Erie Extension Canal
Sadsbury Township, Crawford County, Pennsylvania
Marker Inscription
Remains of the canal bed may be seen beside the railroad, below the bridge. Less than 2 miles away this Shenango Line, from New Castle, united with the Conneaut Line, from Erie. The entire canal was in use 1844-1871.

The Story
Beside the later railroad, the faint bed of the Erie Extension Canal still traces where boats once floated through this corner of Crawford County. Nearby the Shenango Line running up from New Castle joined the Conneaut Line coming down from Erie, part of a waterway that tied Lake Erie to the Ohio country. In use from 1844 to 1871, the canal was eventually eclipsed by the very railroads that now run alongside its remains.
Why it matters
The surviving canal bed beside a railroad captures a turning point in American transportation, when iron rails overtook the water routes that first opened the interior.

Erie Extension Canal
Sadsbury Township, PA · est. 1948
This channel was part of the ambitious Erie Extension Canal, which in the 1840s stitched northwestern Pennsylvania into the era's booming inland-waterway network. Engineers raised Conneaut Lake nine feet above its natural level so it could feed water into the canal at its highest point, where the Shenango and Conneaut lines met. The whole system carried boats and cargo from 1844 until 1871, when railroads finally rendered it obsolete.
Erie Extension Canal
West Fallowfield Township, PA · est. 1948
To keep the Erie Extension Canal supplied with water, builders diked off part of the great Pymatuning Swamp with a three-mile bank, creating a 600-acre reservoir along the canal's western edge. The state began the work in 1838 and the Erie Canal Company finished it in 1843–44, an early exercise in the large-scale water management that canal engineering demanded. The reservoir was one link in a system that moved goods across northwestern Pennsylvania for nearly three decades.
French Creek Feeder
Union Township, PA · est. 1948
Built between 1827 and 1834 and repaired in 1841, this feeder canal drew water from French Creek and carried it to Conneaut Lake, the great reservoir that supplied the Erie Extension Canal. Feeders like this were the unseen plumbing of the canal age, keeping the main navigation channels deep enough to float loaded boats. The larger system it served linked Erie and New Castle and operated from 1844 to 1871.
French Creek Feeder
West Mead Township, PA · est. 1948
The overgrown canal bed beside the road here is part of a channel dug between 1827 and 1834 to carry water from Meadville to Conneaut Lake for the Erie Extension Canal. Two miles downstream the feeder crossed a creek on an aqueduct, a bridge of water over water that was among the most striking engineering feats of the canal age. This modest ditch was one strand in the network that briefly made northwestern Pennsylvania a highway of commerce.
