The route connects the [[Sonoma Valley|Sonoma]] and [[Napa Valley|Napa]] valleys with the [[Sacramento–San Joaquin River Delta]] and the [[Sierra Foothills]]. It is constructed to freeway standards from the Fulton Road/South Wright Road stoplight in [[Santa Rosa, California|Santa Rosa]], to its partial interchange with Farmers Lane (also in Santa Rosa).
==Route description== [[File:CA SR-12 Sonoma.jpg|thumb|left|SR 12 runs along Broadway in Sonoma.]] [[File:Highway 12 and Highway 113 roundabout 2.jpg|thumb|left|SR 12/SR 113 roundabout]] [[File:West Kettleman Lane in Lodi, California.jpg|thumb|left|SR 12 runs along Kettleman Lane in Lodi.]] [[File:CA State Route 12.jpg|thumb|left|SR 12 between Lodi and Jackson]]
There are six segments that are [[concurrency (road)|overlaps]] with other highways: in the Napa and Sonoma valleys with SR 121, in the southern Napa Valley with SR 29, a short overlap with I-80 at Cordelia Junction in [[Fairfield, California|Fairfield]], another short overlap with SR 99 in Lodi, and overlaps with SR 88 and SR 26 in the Sierra foothills. The highway is mainly two lane rural highway, with the exception of short segments in Santa Rosa and Fairfield/Suisun City, the overlaps with I-80 and SR 99, and segments within developed areas, such as Santa Rosa and Lodi.<ref name="Gold" /><ref name="SF">California State Automobile Association map San Francisco Bay, 1-09 edition</ref>
SR 12 begins in the west at its junction with SR 116 in [[Sebastopol, California|Sebastopol]]. After passing east through Santa Rosa on a mix of freeway, surface street, and expressway, it turns south into the Sonoma Valley, passing the [[Jack London State Historic Park]] at [[Glen Ellen, California|Glen Ellen]]. It winds through Sonoma on surface streets, where the historic [[Vallejo Estate]] and [[Mission San Francisco de Solano|Sonoma Mission]], both part of the [[Sonoma State Historic Park]], are.<ref name="Gold" /><ref name="SF" />
South of Sonoma, SR 12 turns east, joining SR 121 for nearly nine miles, then turns south briefly as it leaves SR 121 and joins the four-lane expressway SR 29 to cross the [[Napa River]]. Four miles after joining SR 29 it splits off towards the east on Jameson Canyon Road; this section is also the 1928 re-alignment of the [[Lincoln Highway]], the first road across America. After a brief merge with Interstate 80, SR 12 branches off to the east as an expressway through Fairfield and [[Suisun City, California|Suisun City]]. East of Suisun it becomes two lanes again and crosses south of [[Travis Air Force Base]], through rolling fields with numerous wind turbines. Just past Braid's Bridge is the [[Western Railway Museum]]. At [[Rio Vista, California|Rio Vista]], SR 12 crosses the [[Helen Madere Memorial Bridge]] over the [[Sacramento River]], entering the [[Sacramento – San Joaquin River Delta|California Delta]].<ref name="Gold" /><ref name="SF" />
This stretch of the river has twice been the site of much-publicized inland excursions by humpback whales, presumably veering off course while making their annual migrations along the Pacific coast. In 1985 [[Humphrey the whale]] swam about as far as the Rio Vista Bridge. In 2007 a humpback mother and calf dubbed Delta and Dawn circled for several days just upstream of the bridge, seemingly reluctant to pass under it again after having spent the previous three or four weeks upriver near [[Sacramento, California|Sacramento]].
From the Sacramento River to the junction with Interstate 5, SR 12 crosses several of the waterways of the California Delta and the low-lying fields between them. Through [[Lodi, California|Lodi]] it becomes a wide four-lane business route. After another brief merger with another freeway, this time SR 99, SR 12 heads east into the Sierra foothills (with shared segments with SR 88 and SR 26) before ending at the junction with SR 49 just north of [[San Andreas, California|San Andreas]].<ref name="Gold" /><ref name="SF" />
SR 12 is part of the [[California Freeway and Expressway System]],<ref name="cafes">{{CAFESystem}}</ref> and in Sebastopol, from US 101 to Sonoma, and from I-80 to SR 88 is part of the [[National Highway System (United States)|National Highway System]],<ref name=fhwa-nhs>{{FHWA NHS map|region=californianorth|accessdate=October 20, 2017}}</ref> a network of highways that are considered essential to the country's economy, defense, and mobility by the [[Federal Highway Administration]].<ref name=NHS-FHWA>{{FHWA NHS}}</ref> SR 12 is eligible to be included in the [[State Scenic Highway System (California)|State Scenic Highway System]];<ref name="scenic">{{CA scenic}}</ref> however, it is only designated as a scenic highway from its intersection with Danielli Avenue east of [[Santa Rosa, California|Santa Rosa]] to its junction with London Way near [[Agua Caliente, Sonoma County, California|Agua Caliente]],<ref name="caltransscenic">{{Caltrans scenic|accessdate=October 20, 2017}}</ref> meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.<ref>{{Caltrans scenic info}}</ref>

==History==
Before the 1964 renumbering, this route was signed as Sign Route 12 for most of its length. However, SR 12 was designated as Legislative Route 51 (LR 51) from SR 116 to SR 121 before the 1964 renumbering. Portions of the route from SR 29 to I-80 ran concurrently with [[California State Route 29|State Route 29]] and [[California State Route 37|State Route 37]]; this was also LR 8 and a former routing of [[U.S. Route 40 in California|US 40]]. The portion from I-80 to then-[[U.S. Route 99 in California|US 99]] was designated as LR 53 in 1919; from US 99 to SR 49, it was designated as LR 24.<ref name="cah">{{cite web|url=http://www.cahighways.org/009-016.html#012 |title=California Highways (www.cahighways.org): Routes 9 through 16 |publisher=www.cahighways.org |access-date=November 28, 2011}}</ref>
In 1976, the discontinuity resulting from the concurrency with [[California State Route 84|State Route 84]] was removed.<ref name="cah" />
In January 1996, photographer [[Charles O'Rear]] pulled off the highway east of [[Schellville, California|Schellville]] near the [[Napa County, California|Napa]]–[[Sonoma County, California|Sonoma]] county line to photograph the lush hillside by the road.
