Phillipsburg sits on the Delaware River directly across from Easton, Pennsylvania, and takes its name from William Phillips, an early settler. A bridge has linked the two places since October 14, 1806, when a covered wooden span designed by Timothy Palmer opened at Northampton Street. The village grew quickly after the Morris Canal opened in 1831 with its western end here: in 1832 the first canal boat left the Greens Bridge area for Jersey City and returned, and canal water was soon powering grist and saw mills along Lopatcong Creek near South Main Street. The canal stayed in use until it was abandoned in 1924, after which much of the old mill pond area was filled in.
Railroads made Phillipsburg a junction. The Central Railroad of New Jersey opened to the town on July 2, 1852, the Lehigh Valley connected across the river in 1853, and at its peak five major railroads met here, with roundhouses, turntables and a shared Phillipsburg Union Station that opened in 1914. Phillipsburg was incorporated as a town on March 8, 1861, separating from Phillipsburg Township, which is now Lopatcong.
Industry followed the rails. The Ingersoll-Sergeant drill works opened in 1903, and as Ingersoll Rand it became the town's largest employer until the plant closed in 2000. The former factory site is now one of the town's redevelopment areas, along with the riverfront and a commerce park, and large warehouses have been built in recent years. Railroad heritage groups have restored Union Station's first floor and are rebuilding the Phillipsburg Union (PU) Tower, a former CNJ switch tower, under work since 2007.
Phillipsburg is a compact, fully built-out town on hills rising from the Delaware, and its older sections mix houses, shops and small industrial buildings on the same blocks. The downtown, which the town describes as a waterfront shopping district, centers on Union Square near the bridges, with South Main Street (Route 122) running south along the river and Lopatcong Creek. Neighborhood names in use include Delaware Park, Lopatcong Heights, Warren Heights, Andover Furnace and Shirmers, and smaller commercial clusters sit at places such as Center and Roseberry Streets.
Housing is a mix of single-family homes on neighborhood streets and apartment buildings, with multifamily housing concentrated west of Roseberry Street and in scattered complexes. Steep slopes and ridges limit building in parts of town. Route 22 is the highway commercial corridor, and the town's planning documents point to redevelopment at the Ingersoll Rand site, the riverfront and the Howard Street area, and to a downtown facade improvement program.
Parks are spread through the neighborhoods. Walters Park has the town pool, a half-mile walking track, ballfields and tennis courts; Green Street Park and Delaware Heights Park have fields, courts and playgrounds; and Delaware River Park has a walking track, a skate park and a dog park. Shappell Park downtown is used for concerts and small events. Public schools are run by the Phillipsburg School District.
Three bridges run by the Delaware River Joint Toll Bridge Commission connect Phillipsburg to Easton: the Route 22 toll bridge; the Northampton Street Bridge, known locally as the Free Bridge, which has sidewalks, a three-ton weight limit and a 15 mph speed limit; and the Interstate 78 toll bridge. I-78 crosses the edge of town without an exit, so drivers use the interchange in neighboring Pohatcong. U.S. Route 22 and Route 122 run through town.
There is no passenger rail station in Phillipsburg. NJ Transit has studied extending the Raritan Valley Line west to Phillipsburg, and the town's 2024 master plan reexamination still lists that extension as a goal, but no service exists as of 2026. Local buses on NJ Transit routes 890 and 891 link Phillipsburg with Pohatcong and Easton. Trans-Bridge Lines runs commuter and intercity buses to New York from a park-and-ride in Clinton, Hunterdon County.
Lehigh Valley International Airport near Allentown is roughly 16 miles away, and Newark Liberty International Airport about 59 miles. The town has a planned bikeway network, and the Morris Canal Greenway and riverfront trail plans aim to connect parks along the canal route and the Delaware.
Railroad history is the main draw. Delaware River Railroad Excursions, run by a nonprofit railroad, leave from Market Street and follow the river; for 2026 the River Train toward Riegelsville, a weekend Warren County Winery Train and a mine-themed train run from early May to the start of November, with seasonal pumpkin and holiday trains. The Phillipsburg Railroad Historians museum displays railroad memorabilia, cabooses and locomotives and operates a miniature railroad, the Centerville and Southwestern. Phillipsburg Union Station, owned by the Friends of the NJ Transportation Heritage Center, has a small transportation museum and a photo display.
The NJ Railroad Festival, held each September since 2022, links Shappell Park, Union Station, the PU Tower and the excursion railroad, with music, vendors and train rides; its 2025 edition was the fourth. Shappell Park also hosts a summer concert series and movies in the park.
Along South Main Street, historical markers note the site of canal Lock 10 West, with 120-foot stone walls and a nine-foot lift, and the early mills that drew power from Lopatcong Creek. Walking across the Free Bridge leads into Easton, and Walters Park, Delaware River Park and the riverfront offer space for walking and outdoor recreation.
