I-480 Golden Gate Freeway

Max Rockatansky:
While I was waiting on my flight tonight I did some digging online to see what interesting California Division of Highways documents I could find.  I think stumbling upon the 1965 technical report titled (Golden Gate Freeway Interstate Route 480) is worth sharing.  Numerous design alternatives are presented along with a ton of other information.

It is somewhat comforting that not all of it would've been built on a double-decker bridge, like the Embarcadero Freeway was; in fact, this part was to be depressed in a trench and maybe go through a tunnel. However, the waterfront area and surrounding neighborhoods would've been disrupted one way or another, which came as no surprise that the whole thing ended up being cancelled. Still, it would've made a nice freeway route from the Bay Bridge to the Golden Gate Bridge.

Thanks for this. I saw this or a similar booklet once at the Alemany Antique Market ... unfortunately someone else had just purchased it. Have never seen a scan.

(However, my memory was there were larger and more extensive drawings of the tunnels underneath Telegraph and Russian hills, as if that was the preferred alternative.)

Interesting and thanks for putting it online!  The timing was wrong - if the Dept. of Highways had proposed this in the 1950s, S.F. might have said yes without a second thought.  The propaganda aspects do stand out - many photos of the traffic at rush hour, rather than street scenes at quieter times of day.  Still an interesting piece of history.

If you want to get from Oakland to Marin, why wouldn't you take the San Rafael Bridge (now I-580)?  Like paying extra tolls, spending longer in traffic, or just like orange? :)

Blew up our existing blog the last couple days.  The new version includes all the CHPW references to both the Embarcadero Freeway/Golden Gate Freeway along the Golden Gate Freeway study linked in the OP:
