Wrightsville is a borough in York County, Pennsylvania, United States. The population was 2,310 at the 2010 census. Wrightsville borough has a police department, historic society, and a volunteer fire company. The world's longest covered bridge, at 5,960 feet (1,820m), once spanned the Susquehanna from Wrightsville to neighboring Columbia in Lancaster County. Built in 1814, it was destroyed by high water and ice in 1832. A replacement bridge was burned the night of June 28, 1863, by state militia during the Gettysburg Campaign in the American Civil War. Confederate troops under John Brown Gordon formed a bucket brigade to save the town from fire. Yet another replacement covered bridge was destroyed by a windstorm a few years later.
