I-395 / Seminary Road Interchange

Page updated on Dec 9, 2019 at 5:09 PM


Transurban, the company that is building and managing the I-395 Express Lanes project, informed the City of Alexandria and the Virginia Department of Transportation (VDOT) in October 2018 that it would like to analyze the possibility of opening the south-facing ramp at the Seminary Road exit for high occupancy toll (HOT) paying vehicles. The south-facing ramp, opened in early 2016, was planned to remain restricted high-occupancy vehicle (HOV) and transit traffic traveling north in the morning and south in the evening, even after completion of the I-395 Express Lanes. The existing north-facing ramp (serving traffic going to and from points north, in the mornings and evenings respectively) was always planned to serve HOV, transit and HOT paying vehicles as a part of the I-395 Express Lanes project. City of Alexandria Transportation and Environmental Services (T&ES) staff is coordinating with Transurban and VDOT on an analysis (to be conducted by Transurban) of the forecasted traffic changes that could occur from the proposed change.
