Post 1964 Signage History
In 1970, Chapter 1473 defined Route 285 as “Route 70 on West Street
in Portola northwesterly to the north city limits, then to Lake Davis via
Humbug Canyon, and then easterly to Grizzly Reservoir via the south shore
of the lake.”
In 1998, AB 2132, Chapter 877, signed September 26, 1998 deleted the
routing. The route was never constructed. According to the Caltrans
photolog, the old alignment for Route 285 essentially is exactly the same
as existing West Street (in Portola) and Lake Davis Road northeast to
Grizzly Road just northeast of the Big Grizzly Creek via Humbug Canyon.
The 4.8 miles from Portola were constructed in 1972 (22' traveled way, 3'
shoulders, 6" base, and 2" asphaltic concrete). There were problems with
the right of way and drainage.
