Riverside High School opened in the fall of 1999 as a result of the consolidation of DuPont High School and East Bank High School. Students from both of those former high school districts, Cedar Grove and Montgomery areas attend the school. Beginning in the fall of 2019 Riverside will incorporate students from the Fayette County School: Valley High School. This move will make Riverside High School the first inter-county high school in the state of West Virginia.
