Lambertville is located on the Delaware River in the southwestern portion of Hunterdon County. During the 18th century, the City was named after various operators of ferries across the river to Pennsylvania, ultimately becoming known as Coryell's Ferry, after Emanuel Coryell who owned the Ferry. Coryell's Ferry was the western terminus of the New Jersey portion of the York Road (which is now known as U.S. Highway 202) connecting New York City and Philadelphia. The City was named Lambertville in 1814 when the post office was established, in honor of John Lambert, a local resident, who had served as United States Senator and Acting Governor of New Jersey.
