I kinda dig just using Saratoga Gap. Has a long history:
"
Saratoga Gap A natural saddle at the crest (2,634 feet) of the Santa Cruz Mountains at the intersection of Skyline Boulevard and Big Basin Highway. "
-- "Santa Cruz County place names: a geographical dictionary" (1986)
"State 5 drops by well-engineered grades to a junction, at 14.2 m., with La
Honda Road, on which the route goes R. ; L. here on State 5 to Saratoga Gap,
at the junction with State 9, 13.9 m. (see below).
The route goes R. on La Honda Road through dense firs and redwoods into
the deep canyon of La Honda Creek. LA HONDA (the deep), 20 m. (403 alt.,
150 pop.) (hotel, cabins, campgrounds], was founded in 1861 by John L. Sears
of Searsville. The LA HONDA STORE was built for Sears by Jim and Bob
Younger, who a little later were arrested as members of the Jesse James gang."
-- San Francisco: The Bay and Its Cities (1940)
"The route that became LRN 42 was first defined in 1913 by Chapter 398, which called for "the survey and construction of a state highway from the point known as Saratoga Gap on the line between the counties of Santa Clara and Santa Cruz, extending thence by the practicable route in a generally SW-ly direction along the ridge between the San Lorenzo and Pescadero creeks to the present boundary of the California State Redwoods Park, thence into the California State Redwoods Park in Santa Cruz County to Governor's Camp, and thence through said park to the boundary thereof at Bloom's Mill."
