Which was built first, Union Canal or Columbia Canal?
Union Canal (Pennsylvania) The Union Canal was a towpath canal that existed in southeastern Pennsylvania in the United States during the 19th century. First proposed in 1690 to connect Philadelphia with the Susquehanna River, it ran approximately 82 mi from Middletown on the Susquehanna below Harrisburg to Reading on the Schuylkill River.
Baillie-Grohman Canal The Baillie-Grohman Canal was a shipping canal between the headwaters of the Columbia River and the upper Kootenay River in the East Kootenay region of British Columbia at a place now known as Canal Flats, BC. The construction of the canal was required by the provincial government of British Columbia as a condition of the canal's promoter receiving substantial land concessions from the provincial government of British Columbia in the area of Creston, BC. The promoter, William Adolf Baillie-Grohman (1851–1921), was a wealthy adventurer, hunter author, and business promoter. He declared the canal to be complete in 1889. The canal was an expensive failure, being used only three times during its entire existence. In 1902, on the last use by a vessel, the sternwheeler "North Star", the sternwheeler's captain, Frank P. Armstrong deliberately blew out the canal's lower lock gates with dynamite to allow the transit of his vessel.
