The Numbered Highways in San Andreas (often called Routes or Highways) is a system of inter-connecting roads and highways that criss-cross the State of San Andreas. Routes usually consist of only two lane roads with multi laned roads in some sections. The Interstate System almost always consists of multi laned freeways and are usually more traveled then the Routes. Grand Theft Auto V has the most realistic and extensive freeway system that any other game to date.
