Update

Beginning in March 2014, 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 (see fact sheet).

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

I-395 HOV Ramp

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.

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.

Estimated Project Costs

The Commonwealth has allocated approximately $80 million for the construction of a reversible HOV ramp on I-395 at Seminary Road and I-395 north auxiliary lane.

  • HOV Ramp - $60 million
  • Auxiliary Lane - $20 million
  • Total - Approximately $80 million

Anticipated Schedule

Begin construction - March 2014

Auxiliary lane open to traffic - December 2014

Estimated completion date - Spring 2016

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.

First Round Voting Results

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 Impacts

Traffic Shift on I-395 North:

The existing three northbound lanes on I-395 will be shifted to the left to allow for construction access. This new alignment, once shifted, will remain in place until the new auxiliary lane is completed in late 2014. All exit and entrance ramps will remain open; however drivers should expect reduced shoulders. 

Nightly lane closures will occur on I-395 North between 9:30 p.m. and 5:00 a.m. for striping of the temporary alignment, to install construction signage, and place concrete barriers throughout the work area. 

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 spring 2016.

Completed:

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.
