Local Systems

Bridge information and resources

As of May 4, 2020, Local Systems has presented offers for City bridges on this year’s candidate list with priority point ratings of 21 and above. We are still awaiting responses from some of the candidates. After receiving responses, we will determine if there is enough funding available to send out another round of offers. As a reminder, we only offer funding to candidates if remaining funds can accommodate all bridges on the candidate list within a certain range of priority point ratings. The complete candidate list for FFY 2021 will be posted when it is finalized and all offers have been made.

On an annual basis, the Iowa DOT extends federal-aid, federal-aid swap, and state funding for replacement or rehabilitation of city-owned bridges that have been classified by an engineering inspection as poor. Bridges are assigned priority points based on criteria shown on the Priority Point Worksheet. 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-aid swap, and vary according to the current federal funding methodology and availability of funds. For more information, refer to I.M. 1.100, Highway Bridge Programs for Cities and Counties.
