County Route 577 (New Jersey) is a county highway in New Jersey connecting suburban communities in Union County and Middlesex County. The route serves as a local arterial between Plainfield, North Plainfield, and Westfield, providing links to regional roads and transit hubs near Newark Liberty International Airport, New Jersey Turnpike, and Garden State Parkway. It functions as a commuter corridor for access to New York City, Jersey City, Elizabeth, and downtown Newark via connecting highways and mass transit.

Route description

CR 577 begins near Plainfield on local streets close to landmarks such as Plainfield High School, Rahway River Parkway, Middlesex County College, and commuter nodes serving New Jersey Transit trains on the Raritan Valley Line. The highway proceeds north through commercial districts adjacent to Stuart Country Day School of the Sacred Heart and crosses municipal boundaries into North Plainfield, passing institutions like Somerset County Vocational and Technical High School and parks associated with the Rahway River. Along its course CR 577 intersects arterial routes that provide access to Interstate 78, U.S. Route 22, and state routes leading toward Union County Courthouse and the Roselle Park business corridor.

Continuing, CR 577 runs near residential neighborhoods with proximity to cultural sites such as Fanwood Presbyterian Church, Kenilworth Veterans Memorial, and recreational spaces linked to the Rahway River County Park. The northern segment approaches Westfield, crossing rail corridors used by NJ Transit. Terminus connections provide movements toward Scotch Plains, Cranford, and regional centers including Plainfield Township and Somerville through nearby county and state routes. The roadway's pavement, sidewalks, and signalized intersections are coordinated with county planning agencies and local municipal public works departments.

History

The alignment that became CR 577 evolved from early 20th-century county roads linking colonial settlements such as Plainfield and Westfield and was influenced by transportation developments tied to Erie Railroad, Central Railroad of New Jersey, and later New Jersey Transit rail patterns. During the 1920s and 1930s, road improvements paralleled regional growth spurred by industrial employers in Elizabeth and residential expansion serving commuters to New York City. Postwar suburbanization accelerated upgrades in the 1950s and 1960s with coordination among Union County Board of Chosen Freeholders and county engineers, reflecting traffic shifts caused by completion of New Jersey Turnpike and Garden State Parkway expansions.

Later decades saw intersection redesigns influenced by federal programs administered through United States Department of Transportation and state-level planning by New Jersey Department of Transportation. Community planning initiatives tied to agencies like North Jersey Transportation Planning Authority and civic groups in Westfield, Plainfield, and North Plainfield shaped corridor safety and streetscape projects. Historic preservation interests, including local societies in Plainfield Historical Society and Westfield Historical Society, played roles when roadway work encountered historic properties.

Major intersections

The route connects with several significant corridors and municipal streets, facilitating regional mobility: - Southern terminus near Plainfield municipal streets and county routes serving Somerset County, proximate to New Jersey Transit stations on the Raritan Valley Line. - Interchange and intersections providing access toward Interstate 78, and links to U.S. Route 22 serving Union Township and Springfield. - Crossings that interface with county and state routes leading to Newark Liberty International Airport access corridors and connections toward Elizabeth and Jersey City. - Northern terminus at street network in Westfield connecting to collectors feeding Scotch Plains and Cranford municipal centers.

Transportation and traffic

CR 577 supports commuter flows to New York City and regional employment centers including Newark and Jersey City, with modal connections to New Jersey Transit bus lines and rail services. Traffic volumes reflect peak hour commuting patterns coordinated in regional plans by the North Jersey Transportation Planning Authority and monitored by county engineering divisions. Safety initiatives have addressed pedestrian crossings near Plainfield High School and transit stops linked to bus routes serving Kean University and community colleges. Multimodal planning has considered bicycle accommodations and links to trail networks adjacent to the Rahway River Parkway and county park systems.

Future plans and improvements

Planned improvements have been proposed through county capital programs and coordination with New Jersey Department of Transportation to address congestion, drainage, and multimodal access. Projects under study by the Union County Division of Engineering and regional planners include signal modernization, ADA-compliant sidewalk upgrades near Westfield Memorial Library and Plainfield Public Library, and intersection geometry changes to improve bus operations connecting to New Jersey Transit corridors. Funding discussions have involved federal programs overseen by the Federal Highway Administration and state grant initiatives administered through New Jersey Economic Development Authority and county officials to align with local land use plans and historic preservation considerations advocated by local historical societies.
