Mercer County, New Jersey

Etymology

The county was named for Continental Army General Hugh Mercer, who died as a result of wounds received at the Battle of Princeton on January 3, 1777. Continental Army Brigadier General Hugh Mercer served in the Continental Army during the Battle of Trenton and the Battle of Princeton in 1777. A Scotsman who had fled to British North America after the failed Jacobite Rebellion, he worked closely with George Washington in the American Revolution. On January 3, 1777, Washington's army was en route to Princeton, New Jersey. While leading a vanguard of 350 soldiers, Mercer's brigade encountered two British regiments and a mounted unit. A fight broke out at an orchard grove and Mercer's horse was shot from under him. Getting to his feet, he was quickly surrounded by British troops who mistook him for George Washington and ordered him to surrender. Outnumbered, he drew his saber and began an unequal contest. He was finally beaten to the ground, bayoneted repeatedly (seven times), and left for dead. Legend has it that a beaten Mercer, with a bayonet still impaled in him, did not want to leave his men and the battle and was given a place to rest on a white oak tree's trunk, and those who remained with him stood their ground. The Mercer Oak, against which the dying general rested as his men continued to fight, appears on the county seal and stood for 250 years until it collapsed in 2000.

History

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 25–26, 1776, General George Washington led American forces across the Delaware River to attack the Hessian forces in the Battle of Trenton on the morning of December 26, also known as the First Battle of Trenton. After the battle, Washington crossed back to Pennsylvania. He crossed a third time in a surprise attack on the forces of General Charles Cornwallis at the Battle of the Assunpink Creek, on January 2, 1777, also known as the Second Battle of Trenton, and at the Battle of Princeton on January 3. The successful attacks built morale among the pro-independence colonists. Ewing Church Cemetery in Ewing is one of the oldest cemeteries in the area, having served the Ewing community for 300 years. It is home to the burial places of hundreds of veterans from The Revolutionary War to the Vietnam War.

Since 1790, Trenton has served as the state's capital, earning the county the name "the Capital County." After the Legislature relocated to Trenton from Perth Amboy in 1790, it purchased land for £250 and 5 shillings and constructed a new state house, designed by Philadelphia-based architect Jonathan Doane, beginning in 1792. The Doane building was covered in stucco, measured 150 by, and housed the Senate and Assembly chambers in opposite wings. To meet the demands of the growing state, the structure was expanded several times during the 19th century. New Jersey, along with Nevada, is the only state to have its capital be located at the border with another state, as Trenton is across the Delaware River from Pennsylvania. The official residence of the governor of New Jersey, known as Drumthwacket, is located in Princeton, and is listed on both the U.S. National Register of Historic Places and the New Jersey Register of Historic Places.

The county experienced rapid urbanization and population growth during the first half of the 20th century due to the growth of industrialization in places such as Trenton. Mercer County was the 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. A commemorative monument is erected at Grovers Mill park.

There were 27 Mercer County residents killed during the September 11 terrorist attacks in Lower Manhattan. A 10 ft long steel beam weighing one ton was given to the county by the Port Authority of New York and New Jersey in March 2011 and is now displayed at Mercer County Park.

Geography and climate

The lowest elevation is sea level, spread out along the shores of the tidal portions of the Delaware River, Crosswicks Creek and the smaller waterways within the Trenton-Hamilton Marsh in Hamilton Township and the city of Trenton.

Politics

Mercer County is a reliably Democratic county; it has gone for Republicans only three times (in 1956, 1972, 1984) since 1936. In each presidential election of the 21st century, the Democratic candidate earned at least 60% of the vote. Since the 2008 election, every municipality has voted for the Democratic candidate, and in the 2024 election, it was the 2nd most Democratic county in the state. This comes after Joe Biden won the county by 40.0% in 2020, the widest margin for anyone since 1964. As of October 1, 2021, there were a total of 265,703 registered voters in Mercer County, of whom 121,653 (45.8%) were registered as Democrats, 41,701 (15.7%) were registered as Republicans and 98,343 (37.0%) were registered as unaffiliated.

State elections

Transportation

Roads and highways

Mercer County has county routes, state routes, U.S. Routes and Interstates that all pass through. , the county had a total of 1524.30 mi of roadways, of which 1216.48 mi were maintained by the local municipality, 175.80 mi by Mercer County, 118.99 mi by the New Jersey Department of Transportation, 1.19 mi by the Delaware River Joint Toll Bridge Commission and 12.43 mi by the New Jersey Turnpike Authority.

Mercer County is served by the following major roadways:

• U.S. Route 1 (Which bisects the county)
• U.S. Route 1 Business
• Route 27 (Only in Princeton)
• Route 29
• Route 31
• Route 33
• Route 64 (A small state-maintained bridge located in West Windsor)
• Interstate 95 (New Jersey Turnpike)
• Route 129
• U.S. Route 130
• Route 133 (Only in East Windsor)
• Interstate 195
• U.S. Route 206
• Interstate 295

I-295 functions as a partial ring-road around the Trenton area, while I-195 serves as an east–west expressway from Trenton to the Jersey Shore. The New Jersey Turnpike (I-95) passes through the southeastern section of the county, and serves as a major corridor to Delaware, Washington, D.C. to the south, and New York City and New England towards the north. Two turnpike interchanges are located within Mercer County: Exit 7A in Robbinsville Township and Exit 8 in East Windsor Township.

Before 2018, Interstate 95 abruptly ended at the interchange with US 1 in Lawrence Township, and became I-295 south. Signs directed motorists to the continuation of I-95 by using I-295 to I-195 east to the New Jersey Turnpike. This was all due in part to the cancellation of the Somerset Freeway that was supposed to go from Hopewell Township in Mercer County up to Franklin Township in Somerset County.

The section of I-95 west of the US 1 interchange in Lawrence was re-numbered as part of I-295 in March 2018, six months before a direct interchange with Interstate 95 in Pennsylvania and the Pennsylvania Turnpike opened. This planned interchange indirectly prompted another project: the New Jersey Turnpike Authority extended the 'dual-dual' configuration (inner car lanes and outer truck / bus / car lanes) to Interchange 6 in Mansfield Township, Burlington County from its former end at Interchange 8A in Monroe Township, Middlesex County. This widening was completed in early November 2014.

The county roads that traverse through are County Route 518 (only in the Hopewells), 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.
