Description 

This trestle had a troubled history, including an arson fire in 1967. One half of the trestle was washed away in the flooding following Tropical Storm Agnes in June 1972. The B&O rebuilt, this time out of steel beams. Some equipment was trapped in Georgetown for some time and really became a large part of the impetus for rebuilding the trestle. The rebuilding of 1972 was the last major rebuilding of the trestle until 2003 when the trestle was rehabilitated and reopened for pedestrian use.
