Post 1964 Signage History
In 1963, this route was defined to run from Route 395 east of Riverside
to Route 31 south of Devore.
In 1969, Chapter 294 changed "Route 395" to "Route 15".
In 1976, Chapter 1354 changed "Route 15" to "Route 194" and "Route 31" to
"Route 15".
In 1982, Chapter 681 changed "Route 194" to "Route 215".
Pre 1964 Signage History
This routing was LRN 276, defined in 1959.The original definition of LRN 276 was as follows: "LRN 78 (US 395) east of Riverside to LRN 193 (Route 31) south of Devore.". The reference to Route 31 was, at the time, a long
offramp for future I-15 at the Devore I-15/I-215 split.
Route 81 was not defined as part of the initial state signage of
routes in 1934. It is unclear what (if any) route was signed as Route 81
between 1934 and 1964. Based on research, it looks like the number was not
in use during that time as a signed route number.
Status
It is unsigned, and no specific routing was ever determined. This was in the planning stages, but there are no local roads meeting the
definition of a traversable highway.
According to the 2013 Traversable Highways report, no local roads
adequately fit the description of a traversable highway. There are no
plans.
TEA-21 funded the reconstruction of the Route 81
(Sierra Avenue) and I-10 Interchange in Fontana. Although the legislation
noted that Sierra Avenue is Route 81, it is not signed as Route 81 and
doesn't appear to be formally part of the route.
Freeway
[SHC 253.1] Entire route; unconstructed. Added to the Freeway and
Expressway system in 1959.
Statistics

Pre-1964 Legislative Route
The route that would become LRN 81 was first defined in 1933 as the route
from "[LRN 71] to [LRN 1] N of Smith River", and was codified in 1935 into
the highway code as roughly that routing:
"[LRN 71] to [LRN 1], staying north of the Smith River"
This definition remained unchanged until the 1963 renumbering. This is
present-day Route 197 between US 101 and US 199.
Acronyms and Explanations:
