Notes:

A “poor” bridge condition rating is determined by the lowest rating of the National Bridge Inventory (NBI) condition ratings for bridge deck, superstructure, substructure, or culverts. Roads are usually classified by the volumes carried and travel speeds designed for. Thus, interstate highways are considered the highest functional classification whereas local streets are considered the lowest.
