The world's longest covered bridge, at , 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.
