The Hackensack Drawbridge (also known as the HD Draw)〔 was a double-track railroad movable bridge across the mouth of the Hackensack River between Jersey City and Kearny, New Jersey.〔(23 June 1940). (Authority Calls Hackensack Span Menace; Wants Drawbridge Rebuilt or Abandoned ), ''The New York Times'' (reporting that the Port of New York Authority was recommending that the bridge be either rebuilt or abandoned because it offered limited clearance)〕 It was operational until 1946, when a steamship crashed into it.〔 Built and maintained by the Central Railroad of New Jersey (CNJ),〔''Federal supplement'', pg. 341.〕 the bridge was part of the Newark and New York Railroad, a rail line characterized as the "costliest railroad" by W. H. Schmidt Jr., a columnist for ''Trains''.〔Schmidt, W.H. (May 1946), "Costliest Railroad Now Half Abandoned", ''Trains'', pg. 52.〕 Opened on July 23, 1869, the line was routed between terminals at Newark and Jersey City, where passengers could transfer to ferries to New York. It also crossed the Passaic River and the Kearny Point peninsula. Freight cars regularly traversed the bridge to deliver to various industries in Harrison.〔 ==Description== From the west side of the rail via tunnel, four tracks converged into three, and then into two tracks to pass over the Hackensack Drawbridge.〔''Railway signaling and communications'', pg. 465.〕 By 1913 the rail line, including the bridges across the rivers, was raised about to avoid conflicts with maritime traffic in the newly developing port The draw span of the PD Draw over the Passaic had been relocated upstream to create another bridge on an new alignment in 1912. By 1922, plans were made to improve the drawbridge's railway signal layout, increasing the number of interlocking levers, ground signals and bridge signals.〔''Railway signaling and communications'', pg. 476.〕 The drawbridge tower employed three levermen.〔''Railway signaling and communications'', pg. 478.〕 In 1897, a train carrying nearly 200 people derailed while crossing the bridge; there were no injuries. In 1940, the Port of New York Authority (now Port Authority of New York and New Jersey) cited the bridge as a navigational menace and called for its replacement.〔 With war impending, the War Department in 1941 asked CNJ to replace the swing bridge with a vertical lift to afford better access to the Federal Shipbuilding and Drydock Company on Kearny Point. Plans were made, but the shortage of steel prevented the project from being constructed. 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「Hackensack Drawbridge」の詳細全文を読む スポンサード リンク
