Somerset County is one of America's oldest counties, and is named after the English county of Somerset. The area was first settled in 1681, in the vicinity of Bound Brook, and the county was established by charter on May 22, 1688. Most of the early residents were Dutch. General George Washington and his troops marched through the county on several occasions and slept in many of the homes located throughout the area. Somerset County also played an important part during both World War I and World War II with weapons depots and the manufacturing of the army's woolen blankets.

For much of its history, Somerset County was primarily an agricultural county. In the late 19th century, the Somerset Hills area of Somerset County became a popular country home for wealthy industrialists. The area is still the home of wealthy pharmaceutical industrialists.[20]

In the 1960s, townships that were once exclusively agricultural were quickly transformed into suburban communities. Examples include Bridgewater Township[21] and the Watchung Hills communities of Watchung, Green Brook and Warren Township.[22][23][24] This growth was aided by the development of the county's very strong pharmaceutical and technology presence. Warren Township used to be considered "the greenest place in New Jersey."[22] More recently, there has been an influx of New York City commuters who use New Jersey Transit's Raritan Valley Line and Gladstone Branch or use Interstate 78.


Somerset County is served by a number of different routes.

Major county roads that pass through include County Route 512, County Route 514, County Route 518, County Route 523, County Route 525, County Route 527, County Route 529, County Route 531 and County Route 533.

The only two state routes that traverse through are Route 27 (only in Franklin) and Route 28.

U.S. Routes include U.S. Route 22, U.S. Route 202 and U.S. Route 206.

The two interstates that pass through are Interstate 78 and Interstate 287.

Interstate 95 was planned to run along the Somerset Freeway from its proposed southern end in Hopewell Township, Mercer County to Franklin Township at I-287 in the 1960s. However, this was cancelled in 1983.

Route 18 runs at the New Brunswick border of Somerset.

NJ Transit provides train service on the Gladstone Branch and the Raritan Valley Line.[25][26] Public bus transportation is provided by several transit agencies.[27] NJ Transit provides bus service to the Port Authority Bus Terminal in Midtown Manhattan, as well as service to major cities in New Jersey and within Somerset County.[28] Ridewise provides three SCOOT shuttles[29] as well as DASH buses and CAT buses.[30][31]


Somerset County is governed by a five-member Board of Chosen Freeholders, whose members are elected at-large to three-year terms of office on a staggered basis, with one or two seats coming up for election each year. At an annual reorganization meeting held in the beginning of January, the board selects a Director and Deputy Director from among its members.[32] As of 2013, Somerset County's Freeholders are Freeholder Director Peter S. Palmer (R, Bernardsville, term ends December 31, 2014),[33] Freeholder Deputy Director Patrick Scaglione (R, Bridgewater Township, 2015).[34] Mark Caliguire (R, Skillman in Montgomery Township, 2015),[35] Patricia L. Walsh (R, Green Brook Township, 2013),[36] and Robert Zaborowski (R, Somerset in Franklin Township, 2014),[37][38][39]

Constitutional officers elected on a countywide basis are County Clerk Brett A. Radi (R, Somerville, 2017),[40] Sheriff Frank J. Provenzano (R, Raritan, 2013)[41][42] and Surrogate Frank Bruno (R, Branchburg, 2015).[43]

The Freeholders employ a full-time County Administrator who manages the day-to-day operations of County government. The current County Administrator is Richard E. Williams.[44] The Clerk of the Board of Freeholders oversees the work of their offices. Department heads are appointed in accordance with statute and by resolution of the board. Somerset County currently has approximately 1,400 full-time and 250 part-time employees in about 40 divisions (including the Library System).[45]

The 7th and 12th Congressional Districts cover the county.[46][47] New Jersey's Seventh Congressional District is represented by Leonard Lance (R, Clinton Township).[48] New Jersey's Twelfth Congressional District is represented by Rush D. Holt, Jr. (D, Hopewell Township).[49]

The county is part of the 16th, 17th, 21st, 22nd, 23rd and 35th Districts in the New Jersey Legislature.[50]


Somerset County has been known as one of New Jersey's more conservative counties. In the 2004 presidential election, George W. Bush carried Somerset County by a 4.3% margin over John Kerry, with Kerry carrying the state by 6.7% over Bush.[51] However, in 2008, Barack Obama became the first Democratic Presidential nominee to carry the county since Lyndon Johnson in 1964.

In the 2012 presidential election, the county was carried by Barack Obama, winning 52.8% of the vote to Mitt Romney's 47.2%, a 5.6% gap that represented a 0.5% drop off for Obama from his 2008 margin of victory in the county.[53][54]
