<P> 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 . </P> <P> San Diego--Tijuana's only deepwater port is both a container port and cruise ship destination . The Port of San Diego has recreation terminals and docked ships at the Maritime Museum of San Diego, which is located at the Embarcadero . The port is serviced by nine cruise lines including Carnival Cruise Line and Royal Caribbean International . A new cruise terminal was recently constructed at the Port to compensate for the increased levels of maritime tourism . </P> <P> Cargo and container terminals are located to the south of the Embarcadero where two marine cargo facilities are administered . The Port of San Diego was ranked by the United States' Bureau of Transportation Statistics as one of America's top 30 U.S. container ship ports in 2007 . The Port also serves as the primary port of entry for larger car corporations including Honda, Volkswagen, and Nissan into the United States of America . The nearby Port of Ensenada also serves as a transport point where cruise ships arrive and depart from Southern Californian, European, and Central American ports . Cargo arriving at the Port of Ensenada is also transported to the metropolitan region via the Tijuana - Ensenada Freeway . </P> <P> The Port of Punta Colonet is being planned as an alternative port to the West Coast ports of the United States and Canada; though the port is not without its negative environmental impacts. 150 miles (240 km) south of Tijuana, the port is intended to compete with the twin ports of Long Beach and Los Angeles, Once completed the port would serve as the primary dock for Asian vessels unloading shipping containers . and would have a 200 - mile (320 km) rail line to San Diego--Tijuana . </P>
