Post 1964 Signage History
In 1965, Chapter 1372 defined this route as “Route 80
southwest of Roseville to Route 65 north of Roseville” It was a
planned western bypass for Roseville.
The EIR for the Roseville Bypass provides some information as to why
Route 256 was never constructed, and was eventually deleted: Route 256, a
once adopted route for a west-side bypass of Roseville was rescinded by
the California Transportation Commission because of cost and difficulty of
crossing the Southern Pacific Switchyard. The route adoption was rescinded
(Source: Route 65 Roseville Bypass Final EIR)
This routing was deleted in 1994 by AB 3132, Chapter 1220.
Originally to have been freeway; later deleted from SHC 253.1.
