The Columbia River (Astoria) Bridge, also known as the Astoria-Megler Bridge is just over four miles long (21,474 feet), and is the longest bridge in Oregon. The main span is a 2,468-foot steel cantilever through truss, and is flanked by five steel deck trusses, one hundred forty 80-foot concrete deck girder spans, and, at the Washington end of the bridge, seven 350-foot steel through truss spans. The bridge was designed jointly by the Oregon and Washington state highway departments. Construction was begun in 1962, and completed in 1966.
又称阿斯特拉-梅格勒大桥,全长21474英尺(将近4英里),是美国俄勒冈州最长的桥.
有主跨度2468英尺悬臂式钢桁架,其两侧五个钢制桥面桁架.140个80英尺混凝土桥墩,在华盛顿州的尾段有7个跨度350英尺的钢桁架.
大桥由俄勒冈州和华盛顿州公路部门联合设计,工程始于1962年,落成于1966年.
以此结束了从1840年开始的轮渡摆渡和从上游才能渡过哥伦比亚河的历史.

[ 本帖最后由 清水明石 于 2008-3-31 22:19 编辑 ] 愚人节有特别节目，
不过好像已经过期了，对不住大家了。
in past years we have snuck in a fictitious bridge on April Fools Day and then replaced it with the real April Bridge of the Month after a few days.This year's travel plans prevent sneaking the bogus bridge in on April 1st, so here is the plan: April Fools Bridge 2008 Image is being posted on March 14 at 10PM Pacific Daylight Time.
The image is a composite of 3 pictures from various locations The first 20 contestants who correctly identify the bridge name and location of 2 of those 3 images will receive a (small) prize acknowledging their expertise.
The real April Bridge of the Month will be posted around April 5th and you will have the rest of the month to compete for a copy of "Bridging the World."

（怎么论坛没有表情了？？） 愚人节的答案 出来啦
The 2008 April Fools Day image was a combination of the remains of the Bridge at Remagen plus the steel arch from New York's Hell Gate Bridge. (The third source was a piece of shoreline of the Rhine at Koblenz). Only 6 participants were succesfull in identifying 2 of the images. Pat Battles, David Böning, George Charnock, Ana Krecak, Robert Robillard and Ivo Swinnen will each be receiving a small prize.
桥是 德国 雷马根（Remagen ）鲁登道夫铁桥（Ludendorff Bridge ）遗址 + 美国 纽约的Hell Gate Bridge Ludendorff BridgeRemagen
The Ludendorff Bridge (in WW-II literature, frequently called the Bridge at Remagen) was a railroad bridge across the Rhine in Germany, connecting the cities of Remagen and Erpel between two ridge lines of hills flanking the river. Remagen is situated south of Bonn.
The bridge is famous for its capture on March 7th—March 8th 1945 by Allied forces in the Second World War as its capture allowed the allies to establish a bridgehead across the Rhine and expand that into a lodgement in a desperate and frantic battle where both sides raced to reinforce changing the entire nature of the conflict on the Western Front. A lodgement across the Rhine anywhere presented the allies with an opportunity to return to a battle of maneuver and conserve men, while the Third Reich had almost succeeded in establishing a stable defensive line along the rough terrain of the Rhine valley buying time to restore strength and prolong the war.
The bridge capture was an important strategic turning point during WWII because it was the only remaining bridge which led over the Rhine River into Germany's heartlands and was also strong enough that the Allies could cross armor and truck loads of supplies immediately. Once captured, the German efforts became desperate measures to knock it down, damage it beyond use, and slow allies use of it while the allies worked to defend it, expand their bridgehead into a lodgement sufficiently large so that the Germans could no longer attack it by artillery, and keep it in repair despite the ongoing damage inflicted by battle damage while using it to support the lodgement expansion.
The ensuing meeting engagement went on for more than a week during which it understandably triggered a huge artillery duel, a desperate air battle (effectively finishing the Luftwaffe), and totally scrambled troop dispositions for both sides along the entire defensive front along the Rhine as both sides reacted to the capture. One side effect of those redeployment was that the allies were able within the fortnight to establish other lodgements using pontoon bridges in several other sectors of the rhinish front, again complicating the defense for the Germans and hastening the collapse.
中文介绍 ：
希特勒曾说过这样一句话：“有两个“桥头堡”决定了我们德国的命运，一个在诺曼底，而另一个在雷马根！”
1945年3月6日，美第六军攻占科隆，从而在荷兰的涅米根到科隆之间一百多英里的区域形成了盟军首尾呼应的连续战线。科隆以南，德第五装甲集团军面对的是美第一和第三军，后者正快速突破德军阵地。当攻占科隆以后，美军没有满足已有的胜利。击溃德第五装甲集团军后，如果继续穷追猛打，很可能在德军休整前就将它们包围。目前这是可行的。三月七日，美第七军从科隆出发向波恩发起进攻，美第三军，则去夺取艾尔河上的桥梁。当天中午，美第七装甲师〔隶属美第三军〕的Ｂ战斗团听到一个振奋人心的消息：雷马根地区莱茵河上的鲁登道夫铁桥还未被德军炸毁。要完整地夺取该桥，这可是天赐良机。因此，美第七装甲师向雷马根扑去。下午，当美第七装甲师准备过桥时，对面的德军正要引爆炸桥，但未能成功，这样美第七装甲师成功的渡过了莱茵河，并建立了稳固的桥头堡。
雷马根大桥被美军占领，“如同一把手术刀，在德国人的莱茵河防线上切开了一道口子！”河对岸镇守厄尔波尔镇的100多名德军工兵发起了自杀式的冲锋，几乎全部阵亡！德军的大炮猛烈轰击大桥和美军架设的舟桥，甚至出动了当时刚刚研制成功的喷气式飞机来炸桥，后来还发射了11枚V1飞弹，但令人不可思议的是这一切都没能奏效；与此同时，美军工兵夜以继日地拼命加固受损的桥身，保证大批步兵和坦克源源不断地挺进德国腹地——希特勒十分恼怒，下令所有与雷马根大桥失守有关联的人员，除一人外全部枪决！
由于主桥拱在德军的爆破中受到致命损伤，加之连续多日的人员车辆通过，大桥不堪重负。3月27日下午15：00，就在宣布大桥关闭不到一小时后，雷马根大桥轰然坍塌，造成当时正在执行维修任务的28名美国工兵死亡，另有63人受伤...... 2008年 4月 的大桥
