A festival spokeswoman says if there is a government shutdown, the parade route on Constitution Avenue will have to be shortened because part of the road is under National Park Service jurisdiction.
In the event of a government closure, the parade will run Saturday morning on Constitution from 7th Street to 14th Street to avoid crossing into Park Service territory. D.C. police would provide extra support if U.S. Park Police aren't available.
Festival organizers have been determined not to cancel the parade. Some participants are traveling from as far away as Japan. Also, 13 marching bands are scheduled to participate, including bands from Ohio, Indiana, Georgia, Alabama and New York.
The parade is scheduled to begin Saturday at 10 a.m.
