'''State Route 92''' ('''SR 92''') is an east-west highway in the San Francisco Bay area between [[Half Moon Bay, California|Half Moon Bay]] near the coast (and [[California State Route 1|State Route 1]]) in the west and downtown [[Hayward, California|Hayward]] at its junction with [[California State Route 238|State Route 238]] and [[California State Route 185|State Route 185]]. It is most notable for being the route that traverses the [[San Mateo Bridge]]. It has interchanges with three freeways: [[Interstate 280 (California)|Interstate 280]] (the Junipero Serra Freeway), [[U.S. Route 101 (California)|U.S. Route 101]] (the Bayshore Freeway) in or near [[San Mateo, California|San Mateo]], and [[Interstate 880 (California)|Interstate 880]] (the [[Nimitz Freeway]]). It also connects indirectly to Interstates [[Interstate 238 (California)|238]] and [[Interstate 580 (California)|580]] by way of Hayward's Foothill Boulevard, which carries Route 238 and flows directly into Route 92.

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 (SR 92) is a state highway in the U.S. state of California, serving as a major east-west corridor in the San Francisco Bay Area. From its west end at State Route 1 in Half Moon Bay near the coast, it heads east across the San Francisco Peninsula and the San Mateo–Hayward Bridge to downtown Hayward in the East Bay at its junction with State Route 238 and State Route 185. It has interchanges with three freeways: Interstate 280 (the Junipero Serra Freeway), U.S. Route 101 (the Bayshore Freeway) in or near San Mateo, and Interstate 880 (the Nimitz Freeway) in Hayward. It also connects indirectly to Interstates 238 and 580 by way of Hayward's Foothill Boulevard, which carries Route 238 and flows directly into Route 92.

Route description

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.

SR 92 is part of the California Freeway and Expressway System,[3] and a small portion near SR 1 as well as the entire portion east of I-280 are part of the National Highway System,[4] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[5] SR 92 is eligible for the State Scenic Highway System,[6] but it is not officially designated as a scenic highway by the California Department of Transportation.[7]

History

The alignment was designated as Legislative Route Number 105 by Caltrans in 1933.[8][9]: 16–17 

The San Mateo section also was referred to as the 19th Avenue Freeway which was the street name where the freeway now exists.[10]: 22  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.[11]: III-2  On August 29, 1963, the 19th Avenue segment was completed and by 1964, the present name had been adopted; planning began for the segments in Alameda County, east of the San Mateo–Hayward Bridge, and the remainder in San Mateo County, west of Interstate 280.[12]: 30, 41 

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.[13]

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.[14]

A similar cloverleaf interchange at SR 82 (El Camino Real) was rebuilt in 2018 into a partial cloverleaf interchange.[15] Two of the loop off-ramps from SR 92 were eliminated: from westbound SR 92 to northbound El Camino Real, and from eastbound SR 92 to southbound El Camino Real. The remaining off-ramps were widened and signalized to allow left and right turns onto El Camino Real.[16]

Planning for improvements to the interchange with the Bayshore Freeway (U.S. 101) began in 2018; construction is scheduled to begin in 2024.[17] In addition, a separated bikeway will be built on Fashion Island Boulevard, which largely follows the former alignment of 19th Avenue, connecting the cities of Foster City and San Mateo. This project is scheduled to be completed by the end of 2026.[18]

Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, 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, see California 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.
