The Wright's Ferry Bridge carries U.S. Route 30 (US 30) over the Susquehanna River between Columbia and Wrightsville, Pennsylvania. Its name commemorates the first ferry crossing the Susquehanna (Wright's Ferry); it is considered a Columbia–Wrightsville Bridge, the fifth, The fourth Columbia–Wrightsville Bridge it augments (and might have replaced) is still carrying the Lincoln Highway.〔 group=notes>Most regions replace addresses enumerated as ''Lincoln Highway'' or ''National Pike'' with terminology prefixing (the natural language prefix) "Old" creating expensive but temporary confusions and dislocations for businesses and residents as everyone adjusts to the new addresses. So bypassed roads throughout much of the country have changed the local references and mailing addresses (names, in other words) for their two lane (1913 act based) era federal highways such as Old Lincoln Highway, or Old National Pike. The renamed 'Old Road Name' labels sometimes are given an auxiliary highway designation by the DOT, see Bannered routes of U.S. Route 30, for such alternate routes. The Route 30 stretch near this bridge must locally be colloquially called New Lincoln Highway, for the local politics retained the Lincoln Highway title on the original roadbed, locally now Pennsylvania Route 462. The thirty miles of Route 462 are currently labeled on internet digital map software still as the Lincoln Highway. 〕 Also informally known locally as the Route 30 bridge, it was commissioned by the Commonwealth of Pennsylvania in the 1960s to relocate US 30 and bypass the river towns of Wrightsville and Columbia. Construction started in March 1969 with G.A. & F.C. Wagman, Inc. as the general contractor. It was completed in 1972 at a cost of $12,000,000 and opened November 21, 1972 under its present commemorative historical name (Wright's Ferry being both the historic Ferry's and one of Columbia's former names). It is constructed of reinforced concrete and steel and has 46 equal sections on 45 piers. US 30 crosses it as a divided four-lane roadway. About a year after its opening, the bridge was shut down briefly so that an experimental weather-resistant coating could be applied to its roadway. Tolls were never collected on this bridge, the sixth to cross the river in this general location. ==See also== * List of crossings of the Susquehanna River 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「Wright's Ferry Bridge」の詳細全文を読む スポンサード リンク
