Originally planned in 1683 but not constructed until about 1731, this triple arch stone bridge is believed to be one of the oldest examples of its type still existing in New Jersey, and perhaps the oldest. The bridge marks the boundary between Middlesex and Somerset counties. On April 13, 1777, a force totaling 3000 British and German troops commanded by General Cornwallis attacked the Continental Army garrison at Bound Brook. Just before dawn, an advanced party of Hessian Jaegers attacked and drove in the American picket line on River Road. Reaching the stone bridge, the Hessians were unable to advance or retreat because of a murderous fire from American troops stationed in the Half Moon Redoubt.
