Bound Brook is a borough in Somerset County,
New Jersey, United States. As of the United States 2000 Census, the borough population was 10,155. The town was first settled in 1681. A wooden bridge over the Raritan River was erected as early as 1761 and named Queen's Bridge in 1767. Later it became a covered bridge. During the American Revolutionary War the bridge was used repeatedly by both sides including during the Battle of Bound Brook in 1777. In 1875 the wooden bridge was replaced by a steel pipe truss bridge, which was replaced by a steel girder bridge in 1984, still using the old pillars.
The Battle of Bound Brook, one of the battles in the New York and New Jersey campaign during the American Revolutionary War, occurred on April 13, 1777, and resulted in a defeat for the Continental Army, who were routed by about 4,000 troops under British command.
In September 1999, many structures in Bound Brook south of Route 28 were damaged or destroyed by floods from the Raritan River resulting from Hurricane Floyd. The flooding from this hurricane reinvigorated a long-planned effort called the Green Brook Flood Control Project that would protect Bound Brook from flooding from the Raritan River and its tributaries that comprise the western and eastern boundaries of the town
