Beach Boulevard, Azusa Avenue, San Gabriel Canyon Road
Runs from SR-1 in Huntington Beach to SR-2 at Islip Saddle with a break from SR-72 to I-10
Route 39 is one of the more varied state highways in the Los Angeles area. It starts right at the beach at Pacific Coast Highway (SR-1), runs along Beach Boulevard for many miles through the cities of Huntington Beach, Garden Grove, Stanton, Buena Park, and La Habra only to end abruptly at the corner of Whittier Boulevard and Harbor Boulevard. State 39 reappears on the north side of the Puente Hills at the junction of I-10 and Azusa Avenue. It continues north from there, passing through the city of Azusa, onto San Gabriel Canyon Road. Now State 39 takes on a different look as it turns from a city street into a twisty mountain road. It slowly climbs along the canyon wall, using many sidehill viaducts, passing two large reservoirs and dams. After the junction with East Fork Road, State 39 climbs even faster, rising from about 2000 feet up to 6000 feet in a matter of a few miles. Just after passing the Crystal Lake turnoff the highway is blocked by a large gate. About 4.5 miles of State 39, the rest of the way to State 2, have been closed since 1978 due to a number of landslides. The roadway is passable but isn’t a full two lanes wide all the way up.
According to some sources at Caltrans District 7, there are plans to reconstruct State 39 over the closed segment to open it to the public again. Construction was slated to begin around mid-2005 but was delayed due to funding. More information will be posted here as I get it.
