Development/Splice length for reinforced concrete?

For anyone who's done any concrete design/detailing, I've got a question about how you handle a particular situation. I have a simple span box-girder bridge with a composite concrete deck. Traditional deck design (not empirical), 4 layers of reinforcement in the slab. The span length requires that I splice the longitudinal deck bars. Which development/splice provision is appropriate here? Since it is a simple span, the bars aren't tension bars, they're in the compression zone for the member but aren't there for strength, they're really just temperature/shrinkage bars.
