Initiated in 2007 with a study population of 8000

483 bridges are considered historic and eligible or listed on the National Register

111 Bridges are National Register-listed

139 Covered bridges identified in the update

The results of the 2010 Ohio Historic Bridge Inventory Update and Evaluation were accepted by FHWA, OSHPO and ODOT on April 28, 2010

The 2010 Update determined that 7517 pre-1962 bridges do not meet NR eligibility criteria› Exempt from Section 106 consultation

Coordination with the Ohio State Historic Preservation Office is not required according to ODOT’s programmatic agreement.

Historic status of a bridge does not prohibit its replacement by local forces or as part of a federal undertaking › We just need to follow the Environmental

Process The 2010 Update study allowed us the

opportunity to investigate previously excluded types

Reinforced concrete T-beams, slabs, rigid frames, concrete girders

Cement Bridge Road in Wayne Township Tuscarawas County The oldest complete T-beam in the state. Built in 1908

Reinforced Concrete Slab 1909Considered earliest example in the state. Located TR 80in Seneca County over Royer Ditch

Steel Rigid Frame 1937McMillan St. in CincinnatiNot commonly used before 1950. Early, aesthetically detailed example.

Concrete Thru Girder 1910Richland County Chew RoadOver Nofolk & Southern RRBuilt by Pennsylvania RREarly example during period of Experimentation for this type

109 bridges are considered highly significant. ODOT has completed

Management Plans for 13 structures so far

Management Plans focus on critical elements and identify practical alternatives to replacement› Save time and costs

Prudent and feasible alternatives already outlined for us based on type and transportation requirements Use as a guide for Section 4(f) Alternatives Analysis

May require core samples or other specific data to further assess preservation potential

ODOT’s Historic Bridge Maintenance & Preservation Guidelines is a manual that outlines effective and economical procedures that will prolong the useful life of historic bridges

Based on our 2009 update study, bridges are now categorized as National Register eligible/listed or “Not eligible”

The historic status on buckeyeassets.org PDF reports is NR Status: Y or N

Funding preservation and more creative mitigation practices› Partnership with Office of Local Projects to

help channel more TEA enhancement funding to the identified highly significant structures that “need a friend”, and have real preservation potential

› Apply mitigation costs from an historic bridge replacement toward maintenance items on another more significant local bridge

› Working with FHWA to create a historic bridge fund for maintenance and preservation
