Special note:

With Iowa and Illinois DOT's recommendation of the basket-handle, true-arch twin bridge as the new I-74 Mississippi River crossing the second phase of the bridge type selection process is now complete and the I-74 Iowa-Illinois Corridor Study moves into Phase 3 of the process — preliminary bridge design.
