Simple Precast Bridge

We are designing a simple two span precast bridge. The pile caps will be cast in place concrete and the deck units will be precast concrete deck units (mostly 5' x 20' units) with a composite topping pour. I can not figure out how to get such a simple bridge to work in LEAP concrete, is this too simply for the program? We really need to design the rebar for the caps, deck units, and overall deck.
