Historic highway bridges

Federal and state laws and regulations mandate that the transportation project development process take into consideration cultural resources that may be affected by project activities. This includes impacts to bridges and roadways at least 50 years old and deemed significant according to the National Register of Historic Places (NRHP) criterion for listing. The Washington State Department of Transportation (WSDOT) maintains an inventory of historic bridges and highways that have been evaluated for the NRHP.   

In accordance with the National Historic Preservation Act of 1966 (NHPA), its implementing regulation 36CFR800, and 23 U.S.C. 144, WSDOT is required to inventory and assess the eligibility of historic-age bridges for listing in the National Register of Historic Places. Washington State highway bridges built before 1971 have been inventoried and evaluated for listing on the National Register. WSDOT maintains a list of Washington State Historic Highway Bridges that have been recommended, nominated, determined eligible or listed on the NRHP. To determine if your project will impact an NRHP eligible historic bridge, contact your regional CRS to conduct an evaluation. The WSDOT Cultural Resources Compliance Guidance for Historic Bridge Projects (pdf 113 kb) provides an illustration and step-by-step guide to the Section 106 and Section 4(f) review process per the Statewide Programmatic Agreement.

Interstate Highway Bridges

The 2005 Section 106 Exemption Regarding Effects to the Interstate Highway System by the Advisory Council of Historic Preservation (ACHP) excludes the majority of Interstate Highway Features from consideration as a historic property under Section 106 of the National Historic Preservation Act (NHPA). FHWA maintains a list, by state of Nationally and Exceptionally Significant Features of the Federal Interstate Highway System not subject to the ACHP’s Exemption. This list includes interstate highway bridges and segments of highway containing bridges determined by the Federal Highway Administration (FHWA) to be of exceptional national significance in Washington State.

Post 1945 Concrete and Steel Bridges

The Program Comment for Common Post-1945 Concrete and Steel Bridges issued by the ACHP in 2012 eliminates the historic review requirements under Section 106 of the NHPA for common (mass produced) post-1945 concrete and steel bridges and culverts. The intent of the Program Comment is to streamline the review process for those structures lacking distinction; have not previously been listed or determined eligible for listing on the National Register; and are not located in or adjacent to historic districts. A list of exceptions to the Program Comment (Bridge Program Comment Excepted Bridges List), identified by state, include common post-1945 concrete and steel bridges and culverts of exceptional quality that remain subject to Section 106 review.

Historic Bridge Sales and Donations

Federal regulations (23 U.S.C. 144) require WSDOT to provide an opportunity for the adoption or reuse of historic bridges, determined significant according to National Register criteria, and scheduled for replacement. Proposals must demonstrate the recipient can successfully relocate or preserve the bridge in place, to maintain its historic character.

For more information about acquiring a historic bridge through sale or donation, please visit our Bridges for sale or donation webpage.

Washington State Historic Highway Bridges

Bridges shown are listed (NR) in the NRHP, determined eligible for listing (NR DE), have been nominated or recommended eligible for inclusion in the NRHP. HAER bridges have been documented by, or for, the Historic American Engineering Record or the Department of Archaeology and Historic Preservation's Level 2. Interstate bridges are FHWA's Features of the Interstate System of Exceptional National Significance. 

Bridge sufficiency ratings are shown as FO (Functionally Obsolete), SD (Structurally Deficient, or N (Neither or Does Not Apply).
