Bill,

I checked the original bridge plans and the bridge was designed by Modjeski and Masters. Not sure who the on-site construction contractor was.

Who originally built it? Where can I find more information? Google has not been much help. Thanks!

I've walked this birdge. The enitre frame is rusitng and crumbling. It offers the ugliest view of Philadlephia you'll find. Just crossing it i felt seriosuly depressed and diheartend by the enormous oil refinerys and the poluted taste of the air there is sickening. Half way across a police car came by, he said "Are you okay sir? We've been getting alot calls"...people don't walk there at all unless their about to be done with the world. And being up there...I felt that energy. It's erie.
