Including approaches, on a new alignment, in a metropolitan area, over a major waterway... perhaps, The proposals for freight rail over (or under) New York Harbor, either at the Verrazano Narrows or under Liberty Island, definitely top $1B. Most of the new construction is meant to replace old bridges though, either those currently in use or on a formerly-abandoned alignment, so that would be much less expensive.
