I think the local jurisdictions did a lousy job of describing bike restrictions. At one point I read in the Washington Post that all of the bridges would be closed to pedestrian and bike traffic. That would be insane. More recent maps and pronouncements indicate that the pedestrian/bike lanes will be open but many people may have been scared off. WABA is providing bike valet parking by the Jefferson Memorial so one would presume people would be allowed to cross the bridge 200 yards away.
