Ohio Canalor Ohio and Erie Canal
was a canal constructed in the 1820s and early 1830s. It connected Akron, Summit County, with the Cuyahoga River near its mouth on Lake Erie in Cleveland, Cuyahoga County, and a few years later with the Ohio River near Portsmouth, and then connections to other canal systems in Pennsylvania and Ohio.
-The canal carried freight traffic from 1827 to 1861, when the arrival of railroads killed the market. From 1862 to 1913, the canal served as a water source to industries and towns.
