New Jersey State Highway Routes

Route 175 is a short, 2.95 miles (4.75 km) long state highway in Mercer County, New Jersey, United States. The route runs along a former alignment of New Jersey Route 29 before the construction of the John Fitch Parkway in the 1960s. The route begins at Route 29 in the capital city of Trenton, running along Sanhican Road, River Road and West Upper Ferry Road into Ewing Township. The route serves primarily as a frontage road for Route 29. The northernmost portion of Route 175 is parallel to the Delaware and Raritan Canal until coming to an end at a merge with Route 29 in Ewing Township.

Route 175 originates as alignment of Route 29, which followed local roads after the 1927 New Jersey state highway renumbering. It remained Route 29 through the 1953 New Jersey state highway renumbering and was moved onto the John Fitch Parkway upon its completion in the 1960s. By 1969, the original alignment was designated as Route 175 and both roads have remained the same since.

Route 175 begins at an off-ramp from New Jersey Route 29 and Aberfeldy Drive in the capital city of Trenton. Inside the city limits of Trenton, the route carries one-way traffic northbound and is maintained by the City of Trenton. The route heads northward, progressing through the northern residential districts on Sanhican Drive. The highway continues, paralleling Route 29 for a distance. At an intersection with Afton Avenue, the continuation of Abernethy Drive, Route 175 changes names from Sanhican Drive to River Road. The road becomes two-way, enters Ewing Township, and is maintained by the New Jersey Department of Transportation (NJDOT). The highway continues, intersecting with Mercer County Route 643 (Lower Ferry Road) in Ewing. A short distance later, Routes 175 and 29 pass under the West Trenton Railroad Bridge along the Delaware River, passing to the south of several high-end mansions. Route 175 itself passes to the south of condominium complexes, intersecting with the access road shortly afterward.
