Here is the bridge I go over on my way too and from work. The middle section is designated for bike traffic, and the outer area is supposed to be for pedestrians (outside the arches on the step up sidewalk). Lets just say I've encountered ped's walking anywhere but the outer area.

Last night on my way to work the bridge was totally unlit. If not for my lights on my bike I would have ran over two (albeit lovely) females. I also passed two bike ninjas out on their cruisers who were frozen on both sides of the yellow dividing line .
