Post 1964 Signage History Post 1964 Signage History

In 1964 Toyon (one of the company towns established during the construction of Shasta Dam) disbanded and was turned over to the Job Corps.  In 1993 the communities of Central Valley, Pine Grove, Project City, and Summit City consolidated into the incorporated City of Shasta Lake.

In 2010, SB 1318, Chapter 421, 9/29/10, changed the terminus of the definition to "Route 5 near the City of Shasta Lake."

This route was first defined in 1939; it was not formally assigned a legislative route number until 1943. It was not signed before 1964.

Route 151 was not defined as part of the initial state signage of routes in 1934.

The highway was added to accommodate heavy truck traffic to Shasta Dam, and first appears as LRN 209 on the 1940 Division of Highways Map.  LRN 209 would not be formalized as a Legislative Route until 1943 Legislative Chapter 964.  Note; the 1940 Division of Highways Map shows LRN 209 ending at the site of Shasta Dam but the road continuing to the site of Kennett on the Sacramento River.

The Gribblenation Blog "California State Route 151" provides a detailed history of Shasta Dam.

It is unclear what (if any) route was signed as Route 151 between 1934 and 1964.
