|Walking westbound on the southern span of the Bay Bridge. We actually had to walk across two bridges. The first bridge, which you see coming up in the picture, is a smaller cantilever bridge close to the eastern shore. Later on, we'll walk across the second bridge, which is the big suspension bridge over the main shipping channel. The second bridge gives smaller ships another way to pass under the Bay Bridge. Normally, small boats can pass under the bridge anywhere, since they don't need the very deep water of the main channel or even the secondary channel. However, during the Bay Bridge Walk, all ships and boats had to pass under the second, cantilever, bridge. For whatever reason, the main channel was closed, as well as the numerous pass-throughs under the trestle spans. There were quite a few police boats and even helicopters patrolling along both sides of the bridge. If a boat tried to pass under any portion of the bridge other than the cantilever bridge, it was intercepted and redirected to the proper place. I couldn't really figure out the reason for all the diversions, but it must have been important because they devoted many people in boats and helicopters to the effort.

||Walking across the cantilever bridge near the eastern shore. As long as you kept walking, everything felt fine. But if you stopped and stood still, you could feel the bridge vibrating and shaking beneath your feet. This was a little unnerving, because I would have thought the bridge would be rock-steady with only pedestrians. It must really shake when heavy trucks go roaring across in traffic.
