60 Based on the foregoing information, SHA has determined that the bridges constructed between 1948 and 1965 are not eligible for inclusion in the National Register of Historic Places under Criteria A (events), B (people), or C (engineering). This determination is made because the highways and bridges constructed between 1948 and 1965 have frequently been widened or altered, and those bridges and highways which have not been altered do not retain the ability to convey significance of the road building events that occurred during this time.
61 Eligible Bridges The following bridges have been determined eligible by SHA and MHT has concurred with the eligibility determinations. Information about bridges that the agencies have agreed are not eligible is included in Appendix A. MD 942 over the Potomac River, SHA Bridge No. 0106600 – Double thru arch bridge constructed in 1954, in Cumberland, Allegany County. Determined eligible in 2001 and a Preservation Priority Bridge. MD 151 over Patapsco and Back River Railroad and MD 151B, SHA Bridge No. 0309900 – Steel stringer/multi-beam or girder bridge – described as a metal girder bridge in the DOE form SHA prepared in 2002. The bridge was designed and constructed by the Bethlehem Steel Bridge Company and given to the SRC once MD 151 was constructed. The bridge stands at the entrance of the Bethlehem Steel Plant in Sparrows Point, Baltimore County. MD 231 over Patuxent River, SHA Bridge No. 0400800 –a movable swing bridge that was constructed in 1950/51 between Charles and Calvert Counties. Determined eligible in 1999. Old MD 32 over River Road, South Branch of Patapsco River, B&ORR (now CSX), SHA Bridge No. 1304600 – A three-span semi-monocoque composite aluminum box beam bridge near Sykesville that was closed to traffic in 2004. Determined eligible in 2000 and a Preservation Priority Bridge, because it is one of six aluminum bridges in the United <strong>State</strong>s. MD 32 over Liberty Reservoir, SHA Bridge No. 0604900 – a steel deck truss constructed as part of the Liberty Reservoir construction in 1952. Determined eligible in 2008 for its association with the Liberty Reservoir construction. US 113 Business over Purnell Branch, SHA Bridge No. 2300800, a three-span concrete slab bridge with decorative metal railings, constructed in 1952 and determined eligible in 2004. Also recommended as eligible from the 1948-1965 period are several bridges investigated by URS and Hard Lines Design in 2003 and 2004: MD 144 over the Monocacy River, SHA Bridge No. 1003803, MIHP No. F-3-205, a three span steel deck Warren truss bridge built in 1955 and altered in 1987 by the replacement of its deck and parapets as well as repairs to several stringers in the deck truss. MD 18B over Kent Narrows, SHA Bridge No. 1700600, MIHP No. QA-542, a twelve-span steel beam and bascule bridge, built in 1952 as part of the new Chesapeake Bay Bridge and US 50 improvements in Queen Anne’s County.
