 It's a busy day in the nation's capital. Road closures are already underway and will remain in effect until the fireworks are finished. The firework display is scheduled to begin at 9.09 p.m. and should last for 17 and a half minutes. You can find security checkpoints starting at 1 p.m. at Constitution Avenue and Independence Avenue west of 15th Street or by the Jefferson Memorial. And if you're making your way to fireworks tonight, Metro might make your life easier. Metro trains and buses run from 7 a.m. to midnight and are free after 5 p.m.
