Delaware Canal
Tinicum Township, Bucks County, Pennsylvania
Marker Inscription
Uhlertown, known as Mexico at an earlier date, was named for Michael Uhler, boatbuilder and operator of a line of canal boats. Lock No. 18 and well-kept buildings are interesting reminders of canal days.
Erected by Pennsylvania Historical and Museum Commission
The Story
The little canal community once called Mexico took the name Uhlertown from Michael Uhler, a boatbuilder who ran his own line of boats along the Delaware Canal. Lock No. 18 and the tidy buildings clustered around it survive as reminders of the busy waterway era. In the mid-19th century, places like this hummed with the traffic of mule-drawn boats hauling coal and freight.
Why it matters
Uhlertown captures how Pennsylvania's canals spun up whole working communities, powering the industrial rise of the young republic.
The story behind this marker
AI contextThe era
By the early nineteenth century the young United States was hungry for one thing above all: a cheap way to move heavy freight. Roads were rough and slow, and the great cargo of the age — coal — was far too heavy to haul overland with any profit. The answer, borrowed from Europe and embraced across the new republic, was the canal.
Along the Delaware, a canal was cut to run the length of the valley, and where it passed, small communities sprang up to serve it. This little settlement was one of them. It had carried the curious earlier name of Mexico before it took on the identity it is remembered by today.
This was the canal era in full swing, a time when a narrow ribbon of still water and a hard-packed towpath could turn a quiet riverside spot into a working link in a regional economy. The buildings that gathered around the lock were the infrastructure of that age.
People & events
The community owes its lasting name to Michael Uhler, and his trade tells you everything about the place. He was a boatbuilder — a maker of the very craft that gave the canal its purpose — and he did not merely build boats but operated his own line of them, running freight along the waterway.
A man like Uhler sat at the center of canal-town life. Building the boats meant a yard, tools, timber, and skilled hands; running a line of them meant crews, schedules, and a steady stream of cargo moving past his door. A settlement naturally took shape around such enterprise, and in time it took his name as well.
The marker points to Lock No. 18 and the well-kept buildings around it as the surviving reminders of those days. They are the physical trace of Uhler's world — the place where boats were raised or lowered on their journey, and where the ordinary business of a nineteenth-century canal hamlet was carried on.
Its place in the American story
The canals of the early republic did more than move cargo; they built communities from scratch. Wherever a lock or a boatyard appeared, people followed — builders, boatmen, lock-tenders, and the families who supplied and fed them. Uhlertown is a small, clear example of that larger American pattern.
And what those canals carried helped power the nation's rise. The heavy freight that moved on waterways like this one — coal above all — fed the furnaces and forges of a country beginning to industrialize. The still water of a canal was, paradoxically, one of the engines of American industry.
That a whole community could grow up around a single man's boatbuilding line captures the intimate scale at which that transformation happened. The industrial age did not arrive all at once from above; it was assembled, lock by lock and town by town, by people like the boatbuilder who gave this place its name.
If you visit
This is a spot to savor slowly. Find Lock No. 18 and take in the tidy cluster of buildings around it — the marker rightly calls them reminders of canal days, and they reward an unhurried look. Picture the water alive with working boats and the towpath worn smooth by generations of passing feet and hooves.
The pleasure here is in the quiet. Where once there was the bustle of a boatyard and a busy lock, you now find a peaceful pocket of the Delaware valley, the kind of place that lets the past come close. Walk a stretch of the old towpath if you can and let the pace of canal travel settle over you.
It fits naturally into a leisurely drive along the river, one of several small communities strung like beads along the old waterway. Come without a schedule, the way the canal itself insisted, and let the landscape tell its story.

Delaware Canal
Durham Township, PA · est. 1949
Here at Lock No. 21, one of twenty-three lift locks numbered from Bristol to Easton, the Delaware Canal carried boats over Cooks Creek by aqueduct. The nine aqueducts along the route floated both water and freight across the streams feeding the Delaware River. In the canal's heyday, mule teams plodded the towpath hauling coal and goods through this quiet stretch of Bucks County.
Delaware Canal
Solebury Township, PA · est. 1949
Lock No. 12 marks one of the twenty-three lift locks that carried boats along the Delaware Canal between Bristol and Easton. Just upstream, one of the canal's nine aqueducts lifted the waterway and its traffic across a small stream draining toward the Delaware. In the mid-1800s, mule-drawn boats laden with coal passed through here in steady procession.
Pennsylvania Canal
Solebury Township, PA · est. 1949
Pennsylvania's ambitious public works program aimed to link Philadelphia, Pittsburgh, and Lake Erie by water. The Delaware Division, running Bristol to Easton, was begun in 1827 and carried anthracite and goods along the river. Operated by the state from 1831 to 1858 and by private owners until 1931, the corridor became a state park in 1940.
Pennsylvania Canal
Williams Township, PA · est. 1949
The Pennsylvania Canal was an ambitious system of state-built public works meant to bind Philadelphia, Pittsburgh, and Lake Erie together with water. Its Delaware Division, running from Bristol to Easton, was begun in 1827 and operated by the state from 1831 to 1858 before passing to private owners who ran it until 1931. In 1940 the corridor was preserved as a state park, saving a rare working relic of the internal-improvements era.
