I have been asked to design a short span bridge (about 40 feet long) and utilize an innovative design…Because of freeboard limitations, the bridge will probably not have any beams. (SInce a short precast beam is easy to to design)

So, probably precast deck panels on precast abutments. Hopefully, I can design something that can be used in more than one location. Todays innovative bridges all seem to be site specific or one offs.
