It was built in 1877 and is long. The bridge was placed on the National Register of Historic Places in 1980, and had a major restoration in 1998. The Cogan House bridge is named for the township and village of Cogan House, and is also known by at least four other names: Buckhorn, Larrys Creek, Day's, and Plankenhorn. The Cogan House Covered Bridge was constructed by a millwright who assembled the timber framework in a field next to the sawmill, before it was reassembled at the bridge site. It was the only bridge on Larrys Creek that survived the flood of June 1889, and one of only a handful that were left intact in the county. Although the bridge used to carry a steady flow of tannery and sawmill traffic, the clearcutting of the surrounding forests meant the end of those industries by the early 20th century. Since then much of the surrounding area has reverted to second growth forest, and the one-lane bridge is now on a dead end road in a remote valley with little traffic. It is the oldest and longest of the three covered bridges remaining in the county. Despite the 1998 restoration and other repairs, as of 2009 the bridge structure's sufficiency rating on the National Bridge Inventory was 17.2 percent and its condition was deemed "basically intolerable requiring high priority of corrective action".〔 ==Names== The covered bridge is south of Pennsylvania Route 184 on Campbell Road (Township Road 784), past the intersection with Covered Bridge Road.〔 Its official name on the National Register of Historic Places (NRHP) is "Cogan House Covered Bridge".〔 It is the only covered bridge ever built in Cogan House Township and the name comes from the township, as well as the village of Cogan House, which is northeast of the bridge.〔 Cogan House Township and the village are named for David Cogan, who settled on Larrys Creek in 1825. Cogan was one of the few settlers in the area for many years and grew tired of living nearly alone in the wilderness. In 1842 he abandoned his homestead, as did a neighbor named Carter. Their houses were used by hunters and travelers and the name Cogan's House was given to the area. Cogan House Township was formed from parts of Jackson and Mifflin Townships on December 6, 1843.〔 Since the bridge's 1998 restoration, the Lycoming County Commissioners have officially called it the "Buckhorn Covered Bridge".〔 The name comes from the bridge's location at the base of Buckhorn Mountain,〔 and from the road to the former village of Buckhorn, which crossed the creek on it.〔 This is the name used on the erected by the commissioners to mark its restoration and placement on the NRHP, despite the different name used on the Register itself. The commissioners chose "Buckhorn Covered Bridge" based on one of the names used in Benjamin and June Evans' 1993 book ''Pennsylvania's Covered Bridges: A Complete Guide''.〔 Historically, the commissioners used "Cogan House Covered Bridge" as the official name.〔 Historian Milton W. Landis uses "Larrys Creek Covered Bridge" since it crosses Larrys Creek, and notes this was the name used by other local historians.〔〔 Larrys Creek is named for Larry Burt, who was the first settler at the mouth of the creek when the surveyors came through in 1769.〔 Landis acknowledges the "Cogan House" name, and says the bridge has also been known by the names of "several tenants who lived in the little farm adjacent" to it.〔〔 While Landis does not give these different names, two other names for the bridge are known and may come from some of these tenants. The first of these is "Day's Bridge" and it is clear that this is another name for the Cogan House Covered Bridge.〔 (No author)〕〔 The second of these, "Plankenhorn Bridge", is a name in a list of existing and vanished covered bridges in Lycoming County. Although the association of this name with the Cogan House Covered Bridge is not made explicitly, it is described as still standing on Larrys Creek and being north of a bridge in Mifflin Township. This is the only known covered bridge that meets those criteria.〔 (No author)〕 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「Cogan House Covered Bridge」の詳細全文を読む スポンサード リンク
