Historic Bridges Inventory Summary & Results

Historic Bridge Inventory Introduction

Inventory Schedule and Public Meetings

Public Comment Form

To complete the inventory, data on bridges built through 1965 in Indiana is now being gathered and analyzed.  Under the direction of INDOT, Mead & Hunt, Inc., a consulting firm specializing in historic preservation, began work on the statewide inventory of historic bridges in June 2006. 

Completed Inventory Documents


The Indiana Historic Bridge Inventory: Methodology to Identify Select and Non-Select Bridges provides a structured methodology for identifying historic bridges that are most suitable for preservation and are excellent examples of a given type of historic bridge.  The resulting best overall preservation candidates are classified as Select Bridges.  In keeping with Stipulation II.B. of the Indiana Historic Bridge Programmatic Agreement, the methodology balances engineering and historical considerations while classifying each historic bridge as Select or Non-Select. 

The multi-step methodology relies on several data inputs to evaluate historic bridges in a way that is both transparent and replicable.  Identification of bridges that are “most suitable for preservation” is based on an engineering assessment that considers functionality, safety, feasibility, and cost-effectiveness of long-term preservation.  Identification of bridges that are “excellent examples of a given type” is based on a bridge’s historical significance compared with other bridges of the same structural type. 

The resulting methodology to identify Select and Non-Select Bridges strikes a balance between engineering criteria and historic significance in an effort to preserve the best overall candidates.
