Former County Sign Route B1
[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.]
History and Signage Information
County Sign Route B1 appears to be a county adoption and signage of a portion of former
LRN 30. Based on the 1966 Gousha Map, it appears to approximate the route
of the Route 162 extension, although it is unclear if the signage covered
all of the route in Butte county, or indeed, all of LRN 30 E of Oroville.
The routing that was to be LRN 30 was defined in the 1909 First Bond
Issue as running from Oroville to Quincy. This was likely the
Oroville-Quincy Highway. In the 1919 Third Bond Issue, the route was
abandoned as a state highway and LRN 21 extended to cover the mileage to
Quincy. The original LRN 30 appears to have had the following route:
(Source: Gribblenation Blog "California State Route 162 to the Bidwell Bar Bridge (both the 1965 and 1856 variants)")
- From modern Route 162 Bridge Street east to Oroville-Quincy Highway.
- Oroville-Quincy Highway back to modern Route 162.
- Route 162 to Heritage Road.
- Heritage Road into Lake Oroville via Bidwell Canyon.
- A now sunken portion of what was LRN 30 beneath Lake Oroville to the
Middle Fork Feather River. LRN 30 would have crossed the Middle Fork
Feather River via the 1855 Bidwell's Bar Bridge.
- LRN 30 would have emerged from Lake Oroville via what is now Foreman
- Foreman Creek Road to the modern terminus of Route 162.
- From the modern terminus of Route 162 the route of LRN 30 continued
east on Oroville-Quincy Road on Plumas National Forest Route 119 to
