Early in the 20th century, most of the streets and roads in the U.S. were made of dirt, brick, and cedar wood blocks. Built for horse, carriage, and foot traffic, they were usually poorly cared for and too narrow to accommodate  automobiles.
With the increase in auto production, private turnpike （收费公路） companies under local authorities began to spring up, and by 1921 there were 387，000 miles of paved roads. Many were built using specifications of 19th century Scottish engineers Thomas Telford and John MacAdam （for whom the macadam surface is named）, whose specifications stressed the importance of adequate drainage. Beyond that, there were no national standards for size, weight restrictions, or commercial signs. During World War I, roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in the U.S. Army’s first transcontinental motor convoy （车队）, he noted: “The old convoy had started me thinking about good, two-lane highways, but Germany’s Autobahn or motorway had made me see the wisdom of broader ribbons across the land.”

    20世纪早期， 美国的大多数街道和公路是用泥土、 砖块和杉木板铺设的。这种为骑马、 赶车和步行设计的道路通常养护不佳且过于狭窄， 并不适合汽车行驶。
    随着汽车产量的增加， 私营的收费公路公司在地方政府的支持下如雨后春笋般涌现出来。截止到1921年， 一共铺设了38.7万公里的公路。其中， 大多数公路沿用了19世纪苏格兰工程师Thomas Telford和John MacAdam（碎石路面就是用他的名字命名的）提出的规范， 注重道路充分排水的能力。此外， 当时并没有针对道路规格、 限重和商业标牌的全国性标准。一战期间， 货车几乎把全国的公路都破坏掉了。当艾森豪威尔将军1919年从德国回来， 到美军第一个跨大陆机动车队任职时指出： “这些破旧的车队让我想起了良好的双车道公路， 而德国的机动车道让我见识了当地人的智慧。  



It would take another war before the federal government would act on a national highway system. During World War Ⅱ, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen per cent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The war also revealed that local control of highways had led to a confusing variety of design standards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36,000 pounds, while others restricted anything over 7,000 pounds. A government study recommended a national highway system of 33,920 miles, and Congress soon passed the Federal-Aid Highway Act of 1944, which called for strict, centrally controlled design criteria.
The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of the century. To build its 44,000-mile web of highways, bridges and tunnels, hundreds of unique engineering designs and solutions had to be worked out. Consider the many geographic features of the country: mountains, steep grades, wetlands, rivers, deserts, and plains. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of road use, and the nature of the underlying soil. Urban areas were another problem. Innovative designs of roadways, tunnels, bridges, overpasses, and interchanges that could run through or bypass urban areas soon began to weave their way across the country, forever altering the face of America.

    联邦政府真正开始建立国家公路系统是在另一次战争之后。二战时期， 对货车和新道路数量的需求大幅度上升。战争证明了道路对于防御工作的重要性。13%生产防御设备的工厂靠卡车运送原材料， 而几乎其他所有工厂半数以上的产品都由汽车运送。战争同样也暴露了各地建设的公路因设计标准的差异所带来的问题。就连联邦和各州的公路都没有一个基本标准。一些州允许卡车载重量高达3.6万磅， 但另一些却限制载重不可以超过7,000磅。政府的一项调查为此提出了一套33,920公里的公路标准体系， 国会通过了相关法案， 提出要建立严格的、 由中央控制的道路建设规范。
   美国国家公路系统最终于1956年动工， 它被誉为那个世纪最伟大的公共建设项目。为建设其4.4万公里长的公路—桥梁—隧道网， 数以百计的独特设计和解决方案涌现出来。要考虑到各地的地理特征： 山地、 陡坡、 湿地、 河流、 沙漠和平原。道路的各种变化包括地面的倾斜程度， 公路的载重负荷能力、 道路的使用强度、 地表土壤的种类。城市区域有另外的问题。能够穿过或绕过城市区域的道路、 隧道、 桥梁、 天桥和立交等创新设计在全国各地涌现出来， 彻底改变了美国的面貌。
 
 
 
Long-span, segmented-concrete, cable-stayed bridges such as Hale Boggs in Louisiana and the Sunshine Skyway in Florida, and remarkable tunnels like Fort McHenry in Maryland and Mt. Baker in Washington, met many of the nation’s physical challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway construction around the world, and were invaluable in improving the condition of urban streets and traffic patterns.
Today, the interstate system links every major city in the U.S., and the U.S. with Canada and Mexico. Built with safety in mind, the highways have wide lanes and shoulders, dividing medians or barriers, long entry and exit lanes, curves engineered for safe turns, and limited access. The death rate on highways is half that of all other U.S. roads （0.86 deaths per 100 million passenger miles compared to 1.99 deaths per 100 million on all other roads.）
By opening the North American continent, highways have enabled consumer goods and services to reach people in remote and rural areas of the country, spurred the growth of suburbs, and provided people with greater options in terms of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what they cherish most: personal freedom of mobility.

    像路易斯安娜的Hale Boggs大桥和佛罗里达的阳光高架桥一样的长跨度混凝土吊索桥， 以及像马里兰的Fort McHenry隧道和华盛顿的Mt. Baker一样的著名隧道， 它们的建设给国家带来了巨大挑战。交通控制系统和跨州建设的方法迅速影响了世界各地的公路建设， 并在改善城市街道和交通模式方面起到了非常重要的作用。
    现在， 跨州系统连接了美国所有的主要城市， 并连接了美国与加拿大和墨西哥。出于安全性的考虑， 公路都建有宽敞的车道和路肩、 分隔栏或路障、 较长的入口和出口车道、 为安全拐弯而设计的弯转， 以及限制出入的通道。高速公路上的事故死亡率仅为美国其他道路的一半。
    高速公路开放了美洲大陆， 让消费品和服务可以惠及边远的农村地区， 刺激了郊区的发展， 让人们在择业、 文化交流、 健康保健和其他方面有了更大的选择空间。总之， 跨州公路系统提供了个人最为珍视的东西： 个人迁移的自由。
 
 
 
The interstate system has been an essential element of the nation’s economic growth in terms of shipping and job creation: more than 75 percent of the nation’s freight deliveries arrive by truck; and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle. Not only has the highway system affected the American economy by providing shipping routes, it has led to the growth of spin-off industries like service stations, motels, restaurants, and shopping centers. It has allowed the relocation of manufacturing plants and other industries from urban areas to rural.
By the end of the century there was an immense network of paved roads, residential streets, expressways, and freeways built to support millions of vehicles. The highway system was officially renamed for Eisenhower to honor his vision and leadership. The year construction began he said: “Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bear—United States. Without them, we would be a mere alliance of many separate parts.”

    跨州系统是国家在海运和创造就业机会上最基本的经济增长成分之一： 全国75%以上的货运由卡车完成， 且大多数空运和铁路运输产品最终也将通过跨州系统由汽车运送到目的地。公路系统不但提供了海运通道， 影响了美国的经济， 还促进了维修站、 汽车旅馆、 餐厅、 购物中心等副业的增长。它重新规划了制造业的分布， 让工厂可以从城市迁移到农村。
    上世纪末之前， 美国已经建成了一个集公路、 住宅区街道、 高速公路于一体的巨大道路网络， 足以容纳数以百万计的车辆。公路系统被更名为艾森豪威尔以纪念其远见卓识和领导才华。在开工的那一年， 艾森豪威尔曾说： “通信和交通系统的联合力量是我国最重要的活力来源。失去它们， 我们仅是各自分裂的松散联盟。”
