Sufficiency Ratings/Load Limits on Bridges & Road Mileage Summary

Sufficiency Ratings for NBIS Bridges

Sufficiency Ratings are a rating given to a bridge between 0-100 and are used as one of several criteria for determining if a bridge is eligible for rehabilitation or replacement using Federal Bridge Funds. A sufficiency of 80 or less is a required minimum for rehabilitation funds and 50 or less for replacement funds. A map showing Appanoose County Bridges with their Sufficiency Ratings is available for viewing and downloading.

County Bridge Load Limits

As a result of these inspections, any bridge that is found to be deficient or unable to safely carry legal loads is posted with a sign that indicates what loads are allowed to cross the structure. Some bridges may also be signed as "One Lane" bridges meaning that the load limits only allow for one lane of traffic on the bridge at one time.

To view a map showing the location of all of the posted bridges in the county, open the:
