About the Project

I-395 HOV Ramp

This project constructed a reversible High Occupancy Vehicle / Transit ramp on Interstate 395 at Seminary Road (Route 420).

The ramp provides 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 reverses directions according to the same reversal schedule as the HOV lanes.

The ramp is only open to vehicles with three or more occupants and buses.

Vehicles that are not HOV-3+ are not allowed to use the ramp.

The ramp links the I-395 HOV lanes to Seminary Road on the top level of the Seminary Road interchange, where there is a new traffic signal, turn lanes, and a dedicated left-turn lane for motorists heading to the Mark Center.

The ramp opened to traffic in January 2016.

I-395 North Auxiliary Lane

The project included 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 aims to ease congestion where motorists enter and exit I-395.

It also provides easier access to the Mark Center.

The auxiliary lane opened to traffic in February. 2015.

Other elements of this project include a new Seminary Road bridge over I-395, which opened in January 2016, and a new pedestrian bridge over I-395, which opened in May 2016.

The overall project was completed in January 2017.

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.
