History of South Brunswick
South Brunswick Township became an official township on February 21, 1798. For many years in the 1700s and 1800s, it was mostly a farming area. The Straight Turnpike, now called Route 1, was built in 1804.
The township got its name from New Brunswick. New Brunswick was named after a city in Germany called Braunschweig. This German city was very important in the past. It was also linked to King George I and King George II of Great Britain.
In 1872, the size of South Brunswick was made smaller when Cranbury was created from its southern part. Later, in 1919, Plainsboro was formed. The borders of South Brunswick today are the same as they were after these changes.
During the 1900s, South Brunswick changed a lot because of new ways to travel. A trolley line started in 1900, running next to Route 1. This trolley helped people and goods move around daily. In 1951, the New Jersey Turnpike opened. It runs along the eastern side of the township. This highway helped turn the farming areas into busy industrial zones, with many warehouses.
In 1980, about 18,000 people lived in South Brunswick. By 2020, this number grew to over 47,000 residents. Even with this growth, a large part of the township's 42 square miles (109 km2) is still undeveloped. It has many wetlands, woodlands, and open spaces.
Geography and Local Areas
South Brunswick covers about 41.02 square miles (106.23 km2). Most of this is land, with a small amount of water.
Several communities are located within South Brunswick. These include Dayton, Heathcote, Kendall Park, Kingston, and Monmouth Junction. Each of these is also a census-designated place (CDP), which means the U.S. Census Bureau tracks their populations separately.
Other smaller areas within the township are Cottageville, Deans, Franklin Park, Fresh Ponds, Little Rocky Hill, Sand Hills, South Brunswick Terrace, and Ten Mile Run.
Because South Brunswick uses several different ZIP Codes, people sometimes use the names of nearby towns like Dayton or Kendall Park even when talking about areas outside those specific communities.
Community Spotlights
Dayton
Dayton was first known as The Cross Roads. Around 1750, James Whitlock built a tavern there. Early businesses included a brick maker and a large plant nursery. In 1866, the name changed to Dayton. This honored William L. Dayton, a lawyer who helped with railroad issues. He later became a U.S. Senator and was the first Republican candidate for Vice President.
Deans
Deans got its start because it was located where two important paths met: Crosswicknung Trail (Georges Road) and Lawrence Brook. Dams were built on the brook, creating Deans Pond.
Kendall Park
After World War II, more people started moving to suburban areas. Kendall Park, located off Route 27, began to be built in 1957. Route 27 was an old Native American trail and a major road for centuries.
Kingston
Kingston was a very important early community. It was located where the Lenape Assunpink Trail crossed the Millstone River. This spot was on the busy King's Road, which helped trade. Kingston had mills and taverns, making it a lively place. The Kingston Village Advisory Committee helps look after the community. Kingston is recognized as a special "Village Center" by the state of New Jersey.
Monmouth Junction
Monmouth Junction was created because three different railroad lines met there. These were parts of the Pennsylvania Railroad and the Jamesburg and Freehold Railroad.
Waterways and Natural Areas
The Lawrence Brook, a smaller river that flows into the Raritan River, runs through the middle of South Brunswick. The township also has areas that are part of the Manalapan Brook and Millstone River watersheds. These are all connected to the larger Raritan River system.
Pigeon Swamp State Park is a state park in South Brunswick. It has 1078 acres (436 ha) of undeveloped land. The Pigeon Swamp Ledger is an old document from 1780. It shows how landowners worked together to drain the Pigeon Swamp. This was allowed by a special law from New Jersey.
South Brunswick shares borders with several other towns. In Middlesex County, it borders Cranbury, East Brunswick, Monroe Township, North Brunswick, and Plainsboro. It also borders Princeton in Mercer County and Franklin Township in Somerset County.

South Brunswick can get a lot of snow in winter, sometimes up to 3 feet (91 cm). About 4 to 5 inches (10 to 13 cm) of rain falls each month, spread evenly throughout the year. Sometimes, there can be long dry periods. During winter and early spring, "nor'easters" can happen. These storms can bring blizzards or floods to the northeastern United States. Hurricanes, tropical storms, tornadoes, and earthquakes are rare.
