State Route 25 (SR 25) is a state highway in the U.S. state of California between State Route 198 in Monterey County and U.S. Route 101 in Santa Clara south of Gilroy. For most of its length, SR 25 runs through the center of San Benito County.

Route description

[edit]
Looking north along SR 25 in San Benito County, California
View of SR 25

SR 25 (also known as Bolsa Road and the Airline Highway) begins at the intersection of Peach Tree Road and State Route 198 about 11 miles west of Priest Valley, in Monterey County, and is the northern extension of Peach Tree Road. It heads northwest, crossing into San Benito County and passing through the community of Bitterwater. SR 25 provides access to the Pinnacles National Park east entrance, running parallel to the San Andreas Fault.[2] Running parallel to the Gabilan Range and Diablo Range, SR 25 passes through the communities of Paicines and Tres Pinos before reaching the city of Hollister.

Upon reaching Hollister, the route turns into a four-lane undivided road, curving north and west through the east side of the city. North of Hollister, SR 25 reverts into a 2-lane road and continues northwest from Hollister, intersecting with State Route 156. From there, the route is a partially divided road until just short of a railroad crossing and eventually crossing the Pajaro River into Santa Clara County. The route then heads northwest, and at the intersection with Bloomfield Avenue, the route then curves west before its northern terminus at U.S. Route 101 south of Gilroy.[3]

SR 25 is part of the California Freeway and Expressway System,[4] and a small portion near Hollister is part of the National Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[6] SR 25 is eligible to be included in the State Scenic Highway System,[7] but it is not officially designated as a scenic highway by the California Department of Transportation.[8]

History

[edit]

The Airline Highway Association was organized in 1933-4 and was composed of representatives of Alameda, Santa Clara, San Benito, Kern and Kings Counties. Its purpose was to establish this "Airline Highway". In the Oakland Tribune article, (Tues. June 19, 1934 page 5. "NEW AIRLINE, HIGHWAY TO L.A. PLANNED") it states "the highway would follow the air line between the northern and southern part of the state as closely as possible". The use of the word Airline is confusing as we associate it with modern-day transportation. In this sense it is defined as an Americanism dating back to 1805 meaning "traveling a direct route".[9]

U.S. 29 was the southern portion of what is now SR 25. It began at the intersection of Peach Tree Road and State Route 198 about 11 miles west of Priest Valley, in Monterey County, and is the northern extension of Peach Tree Road. It headed northwest, crossed into San Benito County and passed through the community of Bitterwater. US 29 provided access to the Pinnacles National Park east entrance, running parallel to the San Andreas Fault.[2] Running parallel to the Gabilan Range and Diablo Range, US 29 passed through the community of Paicines at where it's northern terminus was at.

Existed1970–1990

U.S. 25 was the segment of Central SR 25. It began at U.S. Route 101 south of Gilroy,[3] then curves east before its intersection with Bloomfield Avenue, then was a partially divided road until just short of a railroad crossing and eventually crossing the Pajaro River into San County. North of Hollister, US 25 reverts into a 4-lane road and continues southeast into Hollister, intersecting with State Route 156. From there, the route is an undivided road, curving north and west through the east side of the city. SR 25 passes through the communities of Hollister and Tres Pinos before reaching the city of Paicines. It turned left on the intersection with US 29, then the route continued in Paicines in San Benito County at US 25. Between Paicines and Panoche Valley, US 25 was known as Panoche Road. Its north–south portion between Panoche Valley and Fresno County is called Little Panoche Road. In Fresno County, the route then intersects with Interstate 5 and terminates in Mendota at State Route 33 near State Route 180 in the Central Valley. East of Interstate 5, the alignment of US 25 follows Fresno County's West Shields Avenue (which is exit 379 off of Interstate 5). Shields Avenue ends at North Fairfax Avenue. US 25 continues south 2 miles (3.2 km) on Fairfax Avenue to West Belmont Avenue, where US 25 proceeds east on Belmont Avenue until its end at SR 33 in Mendota. Belmont Avenue continues east without the county route designation to SR 180.

Panoche Road lies within the corridor of an unbuilt Route 180 segment. No current plan exists to extend Route 180 westward from Mendota past Interstate 5 and into San Benito County.[10]

Parts of 25 east of CA-25 to Little Panoche Rd have large potholes.[11]

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.
