[[ImageFile:California-State-Route-92-San-Mateo.jpg|thumb|left|The freeway segment of SR 92 at the US 101 interchange in San Mateo]]
Between Half Moon Bay and Interstate 280, Route 92 winds through the Coast Range as a narrow, mainly undivided two and three lane highway with a switchback turn. The east-bound uphill portion was upgraded with a long passing lane. Between Interstate 280 and Interstate 880 it is entirely a divided multilane highway, including the toll [[San Mateo-Hayward Bridge]], the longest span across the [[San Francisco Bay]]. East of Interstate 880 the route becomes a divided surface street in Hayward, locally known as '''Jackson Street'''.

State Route 92 traverses through significant habitat areas including [[wetland]], [[California oak woodland]], [[chaparral]] and [[grassland]]. In one [[serpentine soil]] location near [[Crystal Springs Reservoir]], it passes near one of the only known colonies of the [[endangered]] [[wildflower]] ''[[Pentachaeta bellidiflora]]'' and near one of the limited number of colonies of the endangered ''[[Eriophyllum latilobum]]''.

The alignment was designated as '''Legislative Route Number 105''' by Caltrans in 1933.<ref>{{cite web |url=https://www.cahighways.org/chrphas3.html |title=Chronology of California Highways, Phase III: A Significant System is Created (1933-1946) |website=California Highways |access-date=16 May 2024}}</ref><ref>{{cite magazine |url=https://libraryarchives.metro.net/DPGTL/Californiahighways/chpw_1961_mayjun.pdf |title=Bay Area Freeways |first=J.

The San Mateo section was once referred to as the '''19th Avenue Freeway''' which was the street name where the freeway now exits. Parts of the street remain. This section is also known as the '''J. Arthur Younger Freeway'''; [[J. Arthur Younger]] was a [[United States Representative]] who served during the 1950s and 60s.

===Updates===
An upgrade of the intersection with Main Street in Half Moon Bay, near the western terminus, was scheduled to be completed by fall 2008.<ref>{{cite web |url=https://www.smcta.com/projects/half-moon-bay-highway-improvements |title=Half Moon Bay Highway Improvements |publisher=San Mateo County Transportation Authority |access-date=16 May 2024}}</ref>
 
An upgrade of the intersection with Main Street in Half Moon Bay is in the late planning stage. The old [[cloverleaf interchange]] with Interstate 880 was converted into a three-level [[combination interchange]] with direct ramp replacements for two of the tight "cloverleaf" ramps, and a new wider and taller overpass to carry Route 92 over Interstate 880. The project took four years and was completed in October 2011.<ref>{{Cite webnews |url=httphttps://www.mercurynews.com/breaking2011/10/07/at-newslong-last-improved-connectors-open-at-hayward-traffic-trouble-spot/ci_19067123 |title = At long last, improved connectors open at Hayward traffic trouble spot |first=Eric |last=Kurhi |url-access=subscription |date = 7 October 2011 |newspaper=San Jose Mercury News}}</ref> A similar cloverleaf interchange at SR 82 was rebuilt in 2018 into a [[partial cloverleaf interchange]].
