Pennsylvania Railroad Harsimus

The Pennsylvania Railroad Harsimus in Jersey City, NJ is a historic rail corridor and stone embankment that has been transformed into a unique green infrastructure. With lush meadows and a natural forest on top, this ecological oasis cleans air, absorbs heat, and reduces stormwater flow, providing a public space for relaxation and recreation. The Harsimus Branch and associated corridors also serve as community connectors, linking neighborhoods, historic sites, and open spaces, and forming part of the off-road East Coast Greenway, a trail network spanning from Maine to Florida.

Designed by James J. Ferris and constructed from 1901-1905, the Harsimus Branch Embankment is a remarkable physical structure that replaced an existing rail line. Its monumental qualities and sturdy construction have made it a landmark on city, state, and federal levels. As rail activities slowed, nature took over, creating a natural urban meadow and forest that thrives without human intervention. Preserving this green corridor not only sets a precedent for urban ecology but also contributes to the East Coast Greenway's goal of providing a safe and accessible trail for people of all ages and abilities.
