Harrison is a compact Hudson County town on the east bank of the Passaic River, directly across from Newark. The community has transformed from a major industrial center into a growing residential and mixed-use district, particularly around the Harrison PATH station and riverfront. PATH trains provide direct connections to Newark, Jersey City, and Manhattan, while Interstate 280 and nearby Routes 1 and 9 connect the town to the regional highway network. Sports Illustrated Stadium is a prominent entertainment destination near the waterfront. Older residential streets and neighborhood businesses remain in the western part of town, while former factory land has been redeveloped with apartment buildings, offices, public spaces, and new streets. Harrison borders Kearny to the north and east, and bridges across the Passaic River connect it with Newark. Its small land area, transit access, and continuing redevelopment have made Harrison one of the most rapidly changing communities along the lower Passaic River.
