State Route 35 (SR 35), generally known asSkyline Boulevard for most of its length, is a mostly two-lanestate highway in theU.S. state ofCalifornia. It runs along the ridge of theSanta Cruz Mountains from the high point ofState Route 17 nearLexington Reservoir inSanta Clara County toState Route 1 just south ofDaly City inSan Mateo County, where it crosses SR 1 and loops aroundLake Merced to becomeSloat Boulevard inSan Francisco. SR 35 then continues along Sloat Boulevard until it reaches its terminus when it meets SR 1 again at19th Avenue.
Because of its high elevation and location, it is one of the few places on the southern portion of theSan Francisco Peninsula from which theSan Francisco Bay and thePacific Ocean are both visible at the same time. It also provides scenic views of theSilicon Valleymetropolitan area.
It was originally designatedState Route 5 (SR 5), but was re-numbered with the creation ofInterstate 5 (I-5) as part of the1964 state highway renumbering to avert confusion.
The highway begins at the junction of Summit Road andState Route 17, atPatchen Pass. While SR 17 traverses the pass outright, SR 35 primarily is on the ridgeline. The portion of SR 35 from SR 17 to Bear Creek Road is called Summit Road. The highway then merges with Bear Creek Road for a few miles before becoming Skyline Boulevard. It bears the name Skyline Boulevard for a majority of its route along theridge of theSanta Cruz Mountains to the west ofSilicon Valley, passing by cities such asSan Jose,Saratoga, andPalo Alto. The southern portion of the road, starting at Highway 17 and ending at Black Road, is mostly a narrow and winding country road without a double-yellow line. However, the road has been upgraded to 2 lanes beginning at Black Road, and remains in this configuration until it merges with Interstate 280 north of California State Route 92. The road reaches its highest elevation nearSanborn Skyline County Park at about 3,000 ft (914 m). The road passes through the small community ofSky Londa where it intersectsState Route 84. The ridge that the road follows forms the border betweenSanta Cruz andSanta Clara counties. However, the boundary is so irregular that the road weaves in and out of the two counties.
The ridgetop portion of the route ends at the junction withState Route 92,[4] because this northern area of the Santa Cruz Mountains is a protectedwatershed owned by theSan Francisco Water Department. Highway 35 isco-routed with SR 92 for 2 miles (3 km) east, descending towardsCrystal Springs Reservoir, which it crosses on acauseway, and then joinsInterstate 280 northbound for 6 miles (10 km). However, on the southbound side, Route 35 exists as a separate road to the west of the freeway betweenBunker Hill Dr. and Route 92, as there is no connector road between 280 South and 92 West.
Route 35 departs from 280 at the southern end ofSan Bruno, running to the west of the freeway, regaining the ridgetop separatingSouth San Francisco andDaly City fromPacifica.
It crossesState Route 1 in Daly City and in San Francisco, Skyline Boulevard ends and the highway briefly continues along Sloat Boulevard until it reaches its terminus when it intersects Highway 1 again at 19th Avenue.
SR 35 is part of theCalifornia Freeway and Expressway System,[5] but is not part of theNational Highway System,[6] a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[7] SR 35 is eligible for theState Scenic Highway System;[8] however, only the portion from the Santa Cruz–Santa Clara County line to theSR 92 junction is officially designated as a scenic highway by theCalifornia Department of Transportation,[9] meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[10]
Because of its scenic views and winding roadway, Skyline Boulevard and surrounding roads see substantial recreational motoring and bicycling use. Manysports cars andmotorcycles can be found congregating near the intersections withState Route 9 andState Route 84, particularly on weekends.Mountain bikers are also commonly found at the manytrailheads along the road.
Several public open spaces border on Skyline Boulevard, includingSanborn County Park,Windy Hill, and thePurisima Open Space; both the latter are parts of theMidpeninsula Regional Open Space District. Numerous hiking trails originate from parking lots off Skyline in these open spaces.
Whenever there is snow on the road's higher elevations, many people take their families up to see and play in the snow, and therefore, many of the parking lots at regional parks are packed with cars.
For most of the route, State Route 35 offers vistas of bothSan Francisco Bay and thePacific Ocean. The route passes through or by severalMidpeninsula Regional Open Space District preserves and other parks, from south to north:
A number of streams originate near Skyline Boulevard, flowing to bothPacific Ocean and the Bay. Among the bayside streams areSan Francisquito Creek,Redwood Creek, andSan Bruno Creek.
Theoriginal road called State Route 35 was located insouthern California and ran north to south fromState Route 22 (Garden Grove Boulevard) inOrange County toU.S. 99 (Garvey Avenue), first along Los Alamitos Boulevard going north which, after enteringLos Angeles County, turns into Norwalk Boulevard. Route 35 continued west on Centralia Street and then north along Pioneer Boulevard until hitting San Antonio Drive atRosecrans Avenue. San Antonio Drive would turn back into Norwalk Boulevard and continue with that street name until turning into Old Mill Road atBeverly Boulevard. Route 35 would wind through Rose Hills and Avocado Heights as Workman Mill Road and would then turn into Puente Avenue atValley Boulevard where it would continue to its end at U.S. 99 (which was concurrent with U.S. Routes60 and70) at the border ofBaldwin Park andWest Covina.
The current State Route 35, Skyline Boulevard, was originally designated State Route 5. The number was changed in the1964 renumbering in California. On February 10, 2017, a hugewashout washed away a 220-foot stretch of SR 35 about five miles south of the junction withState Route 9. Repairs were completed and the section of road re-opened January 9, 2018.[11]
Except where prefixed with a letter,postmiles were measured on the road as it was in1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, seeCalifornia postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
