SECTIONSIXResults of Field InvestigationsThe American Bridge Company is among America‘s premier bridge builders. Formed in 1870,the company is responsible for two of the most famous arch bridges in the United States: theBayonne Bridge in New Jersey (1932) and the New River Gorge Bridge (1977) in West Virginia.The MD 213 Bridge over the Chesapeake & Delaware Canal is a notable example of work by thecompany due to the rarity of its type.MD 213 serves as the western boundary of the South Chesapeake City Historic District, listed inthe National Register. The MD 213 Bridge is located just north of the northwest corner of thisdistrict. The MD 213 Bridge is not recommended eligible as a contributing resource in thishistoric district as its construction date of 1949 places it outside of the district‘s 1829-1900period of significance. The South Chesapeake City Historic District is associated with the periodof private ownership of the Chesapeake & Delaware Canal until 1919. The MD 213 bridge wasbuilt by the US Army Corps of Engineers which assumed control of the canal and its bridgesafter 1919.National Register-eligibility under Criterion D was not investigated as part of this study.\15-SEP-11\\ 7-18

Metal joint plates are located at the meeting point of eachof the spans and at each end of the bridge. It appears that the deck has been surfaced withblacktop within the past ten years. The substructure of the bridge is composed of two large bents.Each bent consists of seven concrete-filled, fluted, steel Monotubes, 18-inch diameter columns.The columns are capped by concrete slabs that support nine concrete beams that run the length ofthe bridge and support the concrete deck.
