*2012 FHWA summary statistics are used for New Hampshire and Tennessee's deficient bridge totals due to significant discrepancies between FHWA summary statistics and the data in the NBI. The TN & NH county numbers reflect our analysis of the NBI and will differ slightly from the state totals in the national rankings. Click here for more info on the data.
