In the 19th century the Sonestown Covered Bridge survived major floods on March 1 , 1865 and June 1 , 1889 , that destroyed other bridges in the West Branch Susquehanna River valley . The latter flood was caused by the same storm system that caused the Johnstown Flood , which killed over 2,200 people . In 1885 , the Williamsport and North Branch Railroad line along Muncy Creek reached Sonestown , passing just east of the bridge . The railroad carried lumber , coal , and passengers until it closed in 1938
