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.

Here is the new NCHRP Report 584 on precast deck panels.

I switched my hosting company and hopefully I can get back to adding posts about engineering.
