Cedar Ridge High School is a defunct public high school in Old Bridge Township, in Middlesex County, in the U.S. state of New Jersey, that opened in 1968 and closed in June 1994.
The school opened in 1968 as part of an effort to address overcrowding at Madison Township High School.
[1] Old Bridge High School opened in September 1994 and was formed from the merger of Cedar Ridge High School and Madison Central High School, which were the two existing high schools in Old Bridge Township.
[3] The school's football team had a perfect 9–0 season in 1973—one of three winning seasons in 25 years—and was recognized by the New Jersey State Interscholastic Athletic Association as the Central Jersey Group IV state sectional champion in the final year in which champions were awarded by the NJSIAA (rather than based on playoffs).
