State Route 180 is a state highway in California, United States, which runs through the heart of the San Joaquin Valley from Mendota through Fresno to Kings Canyon National Park. A short piece near the eastern end, through the Grant Grove section of Kings Canyon National Park, is not state-maintained. The part east of unbuilt State Route 65 near Minkler is eligible for the State Scenic Highway System; the road east of Dunlap is the Kings Canyon Scenic Byway, a National Scenic Byway.

[edit] Route description
The western terminus of SR 180 is at State Route 33 in Mendota. An unconstructed portion of SR 180 is defined from SR 33 west across Interstate 5 to State Route 25; there are current plans to build the route to I-5 to provide better access to communities along the route.[3] Panoche Road, Little Panoche Road, Shields Avenue, Fairfax Avenue and Belmont Avenue provides a locally-maintained route along the proposed corridor from SR 25 to SR 33, and is signed as County Route J1. Until 1984, the route extended as far west as U.S. Route 101 near Gilroy, using present-day Route 25.[2]
In Fresno, SR 180 is the Sequoia-Kings Canyon Freeway, named for its destinations to the east in the Sierra Nevada - Sequoia National Park and Kings Canyon National Park. It has full interchanges with three other freeways - State Route 99, State Route 41 and State Route 168. The SR 180 freeway presently runs from Hughes-West Diagonal west of SR 99 to Clovis Avenue east of SR 168; those local streets are temporarily designated SR 180 south to the old surface alignment. The freeway is officially State Route 180S (supplemental) until the rest of it is completed, rejoining the old route on both ends.[4][5] The majority of SR 180, from SR 25 to the Grant Grove section of Kings Canyon National Park, is part of the California Freeway and Expressway System, but only the piece in Fresno has actually been constructed to freeway standards.
[edit] Major intersections and exit list
- Note: Except where prefixed with a letter, postmiles were measured in 1964, based on the alignment as it existed at that time, and do not necessarily reflect current mileage. The start and end postmiles in each county are given in the county column.
