In December 2020, the Custis Trail reopened under I-66 near Arlington’s Bon Air Park. With the underpass re-opened, the new trail roundabout is fully open and the detour is no longer needed.
The trail roundabout will enhance safety for cyclists, pedestrians, and other trail users by improving sightlines where the Custis Trail passes under I-66 and intersects with other trails. The roundabout was designed in coordination with Arlington County to improve the trail while minimizing the need to cut down nearby trees in Bon Air Park. Lighting is planned to be installed in early 2021.
