Now our attention turns to the larger San Francisco Bay area; the portion pretty much between Gilroy to the south; San Rafael to the north, and Oakland and the East Bay. Just like San Francisco, many routes were planned for this area. As with Southern California, the initial plans for freeways in this area was quite ambituous. And, as with Southern California, many of the routes that were planned never became freeways. Some exist only on paper, and some are still just everyday highways, without any control of access.

Figure 2-1 shows the 1963 plans for the San Francisco Bay Area. Figure 2-2 shows a map of the planned freeways for the area; I have annotated this to add present-day route numbers, if known. Note: To understand Figure 2-1, the subsequent renumbers must be understood:

In Part 1, we explored the routes in the city proper. Let's now look at some of the planned freeways that didn't make it. Route are referenced by their present-day route number, if one exists.

Other routes made it and were constructed:

Something closer to the present-day routings are better illustrated in this excerpt from the 1986 state highway map (Figure 2-3). Note the routes shown in open-circles, which designate routes that were never adopted. The open-dashed-lines are routes that were still planned for construction.

Note that since 1986, some routes have changed even further. In particular, Route 480 in downtown San Francisco is gone, and I-880 has had significant rerouting in Oakland.
