California County Routes in zone J

County Route J1 is a county road in San Benito and Fresno counties. The route begins in Paicines, San Benito County, at State Route 25. Between Paicines and Panoche Valley, 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 J1 follows Fresno County's West Shields Avenue (which is Exit 379 off of Interstate 5). Shields Avenue ends at North Fairfax Avenue. J1 continues south 2 miles (3.2 km) on Fairfax Avenue to West Belmont Avenue, at which location J1 proceeds east on Belmont Avenue until its end at State Routes 33 and 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.[2]

Parts of J1 just west of I-5 are gravel rather than paved.[3]

County Route J2 or I-580 Alt. is a series of streets and roads in the California counties of Alameda and San Joaquin.

J2 begins at the Portola Avenue overcrossing of Interstate 580 in Livermore. The route follows Portola to Livermore Avenue, where 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.

At the Alameda-San Joaquin county line, J2 becomes Corral Hollow Road and enters the narrow valley of the same name. Upon approaching the San Joaquin Valley, the road turns northward, meeting Interstate 580 again and arriving at the southern subdivisions of Tracy. After passing through this city, the road intersects Interstate 205, shifts briefly onto Lammers Road, and soon turns northward onto Tracy Boulevard. Here J2 crosses the sea-level Union and Roberts Islands in the San Joaquin-Sacramento River Delta before terminating at State Route 4.

After almost 3 miles (4.8 km) the route meets Airport Way and follows it northward 21 miles (34 km) past Manteca, Lathrop, and French Camp into Stockton. J3 then follows West Lane 10 miles (16 km) out from Stockton and becomes Hutchins Street for the route's last 1 mile (1.6 km). The route reaches its northern end at State Route 12 near Lodi.
