On an annual basis, the Iowa DOT extends federal and state funding for replacement or rehabilitation of city-owned bridges that have been classified by an engineering inspection as structurally deficient or functionally obsolete. Bridges are assigned priority points based on criteria shown on the Priority Point WorksheetI.M. 1.100, Federal and State Bridge Programs. Once a city requests that an eligible bridge be considered for funding, it is ranked annually until an offer of funding is made and accepted by the city or the city requests that the bridge no longer be considered for funding. The majority of funds for this program are federal and varies according to the current federal funding methodology and availability of federal funds. For more information, refer to .
This report shows each county's bridges, and the corresponding priority points according to the rating system in I.M. 1.100. Counties with questions concerning these figures should contact Niki Stinn in the Office of Local Systems at 515-239-1064 or via email at Niki.Stinn@iowadot.us.
