Find troubled bridges in your community
Nearly 450 bridges across Michigan are rated serious or critical (49 of which are closed because they are unsafe). Engineers grade bridges' safety based on the quality of the deck, superstructure, substructure and drainage culverts. Use this map to see which bridges have serious and critical ratings and what caused them. Search by community with magnifying glass in lower left-hand corner.
