About the Project

I-395 HOV Ramp

This project will construct a reversible High Occupancy Vehicle/Transit ramp on I-395 at Seminary Road (Route 420). The ramp will provide improved access for HOV and transit users working at or near the Mark Center, a Department of Defense facility at Seminary Road and I-395 that holds 6,400 employees.

The ramp is scheduled to open to traffic in late Sept. 2015.

I-395 North Auxiliary Lane

The project includes 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. It will also provide easier access to the Mark Center.

The auxiliary lane opened to traffic on Feb. 4, 2015.

Overall project completion is scheduled for May 2016.

Traffic Impacts

Drivers should expect daytime lane closures during non-rush hours on the right lane of I-395 North to accommodate this work.

Noise Barrier Walls

An in-depth noise study found that noise walls would benefit multiple areas along this 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. For more information on VDOT’s sound abatement policies, use the below links to VDOT’s noise abatement resources and info on the voting procedure for proposed noise barrier walls.
