Riverfest commemorates the burning of the Columbia-Wrightsville Bridge during the Civil War. On the last Sunday in June 1863, locals prevented Confederate troops from crossing the river and moving toward Harrisburg or Philadelphia. Confederate troops were forced to turn back and just three days later, the Battle of Gettysburg erupted.
