The Perth Amboy Ferry Slip, located on Arthur Kill in Perth Amboy, Middlesex County, New Jersey, United States, was once a vital ferry slip for boats in New York Harbor. It was added to the New Jersey Register of Historic Places and National Register of Historic Places in 1978. The ferry slip was restored in 1998 to its 1904 appearance. A replica of the ticket office has been constructed and is used as a small museum.HistoryPerth Amboy is located at the mouth of the Raritan River at the Raritan Bay, an arm of the Lower New York Bay. Perth Amboy served as the capital from 1686 until 1776. In 1684, it became the capital of East Jersey and remained so after the union of East and West Jersey in 1702, becoming an alternate colonial capital with Burlington until 1776. Ferry service at the site dates back to 1684. During the colonial era and for a long thereafter, Perth Amboy was an important way-station for travel between New York City and Philadelphia. The slip was later used to transport newly arrived immigrants from Ellis Island, many of whom remained in the town.
