The thirty-nine square miles that comprise the Township originated in 1869 and was called Madison Township until 1975, when the name was changed by referendum to the Township of Old Bridge.
Initially, the Township was made up of farms and the population grew slowly. In 1880, the population was 1,662 and in 1950 it had reached only 7,365. Then the building boom started and farms gave way to developments. In 1960, the population was 22,772 and that was only the beginning. The 1980 census sited 51,406 people and even that was questioned because areas of the Township have post offices bearing the names of other communities in the area. Today, the Township population is estimated to be 60,000 and continued growth is forecasted. Of the Township's 39 square miles, approximately one third is developed.

Today there are about 8000 residents a the compact are of about 2 square miles. Old and new are blended together to form a unique community.
