My objective with the series Crossing Over has been to explore the environs of the pedestrian in the ultimate freeway city.  It must have seemed like a good idea: connect two halves of a neighborhood that have been divided by a freeway with bridges accessible only to pedestrians.  Instead of having to hike or drive to the bridge designed to convey vehicular traffic down the way to get to the other side, residents would be able to walk across at conveniently spaced locations without having to deal with cars, buses or trucks.  Reality has turned out to be something else.  At times it has required considerable faith to use these bridges.  A few have been permanently closed off in response to their appropriation by gangs and other criminals who would exploit the vulnerability of innocents interested simply in getting from one side of the freeway to the other.
