SECTIONSIXResults of Field InvestigationsThis bridge is one of the first two bridges completed in Washington County during the initialphase of construction of I 70 in Maryland.National Register of Historic Places Eligibility:The I 70 Bridge over Ramp E2, Westbound Lanes (MIHP # WA-IV-57, Bridge 2106104) iseligible for listing in the National Register under Criterion A on the state level with the period ofsignificance as 1960. The bridge is associated with the historical development of I 70, the firstInterstate in Maryland.It is one of the first two bridges completed in Washington County duringthe initial phase of construction of I 70 in Maryland. Work on the route began in Maryland in1956 with official construction beginning in 1960. A single-span, concrete rigid frame structure,the bridge was designed specifically for its site by Michael Baker, Jr., Inc., an engineering firmspecializing in bridge and highway design, for the Maryland State Road Commission in 1958.The company, which is still in existence, designed several bridges for the Maryland State RoadsCommission during this period.The I 70 Bridge over Ramp E2, Westbound Lanes is not National Register-eligible underCriterion B, as it is not associated with an individual significant on the local, state, or nationallevel.The I 70 Bridge over Ramp E2, Westbound Lanes is National Register-eligible under Criterion Con the local level as a notable example of the concrete rigid frame bridge type, a rare type inMaryland bridge design. The bridge was one of the last two examples of this type designed andconstructed in Maryland in the 1948-1960 period. This bridge type was popular in the popular inthe 1920s and 1930s but was constructed on a limited basis in Maryland into the 1950s and wasrarely used after the 1948-1960 period. The I 70 Bridge over Ramp E2, Westbound Lanes retainsall of the character-defining elements of its type intact. Further, it retains its integrity of location,design, association, setting, materials, workmanship, and feeling.National Register-eligibility under Criterion D was not investigated as part of this study.\15-SEP-11\\ 7-48

Section 6 SIX Conclu sion an d Reco mmendat ionsSECTIONSEVENConclusion and Recommendations8.1 SUMMARY AND CONCLUSIONSBetween May and September 2003, URS Corporation (URS) of Gaithersburg, Maryland andFlorence, New Jersey prepared an historic context of highway bridges from the 1948-1960period for the Maryland State Highway Administration (SHA). The project updated andexpanded upon the SHA‘s existing historic bridge context—Historic Highway Bridges inMaryland: 1631 – 1960, Historic Context Report (Paula Spero & Associates and Louis Berger &Associates, 1995). As part of the project, URS conducted a survey of 21 highway bridgesthroughout Maryland representing 12 different bridge types built between 1948 and 1960. Theproject had multiple goals: to develop more fully the historic context for bridges built inMaryland from the 1948-1960 period to reflect the technological innovations in bridge designand construction from this period; to establish criteria for the evaluation of the significance andintegrity of 1948-1960 highway bridges in Maryland for their eligibility for listing in theNational Register for Historic Places (NRHP); to document and record 21 highway bridges inMaryland from the 1948-1960 period representing 12 different bridge types; and to apply thiscriteria in the evaluation of the 21 surveyed highway bridges for their NRHP-eligibility.URS served as project manager and provided agency coordination. URS also conductedbackground research on the history of road building in Maryland from the 1948-1960 period,conducted research on the history of the individual surveyed bridges, and wrote the historiccontext. Hardlines Design Company (Hardlines) of Columbus, Ohio, serving as a subconsultantfor URS, conducted the field survey of 21 SHA highway bridges in Maryland. Fieldwork wasconducted from May to July 2003. Following the survey work, Hardlines completed MarylandInventory of Historic Properties (MIHP) forms.8.2 RECOMMENDATIONSURS evaluated the surveyed bridges on MIHP Determination of Eligibility (DOE) forms andrecommends 17 bridges eligible for the National Register of Historic Places under one or moreof the National Register Criteria. The bridges recommended eligible for listing in the NationalRegister are listed in Table 4 below.Table 4 – Highway Bridges in Maryland from 1948 – 1960 Recommended Eligiblefor the National RegisterMIHPID #BridgeName/LocationB-4632 I-895 Bridge over CSXRailroad TracksBA-2681CARR-1673CE-1083Wise Avenue Bridgeover Bear CreekMD 32 Bridge overLiberty ReservoirMD 213 Bridge overChesapeake &Delaware CanalCountyBaltimoreCityBaltimoreCarrollCecilBridgeTypeDate BuiltNRHPEligible?K-truss 1957 Yes A, CDouble LeafBasculeTrunnionSteel Deck(Warren)TrussMetal DeckArch (TiedArch)1948 Yes A, C1952 Yes A, C1949 Yes A, CNRHPCriterion\15-SEP-11\\ 8-1
