California county routes in zone J

There are 45 routes assigned to the "J" zone of the California Route Marker Program, which designates county routes in California. The "J" zone includes county highways in Alameda, Calaveras, Contra Costa, Fresno, Kern, Inyo, Mariposa, Merced, Sacramento, San Benito, San Joaquin, Stanislaus, and Tulare counties.

J1
County Route J1 (CR J1) is a county highway in San Benito and Fresno counties in the U.S. state of California. It runs from State Route 25 in Paicines to State Route 33 in Mendota. The route is known as Panoche Road, Little Panoche Road, Shields Avenue, Fairfax Avenue, and Belmont Avenue.

The route begins in Paicines in San Benito County at State Route 25. Between Paicines and Panoche Valley, CR J1 is 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 CR J1 follows Fresno County's West Shields Avenue (which is exit 379 off of Interstate 5). Shields Avenue ends at North Fairfax Avenue. CR J1 continues south 2 mi on Fairfax Avenue to West Belmont Avenue, where CR J1 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.

County Route J2 (CR J2), or I-580 Alternate, is a county highway that is made up of a series of streets and roads in Alameda and San Joaquin counties in the U.S. state of California. It runs from the Portola Avenue overpass at Interstate 580 in Livermore to State Route 4 near the community of Holt. The route is known as portions of Portola Avenue and Livermore Avenue, Tesla Road, Corral Hollow Road, and portions of Lammers Road and Tracy Boulevard.

The route follows Portola to Livermore Avenue, where CR J2 turns southward to pass through Livermore's downtown. The highway continues past the southeast edge of Livermore to become Tesla Road and rise into the Diablo Range, which separates the outer San Francisco Bay Area from the San Joaquin Valley.
