The Maryland Transit Administration is warning that crowd estimates for the 360° tour’s stop at M&T Bank Stadium are now up to 80,000. Capacity for Ravens games is 71,000, and the previous record for the venue was set at 75,000 in 1999 for an HFStival crowd, the MTA said.

The MTA expects heavy traffic in the vicinity of the stadium as early as 5 p.m., two hours before opening act Florence and the Machine is scheduled to take the stage. The transit authority plans to run additional light rail and subway trains beginning at 2:35 p.m. to accommodate the crowds, with operation continuing until one hour after the concert ends.

Schedule information is available on the MTA’s Web site.
