Mercer County has a County Executive form of government, in which the County Executive performs executive functions and a Board of Chosen Freeholders acts in a legislative capacity. The County Executive, as of 2008, is Brian M. Hughes. Members of the seven-person Board of Chosen Freeholders are elected at-large to serve three-year staggered terms. The Board is led by a Freeholder Chair and Vice-Chair, selected on an annual basis from among its members.
The Freeholder Board acts as a formulator of policy and provides a check on the powers of the County Executive. The Board also approves all county contracts and gives advice and consent to the County Executive’s appointments of department heads, and appointments to boards and commissions. After receiving the proposed county budget from the County Executive in January of each year, it is the duty of the Freeholder Board to thoroughly review, make appropriate changes, and then vote on the budget.

Transportation[edit | edit source]
The county roads that traverse through are County Route 518 (only in Hopewell), County Route 524, County Route 526, County Route 533, County Route 535, County Route 539, County Route 546, County Route 569, County Route 571 and County Route 583.
The state routes that pass through Mercer are Route 27, Route 29, Route 31, Route 33, Route 129, and Route 133. There are three US Routes that pass through Mercer, which are: U.S. Route 1 (which bisects the county), U.S. Route 130 and U.S. Route 206.
Mercer County houses a couple of limited access roads, such as Interstate 295, Interstate 195, and Interstate 95 (which is also designated along the New Jersey Turnpike). (By chance, Mercer is the only county in the state that hosts I-95 and both its auxiliary routes.) Two turnpike interchanges are located in Mercer: Exit 7A in Robbinsville and Exit 8 in East Windsor.
Mercer County is where Interstate 95 abruptly ends at the interchange with US 1 & I-295 in Lawrence Township, and becomes I-295 south. Signs direct motorists to the continuation of I-95 by using I-295 to I-195 east to Interstate 95 / New Jersey Turnpike. This is all due in part to the cancellation of the Somerset Freeway that was supposed to go from Hopewell in Mercer County up to Franklin in Somerset County.
However, the 95 shields on the "Trenton section" are to re-numbered as part of "I-195 Extension," when a direct interchange with Interstate 95 in Pennsylvania & Interstate 276 is built (which will not be until 2017). This planned interchange has indirectly prompted the New Jersey Turnpike Authority to extend the 'dual-dual' configuration (Inner Car Lanes & Outer Truck Lanes) to Exit 6 (the Pennsylvania Extension) in Mansfield Township, Burlington County from its current end at Exit 8A (Route 32 & CR 612) in Monroe Township, Middlesex County. This widening is set to be finished by 2014.

History[edit | edit source]
Founded February 22, 1838, from portions of surrounding counties, Mercer County has a historical impact that reaches back to the pivotal battles of the American Revolutionary War. On the night of December 25, 1776, General George Washington led American forces across the Delaware River to attack the Hessian barracks in Trenton, New Jersey, who did not anticipate an attack on Christmas. Washington followed the assault with a surprise attack on General Charles Cornwallis' forces in the Battle of Princeton on the eve of January 2, 1777, eventually retaking the colony. The successful attacks built morale among the pro-independence colonists.
Mercer County also has the distinction of being the famed landing spot for a fictional Martian invasion of the United States. In 1938, in what has become one of the most famous American radio plays of all time, Orson Welles acted out his The War of the Worlds invasion. His imaginary aliens first "landed" at what is now West Windsor Township. A commemorative monument is erected at Grover's Mill park.
Sports[edit | edit source]
Mercer County is also the home of the minor league baseball team, the Trenton Thunder (Eastern League Double-A affiliate of the New York Yankees), and the minor league hockey team, the Trenton Titans, the ECHL affiliate of the NHL's Philadelphia Flyers and the AHL's Adirondack Phantoms.
