STATE HISTORIC BRIDGE INVENTORY AND EVALUATION 2024 UPDATE • Replaced Historic Bridge:These include 13 NRHP-eligible and NRHP-listed bridges previously evaluated in 2013 that have been replaced by new bridges. Two of these 13 bridges fell within Kauai Belt Road (North Shore Section) and received updated inventory forms. Bridges that did not receive updated inventory forms have had their 2013 SHBIE inventory forms carried over into this 2024 SHBIE. Bridge inventory forms have been organized into appendices by island with accompanying matrices and will appear in the following order: Appendix A—Island of Kauai Appendix B—Island of Oahu Appendix C—Islands of Maui and Molokai Appendix D—Island of Hawaii Each appendix is divided into three sections, 1) 2024 Updated Bridge Matrix(State-and County-Owned), 2) 2013 State Bridge Matrix, and 3) 2013 County Bridge Matrix Two additional appendices, Appendix E and Appendix F, provide additional information and documentation carried over from the 2013 SHBIE and was updated when necessary. Appendix E—Supplemental Information, is carried over from the 2013 SHBIE and includes a glossary of terms, a list of significant bridge designers, and bridge rehabilitation guidelines. The 2024 SHBIE has included the preservation plans for Kuhio Highway and Hana Highway in Appendix E. Appendix F—National Register Nominations, Historic Districts and District Recommendations, includes NRHP nomination forms organized by island. These forms have been carried over to this inventory, except for bridges that have been replaced, in addition to NRHP nomination forms that have been prepared after 2013. Appendix F also includes matrices for NRHP historic districts and 2013 SHBIE proposed historic districts. DATA ANALYSIS AND INVENTORY FORM UPDATES For this update, investigation methods included review of bridge inspection reports and previous bridge inventory surveys; information obtained through HDOT records, online records, and local repositories; Historic American Engineering Record (HAER) and NRHP documentation;and photographs from HDOT Districts and County DOTs.
