Pics and size of your beams would help give us more to go on
My neighbor and I share a bridge that is engineered by county regs to handle fire trucks. He and I are responsible for the upkeep. We just recently re-decked it with 4x6 PT lumber and it is secured with carriage bolts. The span is only half of what you're describing, but the same principle could be used. We have poured concrete abutments and steel I-beams for the span.

Well what are you thinking? and whats the budget?
Basically I would look at how trailers are supported and decked. either wood or steel. Copy a HD trailer design for supports and webbing. Because thats basically what you are building....a trailer deck minus the axles and tongue.
