History of District 55
Prior to 1997, District 56 was comprised of the greater metropolitan areas of Houston, Austin, and San Antonio, as well as the Coastal and Rio Grande Valley areas, and the Texas Hill Country west of Austin and San Antonio. District 55 was formed when District 56 was split in 1997. District 56 remained as the District for the Greater Houston Area, and District 55 included all the other areas. In 2010, the area north of Georgetown that includes Killeen and Temple was transferred to District 55 from District 25.
