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.

X-ed Out Pre-1964 State Shield 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 Status

Unconstructed 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.

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.
