First up is the 10th annual Arlington Police, Sheriff and Fire 9/11 5K race, which will get underway in Pentagon City at 6:00 p.m. on Saturday. To accommodate the race, a number of roads will be closed between 5:30 and 7:00 p.m., including parts of Army Navy Drive, S. 12th Street, Crystal Drive and the Pentagon South parking area.
Residents should also expect a ceremonial flyover of four police helicopters between 5:45 and 6:00 p.m. The race, which has been growing in scale since its inception, is sold out this year.
