PRESIDENTIAL GRIDLOCK EXPECTED As some point during the afternoon, expect delays on SEPTA routes near the Coast Guard station along S Delaware Av, affecting the 25 and 64, and possibly the 63, as President Bush is expected to address Coast Guard officers as part of a visit to the city. Assuming that Air Force One will be landing at Philadelphia International Airport (and, no, I don't have details about the motorcade, which is justifiably top secret), you can also expect some delays on the Airport Corridor lines as well (37, 68, 108, and 305).
