With about 36,000 combined entries and exits per weekday, the Pentagon City station is the second busiest station in Northern Virginia — second only to Rosslyn — and the 10th busiest in the entire Metro system.
A study conducted by WMATA in 2010, at the request of Arlington County, concluded that a new elevator should be built on the west side of S. Hayes Street, near the Pentagon City mall, and across from an existing elevator on the east side of Hayes.
