San Diego has a major network of roads, predominantly free Highways with several toll roads, and Interstates. Interstate 5 runs south from the Canadian-border city of Vancouver and terminates at the San Ysidro International border where it becomes Federal Highway 1. Another major freeway is Interstate 8 that runs west from the Arizona Sun Corridor at Casa Grande, Arizona and terminates at Ocean Beach in San Diego. The roadway system in Tijuana is very low end compared to the quality of streets in the United States. The majority of the roads are in desperate need of repair with many newly constructed off ramps being set up in an impractical method often requiring sharp and hard turns. When it comes to long distance travel through Baja California, many people use the toll roads that are well maintained and are at a standard comparable to that of U.S. roads.
