The Greenway, originally the Essex–Hudson Greenway, is a planned state park and greenway in the northeastern New Jersey counties of Essex and Hudson. It will follow an abandoned railroad right-of-way across the New Jersey Meadowlands, over the Hackensack and Passaic rivers, as well pass through densely populated neighborhoods. The nearly 9-mile (14 km) long shared-use linear park/rail trail will encompass about 135 acres (55 ha) and will average 100 feet (30 m) in width. Running between Jersey City and Montclair, it will pass through Secaucus, the Arlington neighborhood of Kearny, North Newark, Belleville, Bloomfield and Glen Ridge. Construction began in July 2025 for initial phase in Newark and Kearny is expected to open in late 2025.
