until the construction of Interstate 8 in 1967. The westernmost segment of I-8 from Interstate 5 to the terminus in Ocean Beach is officially labeled the "Ocean Beach Freeway". Surfing was introduced to San Diego at Ocean Beach in 1916 when a local lifeguard borrowed a board from Duke Kahanamoku (although it's possible that George Freeth surfed there between 1907 and 1909). By 1966, the sport was sufficiently established that the World Surfing Championship was held in O.B. Nat Young won the event and was named world surfing champion. Ocean Beach was once known as the Haight-Ashbury of San Diego. The community became an attraction for hippies, who eventually became accepted by many local business establishments.

Also on Newport are restaurants, head shops, tattoo and piercing shops, coffee houses, bars, bike and surf shops, and an international youth hostel. In 1969 Hodad's opened on Newport, gaining national attention in 2007 after appearing on Diners, Drive-Ins and Dives.
