 One left lane, and once you get into that left lane south of Glebe Road, the ride past Shirlington is good. Just be prepared, however, for the roadwork southbound 395 starting about a half a mile north of Hedsel Road. More resurfacing operations with various lanes blocked, and there is a brief delay as you make the approach to the Springfield interchange. And once you cross over the Beltway onto 95, you have roadwork south of 123 to just north of Dale Boulevard. Maintenance work with the left lane, central lane, mobile closures.
