Per Wiki: 210 in Pasadena was not fully opened until 1974. The last section in the San Fernando Valley to be completed was between Highway 118 in Lake View Terrace, and Lowell Avenue in La Crescenta. While this section was largely completed by 1976, the portion between Sunland Boulevard and Wheatland Avenue (traversing the Tujunga Wash) was not fully completed until 1981. From 1976 to 1980, the uncompleted section of Interstate 210 (notably near the interchange with Highway 118, near the Paxton Street exit) was rented by Columbia Pictures Television for the filming of the television series, CHiPs.
