| 説明 | Built in 1847-1849, this Suspension Bridge was designed by Charles Ellet, Jr., and constructed to carry the National Road, which began east of the city in Washington, DC, over the main channel of the Ohio River. The bridge was the longest single span bridge in the world at 1,010 feet until the Roebling Bridge in Cincinnati was completed in 1867. Ironically, Roebling had designed by competing bridge concept for the Wheeling Suspension Bridge, which was rejected as it would have required towers in the river, narrowing the navigation channel. The bridge was contested from the time of its completion by stakeholders from Pennsylvania, which found the bridge too low for the tall stacks of steamboats on the river, which was further supported by the US Supreme Court’s ruling in the 1851 case “Pennsylvania v. Wheeling and Belmont Bridge Company,” which initially found in favor of Pennsylvania, but later reversed this decision, claiming that Pennsylvania had no jurisdiction over Virginia. Instead, it was legally mandated that steamboats on the Ohio River with tall stacks have hinges to allow for the stacks to be lowered when passing by Wheeling.The bridge’s original deck collapsed during a storm in 1854, and was rebuilt in 1856 with a narrower deck, despite continuing opposition from Pennsylvania, which had opposed the bridge’s construction, declaring it an “obstruction to navigation,” and attempted to have the reconstruction halted. The bridge’s deck was restored to its original width in 1859-1860, under the direction of engineer William K. McComas. In 1871-1872, the bridge’s sidewalks and cables were reconfigured under the direction of Washington A. Roebling, the son of John Roebling, who later went on to design the Brooklyn Bridge in New York City. The bridge’s original wooden deck was replaced with a more durable steel grate deck in the 20th Century, and was superseded first by the Steel Bridge, which carried heavier traffic, including streetcars, to and from Wheeling Island between 1891 and 1962, and then by the Fort Henry Bridge, which was completed in 1955, and built to carry automobile traffic to and from Wheeling Island.The bridge features two stone made of rough-hewn stone blocks at each shore, with stone approaches and anchorages for the network of steel cables that support the bridge deck, a metal truss that supports the bridge deck and separates the sidewalks on the edges of the span from the vehicular lanes at the middle of the span, and angles downwards towards Wheeling Island from Downtown Wheeling, owing to the change in elevation between the two ends of the bridge, as well as the resulting different elevations of the towers. The bridge was designated a National Historic Civil Engineering Landmark in 1969, listed on the National Register of Historic Places in 1970, and was designated a National Historic Landmark in 1975. The bridge today is undergoing repairs after being closed for years due to the careless actions of multiple drivers operating large vehicles, which damaged the bridge by driving their heavy vehicles across it. |
