 Anyone planning to use 17th, 15th, or Constitution Avenue around the White House are in luck. DC police opened those streets for the morning commute. 8th Street, however, remains closed between 17th and Vermont. Closures surrounding the Washington Convention Center will remain in place through the end of Friday, but most of the closures around Mellon Auditorium have been lifted. And for Metro riders, the Mount Vernon Square Metro Station will reopen tomorrow at 5 a.m.
