which is located further east, The Susquehanna and Tidewater Canal or the Portage Canal?
Susquehanna and Tidewater Canal 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 mi along the west bank of the river and rendered obsolete an older, shorter canal along the east bank. Of its total length, 30 mi were in Pennsylvania and 13 mi 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.
Toronto Carrying-Place Trail The Toronto Carrying-Place Trail, also known as the Humber Portage and the Toronto Passage, was a major portage route in Ontario, Canada, linking Lake Ontario with Lake Simcoe and the northern Great Lakes. The name comes from the Mohawk term "toron-ten", meaning "the place where the trees grow over the water", an important landmark on Lake Simcoe through which the trail passed.
