Pennypack Creek

Name

The creek draws its name from the Lenape word pënëpèkw meaning "downward-flowing water" or "deep, dead water; water without much current." Early cartographers gave various spellings for the name, including Pennishpaska, La Riviere de Pennicpacka, and Pennishpacha Kyl. In early Swedish patents it was called Pemipacka. Thomas Holme called it Dublin Creek, while in later maps it is called Pennypack and Pennepack.

Course

The Pennypack creek was first surveyed by Thomas Holme in 1687. The creek begins in two branches, one in Horsham, the other in Warminster, joining in Bryn Athyn. The creek then flows through Lower Moreland, Abington and Northeast Philadelphia.

Early use as an industrial waterway

Pennypack Creek was once the site of several mills.{{cite journal

Conversion to parkland

With the development of steam power in the Industrial Revolution, water power's influence on industry declined. As a result, many of the mills on the Pennypack closed, and by 1905 the land around it was acquired by the city for parkland. The creek now runs through Pennypack Park in Philadelphia and Lorimer Park in Montgomery County.

Segments of park trail help form the East Coast Greenway, a 3,000 mile long trail system connecting Maine to Florida.

Historic bridges

Several historic bridges cross Pennypack Creek and its tributaries.

• The Frankford Avenue Bridge, a triple-span stone-arch bridge built in 1697, carries Frankford Avenue. It is the oldest stone bridge in the United States still in use.
• The Fetters Mill Road Bridge, a Pratt through-truss bridge built in 1883, has been closed to traffic since the early 2010s. It is still open to pedestrian and bicycle traffic.
