Succasunna is an unincorporated community and census-designated place (CDP) located within Roxbury Township, in Morris County, in the U.S. state of New Jersey,[7] serving as its downtown and population center, having a population of 9,152 people as of the 2010 United States Census.[8]
The name of Succasunna comes from the Lenni-Lenape Native American word for "land of black stones", most likely due to the rich iron-ore deposits in the area.[9] The community was established circa 1740.
The Morris Canal was an important transportation link in the iron industry around Succasunna, carrying coal to iron-ore producing areas all over northern New Jersey. The canal was abandoned in 1924 and largely dismantled.
Succasunna was the site of the world's first electronic switching public telephone exchange. The Western Electric model 1ESS system was cut over for service on the New Jersey Bell 584 central office on May 30, 1965. A commemorative plaque on the wall of the central office building notes this historic event.[10] Instead of electro-mechanical relays, the 1ESS was the first commercial computerized electronic switching system. This innovation allowed for features of modern telephone service, like call forwarding, call waiting, and three-way calling.[11]
U.S. Route 46 and Route 10 pass through the area. The Morristown and Erie Railway runs rail freight service through the area 2-5 times per week on its High Bridge Branch.
