Hunterdon County is a county located in the western section of the U.S. state of New Jersey. The county had a Census-estimated population of 125,488 in 2015. It is part of the New York Metropolitan Area. Its county seat is Flemington.
Hunterdon County was established on March 11, 1714, separating from Burlington County, at which time it included all of present-day Morris, Sussex and Warren counties. The rolling hills and rich soils which produce bountiful agricultural crops drew Native American tribes and then Europeans to the area.
Much of the county is hilly, with several hills rising to one thousand feet in elevation. The highest points are two areas in Lebanon Township, one on the Morris County line, both reaching approximately 1,060 feet above sea level. The first is at Smith on the Morris County line and the second is north of the area called Little Brook. This area is known as the Highlands of New Jersey. The lowest elevation is where the Mercer County line reaches the Delaware River, approximately 50 feet above sea level. The county is drained by the Musconetcong River in the north. The river flows in a southwest direction. The Lamington River drains the county in the east. The central portion of the county is drained by the South Branch of the Raritan River.
Transitioning from rural to suburban, Hunterdon County is an exurb on the western edge of New Jersey and home to commuters to New York City and Philadelphia. Rail service to the northern part of the county from Newark Penn Station is provided to High Bridge, Annandale, Lebanon and Whitehouse Station by New Jersey Transit's Raritan Valley Line. U.S. Route 22 and U.S. Route 202 and Interstate 78 pass through the county. http://co.hunterdon.nj.us/
