California 39 is two-part route with a gap in the middle and a closed section at the northern end (in Angeles National Forest). The longest continuously signed segment connects California 1 with California 72 along Beach Boulevard, a four- to six-lane city street that begins in Huntington Beach at California 1 and continues north via Westminster, Anaheim, and Buena Park until its end at La Habra (just after California 72). Grand plans from the mid-1960s called for construction of a freeway along California 39 (Beach Boulevard), but those plans were never realized. Today, the highway functions as a very busy urban arterial through Orange County.
Nearing the Orange-Los Angeles County Line, California 39 meets California 72 (former U.S. 101)/Whittier Boulevard in La Habra. At Whittier Boulevard, California 39 turns east until its intersection with Harbor Boulevard, where the state route currently ends. Historically, this is the point where U.S. 101 used to turn south along Harbor Boulevard toward Anaheim and Santa Ana. This is also the point where California 39 is supposed to turn left (north) onto Harbor Boulevard into the Puente Hills toward Rowland Heights in Los Angeles County. According to the legislative definition of California 39, plans call for the route to take the following route from La Habra north to West Covina: Beach Boulevard north, Whittier Boulevard east, Harbor Boulevard north, Fullerton Road north, Colima Road west, and Azusa Avenue north. The Harbor Boulevard segment from La Habra north to Rowland Heights was improved in 1992 for a wider, straighter route. However, state route shields were not erected at the time this new alignment opened. It is unclear when, if ever, the Puente Hills gap of California 39 will be signed.
In addition to the Harbor Boulevard route, access from La Habra to Hacienda Heights can also be achieved via Hacienda Road or via Los Angeles County N-8 along Colima Road and Azusa Avenue. (Colima Road was named after Tomas Sanchez de Colima, a rancher from the Mexican state of Colima who owned much of the land through which the road passes.1) California 39 resumes at Interstate 10 in West Covina along Azusa Avenue, and it continues from that point north into the mountains, terminating at Crystal Lake Recreation Area. The highway used to continue north to the Angeles Crest Highway, California 2, but it was cut off by a landslide in 1978, and it has not been reopened since. While it is possible that this abandoned segment may be reopened someday, Caltrans publicly announced in late January 2012 that it intends to abandon California 39 north of Azusa and transition it to Los Angeles County or the Forest Service for ongoing maintenance.2

|Approximately four miles south of Islip Saddle, California 39 resumes as a traversable state route. The highway will curve east a bit to meet the Crystal Lake turnoff, then proceed south into San Gabriel en route toward Azusa. The route from Crystal Lake south to San Gabriel Reservoir is a steep descent along a winding, curbing highway. California 39 does not carry through traffic due to its truncated northern terminus.

- Caltrans wants to abandon cliff-hanging Highway 39: To avoid closure of the popular San Gabriel Mountains route, Caltrans has asked the U.S. Forest Service or L.A. County to take it over, but neither wants it. by Louis Sahagun, Los Angeles Times, January 29, 2012 - Relevant quote: "In a standoff with federal forest officials, Caltrans is proposing to abandon a popular, cliff-hanging highway in the San Gabriel Mountains because it is too expensive to maintain. Caltrans' proposal to walk away from California Highway 39, enjoyed by an estimated 3 million people a year, comes as the state struggles to close a $9.2-billion budget shortfall. To avoid closure, Caltrans is trying to persuade the U.S. Forest Service or Los Angeles County to take over the roadway, which runs 27 miles from the city of Azusa nearly to the crest of the San Gabriels. Neither agency wants it."
