Currently, the Posey tube carries Oakland-bound traffic under the Estuary, while the Webster tube carries traffic bound for Alameda. The Posey tube is the second-oldest underwater vehicular tunnel in the US, preceded only by the Holland Tunnel. ==Construction== The Posey tube, an immersed tube completed and opened to traffic on October 27, 1928, was named after George Posey, Alameda County Surveyor during the tunnel's planning and construction, and also chief engineer on the construction project. The Webster Street tube opened in 1963 to deal with the increased traffic between Oakland and Alameda. Both are immersed tubes, constructed by sinking precast concrete segments to a trench in the Estuary floor, then sealing them together to create a tunnel. The Posey tube replaced a swing bridge that interfered with maritime traffic. The ventilation buildings that house the exhaust and fresh air fans are built in an art deco style. The ventilation of toxic vehicular exhaust fume design was modeled on that of the Holland Tunnel's ventilation system, and Ole Singstad (who had designed the pioneering ventilation system of the Holland Tunnel) consulted.〔(Saga in Steel and Concrete, pp. 191–202 )〕 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「Posey and Webster Street tubes」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
