Driving Indiana’s Economic Growth

Management and Preservation of Indiana's Historic Bridges:

A Programmatic Approach

Thanks to Mead & Hunt & FHWA-IN Division for portions of this presentation

Purpose of the Program Streamline the Section

106 review process for projects involving historic bridges

Prioritization mechanism

DefinitionsWhat is a Historic Bridge? A bridge that is listed in, or eligible for listing

in, the National Register of Historic Places.What is the “National Register of Historic

Places”?The official inventory of districts, sites, buildings, structures and objects significant in American history, architecture, archaeology and culture, which is maintained by the Secretary of the Interior…

DefinitionsWhat is Section 106 Review? Section 106 of the National Historic

Preservation Act (NHPA) of 1966 requires Federal agencies to take into account the effects of their undertakings on historic properties and afford the Advisory Council on Historic Preservation (ACHP) a reasonable opportunity to comment on these undertakings. 

o Historic Bridge Inventoryo Historic Bridge Management Process o Incentives for bridge owners to preserve

our important historic resources

Program Goals

Savings in Cost and Timeo National Register of Historic Places eligibility and

appropriate mitigation measures are known up front

o Elimination of controversy

o Historic bridge project consistency

Section 106o Monetary Costs

- $1k- $10k per bridge * 6,300 bridges!

o Complex Timelines - Can take 12-18 months

Key Stipulations of the PAo “Standards for

Rehabilitation of Bridges on Low-Volume Roads”

o Statewide bridge survey

o Identify each historic bridge as either Select or Non-select.

o Project Development Process for Select and Non-select bridges.

Overview of Key Stipulations of PAStipulation I.A. INDOT will implement the following actions or program updates within one (1) year of executing this Agreement:

Develop and include “Standards for Rehabilitation of Bridges on Low-Volume Roads” in the INDOT design manual.

“Standards for Rehabilitation of Bridges on Low-Volume Roads”

Based on best practices from:o AASHTO “Green Book”

o AASHTO Low Volume Road Guide

o FHWA Guidance

o INDOT Design Manual

“Standards for Rehabilitation of Bridges on Low-Volume Roads”

Design factors considered:o Structural Capacityo Hydraulic Improvementso Widtho Bridge Railingo Approach Guardrailo Design Speedo Approach Roadway

Economic Criteria: Select Bridge

o Cost of Rehabilitation < 80% of Cost of Replacement = Rehab warranted

o Cost of Rehabilitation ≥ 80% of Cost of Replacement = Further consultation on rehab possible

“Standards for Rehabilitation of Bridges on Low-Volume Roads”

“Standards for Rehabilitation of Bridges on Low-Volume Roads”

Economic & Other Criteria Non-Select Bridge

o Cost of Rehabilitation ≥ 40% of cost of replacement = Replacement warranted

o Two or more “other factors” apply = Replacement warranted

Overview of Key Stipulations of PAStipulation I.A

o Standards were announced March 22, 2007

o Standards became effective April 2, 2007

o Standards can be found online:

Select & Non-Select Bridges

• Select historic bridges: those most suitable for preservation that are excellent examples of a given type of historic bridge

• Non-select historic bridges: those not considered excellent examples of a given type of historic bridge and are not suitable candidates for preservation.

Programmatic Agreement Development Process

o Select Bridges Must be Preservedo Non-select Bridges may be destroyed

if other alternatives are determined neither feasible nor prudent
