Lassen/Plumas
County Sign Route A21
[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.]
Routing

Mooney Road from Route 147 to the Plumas county line (12.85 mi) [Lassen County].

Google Maps shows County Sign Route A21 continuing from Route 44 to Champs Flat
Road/Forest Rte 33N02, but that is unconfirmed.
History and Signage Information
This route was defined in 1963. This is likely the original portion of
LRN 183, defined in 1933.
Status
Total mileage: 22.60 mi. The Caltrans printout shows segment 2 as being
in Lassen County, but according to the Thomas Bros. atlas, it is a small
segment that cuts the corner of Plumas County (so it was likely a keypunch
error).
