Union Canal
Jackson Township, Lebanon County, Pennsylvania
Marker Inscription
This canal was in use from 1828-1884. About .3 mile south at the Tulpehocken, are remains of one of the locks by which boats descended from the summit level north of Lebanon to the Schuylkill at Reading.

The Story
The Union Canal, in use from 1828 to 1884, linked the Susquehanna and Schuylkill watersheds across the rolling country of eastern Pennsylvania. Boats descended through a chain of locks from the canal's summit level near Lebanon down to the river at Reading. Remnants of one such lock still lie a short distance south along the Tulpehocken.
Why it matters
It was part of the canal-building boom that knit the young nation's interior to its ports, moving coal, iron, and grain before the railroads took over.
The story behind this marker
AI contextThe era
In the first decades after independence, the young United States faced a stubborn problem: the country was vast, its rivers ran the wrong way, and moving heavy goods overland was slow and ruinously expensive. The answer, for a brief and ambitious generation, was the canal. Beginning in the 1820s, a fever of canal-building swept the eastern states, promising to stitch the interior to the seaboard with ribbons of still water.
The rolling limestone country of eastern Pennsylvania sat squarely in the middle of that promise. Here the land rises and falls between two great watersheds, and the challenge was to carry boats up over the high ground and down the other side. The Union Canal, opened along this route in 1828, was Pennsylvania's answer to that puzzle — a working waterway threading the valleys of Lebanon County during the decades when canals, not rails, carried the nation's freight.
For more than half a century, from 1828 until 1884, this was a corridor of commerce. It belonged to an era when the pace of trade was set by the plod of a mule on a towpath and the slow filling and draining of a lock.
People & events
The everyday drama of a canal like this one happened at its locks. A lock is a water elevator: a boat enters a stone chamber, the gates close behind it, and water is let in or drained out to raise or lower the vessel to the level of the next stretch. To descend from the canal's high point — the summit level north of Lebanon — down toward the river at Reading, boats stepped down through a whole chain of these chambers, one after another.
A short distance south of here, along the Tulpehocken, the remains of one of those locks still lie in the ground. It is a quiet relic of enormous, patient labor: stone cut and fitted by hand, gates built to hold back tons of water, all tended by lockkeepers whose work was to open and close the valves as boats came through.
The men, women, and mules who worked these waters left few famous names. Their story is written instead in the worn stone and the shape of the land — the accumulated effort of thousands of ordinary trips, hauling the goods of a growing region between the summit level and the Schuylkill.
Its place in the American story
The Union Canal was one strand in a national web. Across the 1820s and 1830s, canals were how America first knit its farms and mines to its ports — most famously the Erie Canal, which opened the interior to New York in 1825 and set off the boom that reached into Pennsylvania. Coal, iron, grain, and lumber that once had no way to market could suddenly float cheaply to the cities.
What makes this route especially telling is that it links two river systems on either side of a divide. Connecting separate watersheds was the great engineering ambition of the age — proof that human ingenuity could overcome the shape of the land itself.
And yet the canal's dates tell the rest of the American story, too. By the time it closed in 1884, the railroad had won. Canals were slow and froze in winter; trains ran year-round and climbed grades a canal never could. The remains along the Tulpehocken mark not just a triumph of the canal age but the moment it passed.
If you visit
Come here expecting quiet rather than spectacle. This is a landscape you read slowly. Stand at the marker and picture the corridor of water that once ran through these valleys, and the mule-drawn boats moving at a walking pace between Lebanon's high ground and the river at Reading.
The real reward lies a short walk south, toward the Tulpehocken, where the remains of one of the old locks survive. Look for cut and fitted stone and the long, narrow shape of a chamber built to cradle a boat — the bones of a machine that has stood still for well over a century.
It makes a rewarding stop on a slow drive through Pennsylvania's canal country, especially strung together with the other Union Canal markers in the county. Wear sturdy shoes, respect any private land and posted signs, and give yourself a moment to imagine the sound of water rushing into a lock — the everyday music of a vanished age.

John A. Shulze
Marion Township, PA · est. 1951
John Andrew Shulze served as Pennsylvania's governor through the 1820s, a moment when young American states were racing to knit themselves together with roads, canals, and other public works. Under his administration the Commonwealth launched an ambitious program of internal improvements, the kind of canal-and-turnpike building that would soon reshape Pennsylvania's economy. Born in 1775 in the parsonage behind Christ Lutheran Church, in the German-settled countryside of Berks County, Shulze rose from a Lutheran pastor's household to the statehouse.
Union Canal Tunnel
North Lebanon Township, PA · est. 1947
Beneath this ridge runs what the marker calls the first canal tunnel in America, bored in 1823 as part of the ambitious Union Canal. When the full canal opened in 1827, it linked the Schuylkill and Susquehanna watersheds, carrying boats of coal and freight across the Pennsylvania interior in the golden age before railroads. The waterway ran until 1884, and its stone-lined tunnel survives as a monument to early American engineering.
Union Canal
Swatara Township, PA · est. 1950
This stretch of the Union Canal reveals the engineering ingenuity that kept 19th-century canals flowing. Water gathered behind the Big Dam in Swatara Gap traveled by a branch canal to the Water Works, where wheels and steam pumps lifted it to the summit level near Lebanon. From that high point the canal fell away in both directions, east to Reading and west to Middletown.
Union Canal
Penn Township, PA · est. 1950
Here the Union Canal ran along the north bank of the Tulpehocken, where a dam, two locks, and a mule bridge allowed boats to cross Northkill Creek. The surrounding cluster of grist mills, a lime kiln, and a tannery shows how a canal was never just a ditch of water but the spine of a small industrial community that grew up along its banks.
