State Route 39 (SR 39) is a state highway in the U.S. state of California that travels through Orange and Los Angeles counties. Its southern terminus is at Pacific Coast Highway (SR 1), in Huntington Beach. SR 39's northern terminus is at Islip Saddle on Angeles Crest Highway (SR 2) in the Angeles National Forest, but its northernmost segment (including the connection with SR 2) has been closed to public highway traffic since 1978 due to a massive mud and rockslide. Officially, the highway is broken into pieces. Caltrans has not adopted or signed the segment between La Habra and West Covina. Caltrans has also relinquished a portion of SR 39 in Buena Park from Stanton Avenue in Buena Park to Interstate 5 in 2013, as well as those segments within the cities of Azusa by 2010, Covina by 2010, and West Covina by 2013. Since 2001, a portion of SR 39 that runs through the city of Stanton has been considered for relinquishment to the city. If so, the portion that runs through the city of Anaheim will still be state controlled. Major places of interest along SR 39 are Knott's Berry Farm, an amusement park, Adventure City, another amusement park targeted for children, Huntington Beach, a local beach, a Medieval Times location, the Buena Park Auto Center, and the Westridge Golf Course in La Habra. Route description SR 39 begins at SR 1 (Pacific Coast Highway) in Huntington Beach and runs north along Beach Boulevard to Whittier Boulevard in La Habra, with the exception of the segment between the southern city limit of Buena Park and Interstate 5, which was relinquished to the city in 2013. SR 39 then turns east along Whittier Boulevard to Harbor Boulevard, taking over a former segment of SR 72, while the remaining segment SR 72 remains on Whittier Boulevard west of Beach Boulevard. The segment from the Whittier–Harbor intersection to the San Bernardino Freeway (Interstate 10) in West Covina is not officially designated by Caltrans (as indicated by an "END 39" sign at the Whittier–Harbor intersection). Under California Streets and Highways Code § 339 (d), the traversable route takes SR 39 along Harbor Boulevard north, Fullerton Road north, and then Colima Road west to Azusa Avenue in Hacienda Heights. SR 39 would then continue north on Azusa Avenue through the City of Industry to Interstate 10. Adopted SR 39 then resumes and
