California State Route 85
state highway in Santa Clara County, California, United States
State Route 85 (SR 85) is a state highway which connects the cities of southern San Jose and Mountain View in the U.S. state of California. At a length of 24.2 miles (38.9 km), the route serves as a bypass of U.S. Route 101 (US 101) in the Santa Clara Valley area, running through the foothill cities of Los Gatos, Saratoga, Cupertino, roughly paralleling the Santa Cruz Mountains up to an interchange with Interstate 280 (I-280). The highway also intersects with SR 87, SR 17, and SR 237.
SR 85 is officially known as the West Valley Freeway along its entire length. A significant portion of the route is also signed as the Norman Y. Mineta Highway, after former San Jose Mayor, U.S. Congressman, Secretary of Commerce, and Secretary of Transportation Norman Mineta. The northernmost segment between I-280 and US 101, paralleling the Stevens Creek, also is known as the Stevens Creek Freeway.
SR 85 was built in two phases: the first, comprising the northern half, runs 5.7 miles (9.2 km) from Stevens Creek Boulevard near I-280 to its northern terminus at US 101 in Mountain View, was built in the 1960s. The second half, running 18.5 miles (29.8 km) from US 101 in southern San Jose to Stevens Creek Boulevard in Cupertino, remained unbuilt until the 1990s, and was opened in segments between 1991 and 1994. Prior to the construction of the freeway, the route was signed along Mathilda Avenue and De Anza Boulevard from US 101 near SR 237 southwards until its junction with SR 9 in Saratoga, which then served as its southern terminus until it was decommissioned the same day the freeway opened.

Why this record matters
The phrase “state highway in Santa Clara County, California, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q757970. Authority coordinates are 37.262, -121.973. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1991 and 1994.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
