| 説明 | The Burlington Bridge carries double tracked rail lines across the Mississippi River between Burlington, Iowa, and Gulf Port, Illinois. The bridge is currently owned by BNSF Railway as part of its Chicago to Denver mainline. It is somewhat controversial in that its swing-span only allows one barge to pass at a time and the US Coast Guard has declared it a navigational hazard. The bridge is planned to be replaced with a vertical lift bridge to double the width of the navigational channel once about $40 million is appropriated. As of 2005, around half of the estimate has been approved. Amtrak's California Zephyr crosses this bridge. The original bridge at this location was constructed in 1868. It was reconstructed in 1893 in its current form. On May 1, 2008, 5 fully loaded barges broke loose during a period of high water. One struck the bridge and became lodged under it. The bridge was closed until midday on May 2, when one track was opened after it was deemed safe. The barge was removed during the afternoon of May 3 and the other track was reopened that evening bringing the bridge back to full use to carry the dozens of trains that cross it daily. Not counting this incident, it has only ever been closed twice, once in 1993, and again in June, 2008, due to severe flooding.As of late 2009, BNSF Railway has begun work to replace the bridge. As of October 2010 a new span section can be seen directly south of the existing structure. |
