  Greater Los Angeles is known for its expansive transportation network. Most notable is its extensive highway system. The area is a junction for numerous interstates coming from the north, east, and south and contains the three principal north–south highways in California: Interstate 5, U.S. Route 101, and California State Route 1. The area is also home to several ports, including the twin ports of Long Beach and Los Angeles, which are the two busiest in the United States, as well as Port of Hueneme. Additionally, the region is also served by the Los Angeles Metro Rail and Metrolink commuter rail systems that link neighborhoods of Los Angeles with immediate surrounding suburbs and most of the region (excluding the outer region of the Inland Empire) with Oceanside in San Diego County, respectively. Los Angeles International Airport (LAX) is the principal international airport of the region and is one of the busiest in the world. Other airports include Ontario International Airport (ONT), John Wayne Airport (SNA), Hollywood Burbank Airport (BUR), Long Beach Municipal Airport (LGB), and Palm Springs International Airport (PSP).
