Post 1964 Signage History Post 1964 Signage History

Post-1964 Legistlative Route Graphic As defined in 1963, Route 106 ran from Route 38 near Redlands to Route 30 near Highland.

In 1965, Chapter 1371 transferred the portion from Route 38 to Route 10 to Route 38, thus beginning the routing at Route 10.

In 1972, the entire routing for Route 106 was transferred to Route 30 by Chapter 1216.

Pre 1964 Signage History Pre 1964 Signage History

The pre-1972 routing of Route 106 was part of LRN 190, defined in 1933.

Route 106 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 106 between 1934 and 1964.

In April 1958, the designation I-106 was proposed for the route from the eastern terminus of the Santa Monica Freeway (I-10) with the Santa Ana Freeway (I-5) [i.e., the current US 101/I-5/I-10 junction) to the western terminus of the San Bernardino Freeway (I-10) with the Golden State Freeway (I-5). This designation was not approved (although AASHTO did seem to like the loop idea) infavor of distinct designations for the US 101 portion (I-105) and the I-10 portion (I-110). In 1968, both the I-105 and I-110 designations were dropped, with the segments going back to US 101 and I-10, respectively.

In 1933, Chapter 767 defined the segment from "[LRN 14] near Hercules to the Walnut Creek-Antioch Road" as a state highway. In 1935, this was codified as LRN 106 in the highway code with the following routing:

[LRN 14] near Hercules to [LRN 75]

In 1957, Chapter 36 changed LRN 14 to LRN 7, and clarified the terminus as being "north of Concord"

This is the route that runs from US 40 (now I-80) near Hercules to the Route 4/Route 24 junction N of Concord. This is signed as part of Route 4.
