NBISreview…why?Required by law (MAP‐21)To ensure public safety and bridge preservationNBIS sets the national standards for the proper safety inspection and evaluation of all highway bridges.FHWA ensure that all bridges are inspected accordingly.Notes:INDOT is ultimately responsible for all bridge inspections in the state; this includes ensuring compliance of NBIS regulations by LPAsReview provides a bridge inspection program assessment that potentially identify any deviation from the standards.

NBISreview…Whatisit?Risk‐based and data driven reviewPerformed annually and is based on 23 bridge metrics identified in the NBIS regulations

Each metric is assessed and determined to be:CompliantSubstantially Compliant ‐ requires action by INDOTNon‐Compliant – requires action by INDOTConditional Compliant ‐ requires action by INDOT

Some criteria evaluate sample of bridgesSome criteria evaluate entire bridge population in NBI
