Project Background

Historic bridges are an important part of Louisiana's culture and transportation history. The Louisiana Department of Transportation and Development (LADOTD), in coordination with the Louisiana State Historic Preservation Office (LASHPO) and the Federal Highway Administration (FHWA), commissioned a project to study historic bridges throughout the state and develop a process to manage and preserve these valued resources. Assisting the LADOTD with the project, Mead & Hunt conducted research on the history of Louisiana bridges, field surveyed certain bridges constructed through 1970, and recommended bridges eligible for listing in the National Register of Historic Places.

The publication – Crossing the Bayou: Louisiana’s Historic Bridges – highlights bridge-building in Louisiana and provides a guide to historic bridges that represent significant engineering designs, important trends and historical events. The publication is available here.


A Programmatic Agreement (PA) for Louisiana’s historic bridges outlines future program planning and procedures for managing historic bridges throughout Louisiana and will assist in streamlining the regulatory process for bridges and future preservation efforts. The PA was executed on September 21, 2015. Highlights of commitments in the PA include:

  • Statewide management plan for historic bridges
  • Individual management plans for Preservation Priority bridges
  • Historic American Engineering Record (HAER) documentation for a variety of bridge types throughout the state

Ongoing steps in the project will include implementation of these commitments and more as outlined in the approved PA, which is located here.
