The Gallia County Local School District was formed by the consolidation of four smaller school districts in 1974. They were Kyger Creek, North Gallia, Southwestern, and Hannan Trace Local School Districts. In 1983, the taxpayers of the school district approved a bond issue that paid for the construction of four new elementary schools: Bidwell-Porter, Hannan Trace, Southwestern and Vinton. It also provided for renovations at Addaville and Cheshire-Kyger. In 1991, the school district consolidated the four high schools that had represented the former local districts into one school at the former
Kyger Creek High School near Cheshire. The high school was renamed River Valley High School. The old Hannan Trace High School, located north of Crown City, was reopened and renamed South Gallia High School in 1996. ==See also==
