About the Project

Arlington Ridge Road was included in the 2004 Arterial Transportation Management Study. The study suggested several recommendations to improve safety in this corridor for all modes of transportation. View the study’s proposed concept designs.

The two intersections covered by this project have experienced a high number of collisions. The goal of this project is to improve safety for all modes and create predictable vehicle movements at Lynn Street and the on/off ramps to I-395.

The County continues to discuss safety improvements with the Virginia Department of Transportation for the intersection of Arlington Ridge and I-395 due to federal regulations on interstate access.
