Veterans Day concert created no major traffic - or transit - problems Bruce Springsteen, Rihanna and Eminem turn the Mall into a rollicking yet respectful salute to the nations" veterans. Nov. 11, 2014 Bruce Springsteen, center, performs with Dave Grohl and the Zac Brown Band during the Concert for Valor. The much talked about Concert for Valor on the Mall turned out to have little or no impact on area roads and Metro. The event, sponsored by HBO and others, had a permit from the U.S. Park Service for as many as 800,000 people. But there appeared to be far fewer in attendance at Tuesday night's star-studded lineup, which included Bruce Springsteen, Rihanna, Eminem and others. No official crowd estimates were released Wednesday, and park officials said they don't track those figures. Two people were arrested at the event, U.S. Park Police Sgt. Lelani Woods said Wednesday. The men, ages 22 and 26, jumped over a fence blocking off the VIP area about 5:30 p.m. Officers tried to stop the men, who resisted. The two men, both D.C. residents, were charged with assaulting a police officer, Woods said. Metro ridership Tuesday didn't break any milestones. There was concern before the concert about Metro's move to suspend trains on its Blue Line and add service to the Yellow Line in anticipation of large crowds at the concert. HBO hosted a star-studded event at the National Mall in celebration of Veterans Day on Tuesday featuring Rihanna, Eminem, Carrie Underwood, Bruce Springsteen and Metallica. Tom Johnson and Ashleigh Joplin/HBO The transit agency said it had about 523,000 trips Tuesday - a 40 percent increase over the numbers from last Veterans Day. By 10:45 p.m. Tuesday, Metro said the post-concert crowds were off the rail system. To give some perspective, Metro's July 4 rider trips is typically 500,000 to 515,000. Its highest ridership day ever was for President Obama's first inauguration, with 1.1 million trips. Before Tuesday's concert, there was some crowding at some of the larger Metro stations, including Gallery Place and L'Enfant Plaza but the congestion quickly cleared. Roads throughout downtown were closed to make way for the concert. Authorities reported no major incidents. The Washington Post's Robert Thomson - also known as Dr. Gridlock - said that "overall, traffic looked very light, typical of a fall (Columbus Day/Vets Day federal holiday.)
