The Susquehanna and Tidewater Canal between Wrightsville, Pennsylvania, and Havre de Grace, Maryland, at the head of Chesapeake Bay, provided an interstate shipping alternative to 19th-century arks, rafts, and boats plying the difficult waters of the lower Susquehanna River. Built between 1836 and 1840, it ran 43 miles (69 km) along the west bank of the river and rendered obsolete an older, shorter canal along the east bank. Of its total length, 30 miles (48 km) were in Pennsylvania and 13 miles (21 km) in Maryland. Though rivalry between Philadelphia, Pennsylvania, and Baltimore, Maryland, delayed its construction, the finished canal brought increased shipments of coal and other raw materials to both cities from Pennsylvania's interior. Competition from railroads was a large factor in the canal's decline after 1855. Canal remnants, including a lock keeper's house, have been preserved in Maryland, and locks 12 and 15 have been preserved in Pennsylvania. A copy of a detailed survey blueprint of the entire canal system including structures and property ownership details was donated (date unknown) by the Safe Harbor Water Power Corporation to Millersville University (assessed on 10/06/2016 in the MU Archives at Sp. Coll. Map 386.409748 S128 Folio). The survey consists of 67 pages, 98 x 30 cm. and is undated but the assumption is the original was created while the canal was in use.
In the 1820s, seeking raw materials from and trade with Pennsylvania's interior counties, residents of the large port city of Baltimore favored building a canal along the lower Susquehanna linking Chesapeake Bay to Pennsylvania's Main Line of Public Works at Columbia, Pennsylvania, across the river from Wrightsville. Residents of the rival port city of Philadelphia, fearing loss of trade to Baltimore, argued against the proposal. In 1829, completion of the Chesapeake and Delaware Canal across an isthmus south of Philadelphia, resolved the impasse by shortening the water link between Havre de Grace and Philadelphia to 74 miles (119 km). Since this was only 20 miles (32 km) further by water than from Havre de Grace to Baltimore, the Susquehanna and Tidewater Canal stood to benefit both cities. In 1835, the Susquehanna Canal Company of Pennsylvania joined the Tidewater Canal Company of Maryland in privately funding and building the canal. Construction began in 1836 and was finished in 1840.
