These routes are indicated as FAP (Federal Aid Primary), FAU (Federal Aid Urban), or FAS (Federal Aid Secondary). If no funding source is shown, no federal funds were used. Note that while some segments seem to have the same attributes, they may differ in the county-local road number assigned to the segment, or in the Caltrans Map Sheet number.]

History and Signage Information

County Sign Route G19 had its start in Godfrey Road, which existed as early as 1919, as it was shown on the United States Geological Survey map of Bradley from that time. The road descended to the San Antonio River via Bee Rock Canyon and Branch Ranch. The road emerged from what is now Vista Lane and crossed the San Antonio River via ford located east of the modern highway bridge near Pleyto Well. Much of the roadway north of the river is the same as modern County Sign Route G19 to Jolon Road (County Sign Route J18). During 1921, Monterey County constructed a single-lane four span Pratt Truss at the San Antonio River on Godfrey Road. The structure was 292 feet long and was the only bridge over the river for several years. During 1956, the Monterey County Water Resource Agency completed Nacimiento Dam on the namesake river in northern San Luis Obispo County. In 1965, the agency would complete San Antonio Dam. Concurrent to the construction of both dams, Godfrey Road was relocated out of Bee Rock Canyon, and a new alignment was constructed through Sulphur Canyon to Interlake Road in San Luis Obispo County to provide better connectivity with the two reservoirs.

In 1971, Godfrey Road was designated as County Sign Route G19

By 1976, Godfrey Road used Sulphur Canyon to reach Interlake Road. Godfrey Road was later renamed "Nacimiento Lake Drive." During June 2020, the Monterey County Board of Supervisors approved replacing the 1921 San Antonio River Bridge. The structure was replaced with a new bridge during 2023. The southern approach to the 1921 span was preserved and a historic plaque was installed. .
