{"id":981,"slug":"columbia-wrightsville-bridge-remains-and-pennsylvania-canal-ruins-at-columbia-pennsylvania","story":[{"heading":null,"paragraphs":["In 1834 the Columbia-Wrightsville Bridge opened across the Susquehanna — more than a mile of covered span, the longest covered bridge in the world, carrying wagons on one side and the double tracks of the Philadelphia and Columbia Railroad through its middle. For a freedom seeker coming up from Maryland or Virginia once the Chesapeake closed down, this was the gateway: one crossing between slave country and a Lancaster County full of people paid to look the other way."]},{"heading":"Freight cars and a name","paragraphs":["Columbia's Black businessmen ran it as a machine. Stephen Smith and William Whipper, partners in the lumber trade, owned their own rail cars and shipped people out of town crated in the merchandise — by the record Whipper's agents kept, no one hidden in his cars was ever taken. Local tradition credits the valley with coining the phrase itself: slave catchers, beaten again at the Wright family's end of the bridge, complained that fugitives vanished as though on an 'underground railroad.'","On June 28, 1863, the town burned its own bridge — Pennsylvania militia and Columbia volunteers torched the span to keep Gordon's Confederate brigade from crossing at Wrightsville during the Gettysburg campaign. The stone piers still stand in the river, and eight hundred feet of Pennsylvania Canal ruins, lock included, survive beside them: the file's entry is the remains of the machine, the crossing where the metaphor and the freight literally shared a bridge."]}],"name":"Columbia-Wrightsville Bridge Remains and Pennsylvania Canal Ruins at Columbia","aliases":[],"type":"HISTORIC_SITE","type_label":"Historic Site","cats":["DARK_HISTORY","UNDERGROUND_RAILROAD_HISTORY","AFRICAN_AMERICAN_HISTORY","HISTORIC_SITE","UNDERGROUND_RAILROAD","CANAL","BRIDGE"],"groups":["dark-history","historic-sites"],"desc":"NPS-listed historic site associated with the Underground Railroad.","full_desc":"A historic site in Columbia, Pennsylvania, a National Underground Railroad Network to Freedom listing, Columbia-Wrightsville Bridge Remains and Pennsylvania Canal Ruins at Columbia is filed here for what the record attaches to it.
