The Westplex is part of St. Charles County that used to be called "The Golden Triangle". The "triangle" was formed by I-70 to the north, Missouri Route 94 to the southeast, and I-64 to the southwest. Since almost all of the growth in St. Charles County was within this triangle it was dubbed the "Golden" area of St. Charles county, hence, Golden Triangle. Today the Westplex is made up of [[St. Charles, Missouri|St. Charles]], [[St. Peters, Missouri|St. Peters]], [[Weldon Spring, Missouri|Weldon Spring]], [[Cottleville, Missouri|Cottleville]], [[Dardenne Prairie, Missouri|Dardenne Prairie]], [[O'Fallon, Missouri|O'Fallon]], [[Lake St. Louis, Missouri|Lake St. Louis]], and [[Wentzville, Missouri|Wentzville]].
