The Story
In the 1820s Pennsylvania set out to bind its interior together with a state-built network of canals, and men like David Leech turned that ambition into ditches, locks, and towns. A Bucks County native and Allegheny College–trained engineer, Leech came to the Kiskiminetas valley in 1827 to build a lock and dam for the Pennsylvania Canal, then platted a town beside his work in 1829 and gave it his name. Leechburg grew up as a canal town, its fortunes tied to the boats, freight, and travelers moving along the waterway that Leech helped construct.
Why it matters
Leechburg is a small monument to the canal age, when state-funded 'internal improvements' opened Pennsylvania's backcountry and seeded the towns that followed the water routes west.

D. Leech & Company ⎯⎯⎯ Western Transportation Company
Leechburg, PA
In the canal age that briefly stitched Pennsylvania together, David Leech's freight-forwarding house ran goods and travelers along the state's Main Line of Public Works, the ambitious 1830s public-works system that linked Philadelphia to Pittsburgh by a patchwork of canals, inclined-plane railroads, and river navigation. Rather than hand cargo off at every break in the route, D. Leech & Company (later the Western Transportation Company) coordinated canalboats, wagons, railroads, and steamships into a single through-service — an early example of integrated logistics. From 1829 to 1853 it grew into one of the largest and most successful forwarders in the state, and the surrounding town of Leechburg still carries the family name.
Leechburg Keystone Marker
Leechburg, PA
This blue-and-gold cast-iron sign is one of Pennsylvania's Keystone Markers, a statewide series from the early twentieth century that fixed the identity and origin of towns along the roadside. Leechburg took its name from David Leech, an enterprising figure of the early republic who developed the settlement on the Kiskiminetas River in the era when the Pennsylvania Canal threaded freight and passengers through the state's interior. A canal town by birth, it later grew into a busy iron and tin manufacturing community as industry followed the water and rail routes west.
The Hyde Park Foot Bridge
Leechburg, PA
This wooden footbridge over the Kiskiminetas River carried pedestrians between Leechburg and the Hyde Park neighborhood, resting on stone piers left behind by the Pennsylvania Railroad's East Leechburg Bridge. It was engineered in 1920 by the John A. Roebling's Sons Co. of Trenton — the same storied firm whose wire-rope work made the Brooklyn Bridge possible. When the catastrophic St. Patrick's Day Flood of March 1936 swept through the Allegheny and Kiskiminetas valleys, it tore the span away, and the community rebuilt it the following year.
Allegheny County
Pittsburgh, PA
When Allegheny County was carved out of Westmoreland and Washington counties in 1788, its seat at Pittsburgh was already a generation old — laid out in 1764 at the strategic forks where the Allegheny and Monongahela join to form the Ohio, a gateway that had drawn soldiers, traders, and settlers pushing west. Incorporated as a city in 1816, Pittsburgh grew into one of the great engines of American industry, its furnaces and mills pouring out the iron and steel that earned the region its "Workshop of the World" reputation. The county's story runs straight from a frontier river junction to the smoke-and-fire heart of the nation's industrial age.
