3. Section 1 ONE Methodolog ySECTIONTWOMethodology3.1 BACKGROUNDThe Historic Highway Bridges in Maryland: 1631 – 1960, Historic Context Report providedbackground and preliminary evaluation of post-World War II bridges, but did not fully addressthe important contextual issues that architectural historians, industrial historians, and engineershave examined during the past decade concerning the post-World War II road building era inMaryland. Therefore, SHA sought an update of its historic context that would provide the basisfor evaluation of historic bridges and begin a new phase of identification and evaluation with asample of 21 highway bridges built in Maryland between 1948 and 1960. In addition, the newcontext report would contain information about previous documentation efforts and build on thework contained in the Historic Highway Bridges in Maryland. The end product would includewell-developed information about technological innovations in bridge design and manufacturing,bridge manufacturing companies and designers, and important transportation advances or eventsfrom 1948 through 1960 in Maryland specifically and the United States generally.3.2 FIELDWORKTwenty-one highway bridges, representing the 1948 – 1960 period and 12 different bridge types,were chosen by the SHA, in consultation with MHT and FHWA, to be surveyed as part of theexpanded inventory of historic bridges. Hardlines architectural historians visited each bridge anddocumented the bridge and its appurtenances on Maryland Inventory of Historic Properties(MIHP) forms. In addition to completing each MIHP form, a MHT Determination of Eligibility(DOE) form with a detailed National Register eligibility evaluation was also completed for eachof the surveyed bridges. Each bridge was recorded on the appropriate USGS quadrangle map at1:24,000 scale and photographs were taken using 5 x7-inch, 35-millimeter black-and-white film,and 35-millimeter color slide film. Hardlines also obtained the MIHP inventory numbers foreach bridge from the MHT Inventory Registrar.3.3 RESEARCH AND CONTEXT UPDATEURS updated the historic context written in 1995 to include information regarding technologicalinnovations in bridge design and manufacturing, bridge manufacturing companies and designers,and important transportation advances or events from 1948 through 1960 in Marylandspecifically and the United States generally, as these themes correspond to National RegisterCriteria A, B, C and D. In order to develop a historic context update for the post-World War IIor mid-century-era bridges, historians from URS and Hardlines also conducted general andspecific research at a number of local, regional, and university repositories. In addition, thesehistorians researched county and/or SHA bridge maintenance records and construction plans, aswell as secondary sources of information, including the Office of Bridge Development‘s 2003Bridge Inventory and the most current list of county-owned bridges in Maryland. The historiansalso had access to the most current SHA Historic Bridge Inventory (1995 – 2001). Inspection ofprevious cultural resource survey reports, site forms, and other references was conducted eitherat MHT or at SHA. Other repositories of information used in the research effort include, but arenot limited to, the Enoch Pratt Free Library‘s Maryland Room, the Maryland State Archives, theHistorical Society of Maryland Library, New Jersey State Library, New York Public Library, and\15-SEP-11\\ 3-1

The inspected documents included historic maps, reports, articles,papers, historic photographs, monographs, and books.3.4 PROJECT PERSONNELURS Architectural History Team Leader Geoffrey Henry served as Principal Investigator andProject Manager for the Historic Context Update and Survey of 21 1948-1960 Highway Bridgesin Maryland Project for the SHA. He directed the research, evaluation, and writing of the historiccontext for this project. URS Architectural Historians Mark Edwards, Amy Barnes, FredHolycross, Craig Tuminaro, Aaron Levinthal, Ellen Jenkins, and Marvin Brown conductedresearch, wrote individual bridge histories, and evaluated the 21 bridges for NRHP-eligibility.Fred Holycross, Aaron Levinthal, and URS Historian Ingrid Wuebber conducted historicresearch and wrote the updated historic context for 1948-1960 highway bridges in Maryland.Hardlines Architectural Historian Charissa Wang served as Project Manager for the fieldworkphase of this project. Fieldwork was conducted by Hardlines Architectural Historians/HistoriansRoy Hampton, Stan Popovich, Amy Case, and Mary Crowe. The survey team was divided intotwo groups to conduct the survey fieldwork: one group working in the eastern half of Maryland;the second group working in the western half.The historians and architectural historians meet the Secretary of Interior’s ProfessionalQualifications Standards for history and architectural history, published in 36 CFR Part 61(Appendix C).3.5 PREVIOUS DOCUMENTATIONFour highway bridges built during the 1948-1960 period in Maryland have been previouslysurveyed and evaluated for NRHP eligibility. These bridges were surveyed and evaluated as partof the Section 106 process, which mandates consideration of the effects to NRHP-listed or -eligible resources (including bridges) from federally funded actions undertaken by SHA. Table 3lists these previously surveyed and evaluated highway bridges.Bridge #Table 3 – Previously Surveyed 1948–1960 Highway Bridges in MarylandBridge Name/Location0400800 MD 231 over thePatuxent RiverMIHP/DOE #CT-1214County Date Built NRHPEligible?Calvert andCharlesNRHPCriterion1950/1951 Yes Criterion C2200302 Business US 13 over theBaltimore & OhioRailroad TracksWI-222 Wicomico 1930; SecondSpan-1951YesCriterion C0106600 Blue Bridge/ MD 942over the North Branch ofthe Potomac RiverAL-IV-A-153Allegany1954; renovated1996YesCriterion CF-10700 Doubs Road over theTuscarora CreekF-1-215 Frederick 1935; rebuilt1950NoNot Applicable\15-SEP-11\\ 3-2
