That's a heavy load to support on two ends, and it'll take a lot of steel (or rebar even if most of it will be concrete) to carry that load. So heavy, expensive footers to bear a heavy, expensive bridge. Add $50-100k to ship that monster from Minnesota, either for the ship or permitting and ******* along the interstate. To paraphrase the late senator, a hundred thousand here, a hundred thousand there, pretty soon it adds up to real money.
