rush hours on the right lane of I-395 North to accommodate this work. Scroll down for Traffic Impacts.
About the Project
This project will construct a reversible High Occupancy Vehicle/Transit ramp on I-395 at Seminary Road. The ramp will provide improved access for HOV and transit users working at or near the Mark Center site. The Mark Center is a new Department of Defense facility at Seminary Road and I-395 that holds 6,400 employees.
The Department of Defense has allocated $20 million to construct short-term improvements developed by VDOT, which include a turn lane, ramp widening and pedestrian improvements on Seminary Road, Beauregard Street and I-395/Seminary Road.
Estimated Project Costs
The Commonwealth has allocated $80 million for the construction of a reversible HOV/Transit ramp on I-395 at Seminary Road.
Begin construction - late 2013/early 2014
Estimated completion date - Spring 2016
I-395 North Auxiliary Lane
This project will also include one additional northbound auxiliary lane on I-395 connecting the northbound on-ramp at Duke Street (Route 236) to the northbound off-ramp at Seminary Road.
This 0.8-mile auxiliary lane will ease congestion where motorists enter and exit I-395.
Noise Barrier Walls
An in-depth noise study has been conducted for this project finding that noise walls would benefit multiple areas along the project corridor. VDOT’s policy on potential sound walls involves significant public input. Residents of the benefited areas are eligible to vote on the decision to place sound walls or not. These residents will receive a survey through certified mail. We are anticipating the surveys to be sent out by the end of the year. For more information on VDOT’s sound abatement policies, follow the links on this page to VDOT’s sizeable collection of noise abatement resources and a brief description of the voting procedure for proposed noise barrier walls.
The voting results shown in the table, linked below, represent the response received by VDOT for the initial ballot mailings regarding the proposed noise walls along I-395 in the City of Alexandria. These initial mailings were sent out on December 2, 2013 and were to be postmarked by January 2, 2014. Some of these certified mailings were temporarily lost by the USPS so a second mailing was sent by first-class mail to the affected residences and their postmark date was pushed back to January 8, 2014 to allow enough time to respond. The USPS later found the initial mailings and sent them out as well.
Due to a low response rate from the surveyed communities, VDOT determined it was necessary to send out a second mailing to those residents who had not yet responded. Additional outreach, such as second mailings, is recommended by the VDOT Highway Traffic Noise Impact Analysis Guidance Manual. These second mailings were sent out on January 28, 2014 and the postmark date for this final ballot is set as February 11, 2014. Once these votes have been returned and the data from both mailings reviewed, a determination on whether or not to build the proposed noise walls will be made in accordance with the Manual.

Traffic Shift on I-395 North:
Scheduled for the second week of March, the existing three northbound lanes on I-395 will be shifted to the left to allow for construction access. This new alignment will remain in place until the new auxiliary lane is completed in late 2014. All exit and entrance ramps will remain open; drivers should expect reduced shoulders.
Nighttime lane closures will occur on I-395 North between the hours of 9:30 p.m. and 5:00 a.m. for restriping of the temporary alignment, to install construction signage and place concrete barriers throughout the work area.
The northbound I-395 auxiliary lane is scheduled to open to traffic in late 2014, in conjunction with the nearby I-95/395 Express Lanes. Construction of a new HOV ramp linking the I-395 HOV lanes to Seminary Road will also be underway in the coming months, with expected completion in 2016.
The shoulder strengthening along the inside shoulder of northbound I-395 has been completed. There will be no more work done requiring lane closures or causing other traffic impacts until after the new year.
