About the Project

I-395 HOV Ramp

This project is constructing 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 will reverse directions according to the same reversal schedule as the HOV lanes. The ramp will only be 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 will link the I-395 HOV lanes to Seminary Road on the top level of the Seminary Road interchange, where there will be a new traffic signal, turn lanes, and a dedicated left-turn lane for motorists heading to the Mark Center.

The ramp is scheduled to open to traffic in January 2016.

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 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 is slated to open in February 2016. Overall project completion is scheduled in the spring of 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.
