[Click here for a key to the symbols used. Some county routes were constructed with federal funds. 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.]
