Louisiana Historic Bridge Inventory

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.

The project is culminating in a Programmatic Agreement for Louisiana’s historic bridges that will assist with streamlining the regulatory process for bridges and future preservation efforts.

11/7/14 - A PowerPoint presentation highlighting some past and upcoming historic bridge rehabilitation projects is now posted to the project website. The name of the presentation is Accomplishments in Historic Bridge Preservation Nov 2014. An exciting outcome of the current project and the Programmatic Agreement (PA) currently under development is guidance for future preservation and rehabilitation of the state’s historic bridges. The PA will build upon previous efforts and help the Louisiana Department of Transportation and Development (LADOTD) continue to preserve historic bridges across the state. As a reminder, any comments the public wishes to share with the project team regarding the draft PA are due by November 14, 2014.

A recording of the May 29th presentation in Baton Rouge that highlighted the results of which historic bridges have the best potential for future preservation is now available at the bottom of the project webpage. The presentation title is “Recommendations for Preservation Priority Bridges.” The FHWA, SHPO, LADOTD, and consulting parties continue to consult on the Programmatic Agreement (PA) for Louisiana’s historic bridges. The PA is expected to be finalized in September and will outline future program planning and procedures for managing historic bridges throughout the state.
