• Abstract:
  Mississippi has 17,057 bridges according to the FHWA’s National Bridge Inventory. Some 22.9% were built at least 50 years ago. Simply because of age, many bridges in Mississippi are due to receive significant upgrades or replacement. Concrete is the most widespread bridge construction material and comprises 85.0% of the state’s inventory. Mississippi’s 12.8% structurally deficient share exceeds the national mark of 9.6%. Interstate 20 is projected to experience the largest growth in freight movement in the state, and already 21% of the traffic stream consists of heavy trucks. The new Panama Canal could expand commerce at Gulf Coast ports and swell the movement of freight on Mississippi highways. Robust infrastructure is of vital importance to the nation’s economy, and failure to maintain assets could have dramatically negative impacts. The present infrastructure investment level of 3.2% of GDP is below the worldwide average.
