Route 18 is one of the Numbered Highways in San Andreas. It is an east-west urban highway that travels along the northern section of metro Los Santos. This route is signed on Interstate 1 guide signs as well as on the official GTA V print map. However, it doesn't show the exact path of the route. Presuming the route needs to begin and end at another route, and based on the control cities, it connects the Great Ocean Highway near Del Perro Beach with the Elysian Fields Freeway in East Los Santos, by West Eclipse Boulevard, Vinewood Boulevard, Mirror Park Boulevard and El Rancho Boulevard.
