The highway is a long scenic route that can take you from Del Perro, through North Chumash, and to Paleto Bay. A small section of the highway also passes through a tunnel that runs under part of Fort Zancudo. The highway encircles half of the map, and can be used to enter Mount Chiliad. Right off the coast of North Chumash, there is a purchasable property near the highway.
