Which highway runs through both Round Rock, Texas, and Saint Paul, Minnesota?
La Frontera (Round Rock, Texas) La Frontera is Round Rock's largest master-planned, multi-use commercial business-retail-housing center and is located at the northwest corner of SH 45 Toll Road and Interstate 35 in Round Rock, Texas within Williamson County, Texas. La Frontera is also located immediately across Interstate 35 from the Dell international headquarters. The name "La Frontera" means “the border” or “frontier” in Spanish, hence the name of the project which sits at the exact border of the two counties (Travis and Williamson) and two communities (Round Rock and Austin). Because of the project's high profile, the entire area around this intersection over the years has loosely become known also as "La Frontera."
