Roselle Park is a compact borough in eastern Union County bordered by Roselle, Union Township, Kenilworth, Cranford, and Elizabeth. The community developed around railroad lines and retains a traditional center near the NJ Transit station on the Raritan Valley Line. Westfield Avenue, Chestnut Street, and nearby Route 28 connect local neighborhoods with Elizabeth, Cranford, Newark, and other regional destinations. Roselle Park contains older single-family homes, multifamily buildings, schools, parks, houses of worship, neighborhood shops, and light industrial properties. Its small land area creates a close relationship between residential streets and commercial corridors. The borough grew rapidly during the late nineteenth and early twentieth centuries as rail access encouraged suburban and industrial development. Today, the station and downtown remain central to local identity. Roselle Park's location provides convenient access to the Garden State Parkway, Newark Liberty International Airport, and major employment centers while preserving the scale of a traditional Union County borough.
