Bound Brook is a borough in Somerset County, in the U.S. state of New Jersey, located along the Raritan River.

[22] Bound Brook was originally incorporated as a town by an act of the New Jersey Legislature on March 24, 1869, within portions of Bridgewater Township.

[25] The brook, which was mentioned as a boundary in a Native American deed, provides the source of the borough's name.

During the American Revolutionary War, the bridge was used repeatedly by both sides including during the Battle of Bound Brook in 1777.

[30] On April 22, 1921, over 100 people were injured in Bound Brook, and one died, when a cloud of phosgene gas began spreading over the city in the early morning hours, the result of a faulty valve of a storage tank at a paint factory in town.

The intervention of four people stopped further escape of the phosgene, which had been used in concentrated form as a chemical weapon during World War I.

[49][50] As of 2024[update], the mayor of Bound Brook is Democrat Dominic Longo, whose term expires December 31, 2027.

[3][51][52][53][54][55] David Morris was appointed in January 2024 to fill the seat expiring in December 2024 that became vacant when Dominic Longo took office as mayor.

[56] In September 2022, the borough council selected David Morris from a list of three candidates nominated by the Republican municipal committee to fill the mayoral seat expiring in December 2023 that became vacant after the resignation of Robert P. Fazen, who was moving out of the borough.

[59][60][61] For the 119th United States Congress, New Jersey's 12th congressional district is represented by Bonnie Watson Coleman (D, Ewing Township).

[90] The Bound Brook School District serves students in pre-kindergarten through twelfth grade.

[104] There was an Interparochial Catholic School in the borough, Holy Family Academy (for Pre-K to grade 8) serving the local and surrounding communities with an estimated enrollment of 150 prior to closure.

[105] In 2018, Stephen Kovacs founded and thereafter owned Kaprica United Fencing Academy in Bound Brook, where he was head coach.

[106] Kovacs was accused in 2021 by detectives of allegedly sexually assaulting two teenage fencing students multiple times in 2020 and 2021; he died in Somerset County Jail in January 2022.

[113] The historic station building on the north side of the tracks is located at 350 E. Main Street and was constructed in 1913.

[116] Somerset County offers DASH, CAT, and SCOOT routes, providing service to destinations including Franklin Township, New Brunswick, Raritan, Manville and Hillsborough Township, as well as Bridgewater Commons and Raritan Valley Community College.

[117][118] Every year, the Borough of Bound Brook hosts a nationally competitive bicycle race, the Bound Brook Cycling Classic, that on the same weekend, precedes the neighboring final purse contest, as part of the three-day Tour of Somerville, held annually on Memorial Day Weekend.

The contest in Somerville, founded in 1940 by Fred “Pop” Kugler, is the oldest professionally competitive race in the United States.

[citation needed] The lower downtown area of Bound Brook has been associated with flooding of the Raritan River.

In September 1999, many structures near the commercial zone were damaged or destroyed by record Raritan floods resulting from Hurricane Floyd.

[35][119] The highest flooding level since 1800 in Bound Brook was reached during Hurricane Floyd in September 1999 – 42.13 feet (12.84 m), according to the United States Geological Survey[120][121]—nearly matched by Tropical Storm Doria in August 1971, the April 2007 nor'easter and Hurricane Irene in August 2011.

[123] During Hurricane Floyd in 1999, a fire began in Otto Williams Harley Davidson on Main Street.

On January 12, 2020, a non flood-related, seven-alarm fire set by an arsonist ripped through commercial buildings in the downtown area, causing $52 million in damages.
