The Stark Covered Bridge is a historic wooden covered bridge over the Upper Ammonoosuc River in Stark, New Hampshire. It carries a connecting roadway which joins the Northside Road to New Hampshire Route 110. The bridge was built in either 1857 or 1862 (sources differing), replacing a floating bridge that had been located a short way upstream. It is a two-span Paddleford truss bridge, which is a regional variant of the Long truss. It is long with a span of , and is wide, carrying an wide roadway and two sidewalks. The shore ends of the bridge rest on abutments of granite stone, while the center of the bridge is supported by a reinforced concrete pier, which is flared on the upstream side to deflect debris. The bridge is reinforced with steel beams, giving it a carrying capacity of 15 tons.〔(【引用サイトリンク】title=NRHP nomination for Stark Covered Bridge )〕 When originally built, the central pier was also of granite, but it was washed away, along with the bridge, in 1890 or 1895. The bridge survived the disaster, and was placed again on its abutments, and reinforced with laminated arches that were thought to eliminate the need for a central pier. This configuration survived untile 1946, when sagging in the bridge prompted construction of a temporary wooden central pier. The bridge was rebuilt in 1954, adding the present concrete pier and the steel stringers, and removing the laminated arches.〔 The bridge was listed on the National Register of Historic Places in 1980.〔 ==See also== *National Register of Historic Places listings in Coos County, New Hampshire *List of New Hampshire covered bridges *List of bridges on the National Register of Historic Places in New Hampshire 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stark Covered Bridge」の詳細全文を読む スポンサード リンク
