[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.]

Valley Parkway in Escondido from Del Dios Highway to the start of
the Valley Parkway/Grand Ave couplet Crescent Road
(FAU, 1.39 mi)
Note: It appears that before the city of Escondido made Valley Parkway one-way in downtown Escondido, Crescent Road ran from its current split-point off Grand to 2nd up to Valley Parkway, permitting a traditional Valley Parkway to Crescent to Grand routing. That was since reconfigured to have Valley Parkway be one way SB/WB, Grand Ave bidirectional in the center, and 2nd one-way NB/EB. The definition has S6 along Grand; Google shows S6 along Valley, and there is no designation on 2nd.
