Allegheny Aqueduct, Stone aqueduct in Robeson Township, United States
Allegheny Aqueduct is a stone structure crossing Allegheny Creek in Robeson Township with five red sandstone arches. The construction spans the creek with substantial arches made from carefully fitted stone blocks arranged to support the weight of water and canal boats above.
Built in 1824 by the Schuylkill Navigation Company under Engineer Ephriam Beech, it was part of Pennsylvania's canal expansion during the height of waterway commerce. The structure enabled canal boats to navigate across Allegheny Creek when water transport was the main way to move goods across the region.
The structure reveals how 19th-century engineers shaped transportation routes and economic activity in the region. Its original purpose shows how early trade networks relied on water routes and solid engineering to move goods.
The aqueduct is located where Pennsylvania Route 724 meets Allegheny Creek, making it easy to find and access. Walking paths allow visitors to explore the structure from different angles and view informational panels that explain how it was built and operated.
Metal spikes were added in the 1870s to anchor wooden planks that protected boats passing through the structure. These small metal points remain visible on the interior liner and show how the structure was modified years after its original construction to improve safety.
