章节摘录

　　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 High way 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-mite web of highways， bridge， 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 road ways， 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.　　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 Washing ton， met many of the nations 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 term 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.
