Answer:
Benefits of highways to humanity or the world
Explanation:
The role of the Dwight D. Eisenhower National System of Interstate and Defense Highways and the Nationals Highway System (NHS) – in growing and sustaining our American economy – is manifest. The interstates, now part of the NHS, have supported the rapid expansion of our post-World War II economy, whether it be embodied in manufacturing, tourism, suburban and urban growth, or the revitalization of rural areas. But the role of the NHS is changing, even as it sustains our economy and positions it for the coming generations. For example, in the case of “just-in-time” truck deliveries, the highway performs so well that it has become the warehouse – as well as the link – between producer and consumer. Just-in-time deliveries help manufactures manage inventories to enhance cash flow, but it’s done at the expense of the road system. The daily commutes have changed, with the suburb-to-suburb commute outstripping the conventional suburb-to-city commute. And today, it not unusual, for example, for workers “inside the Beltway” of Washington D.C. to make their daily commutes from Pennsylvania or West Virginia. Now, the most significant transportation hubs of the future will be multimodal in nature, with Interstate-type highways linking with rail transfer facilities, airports or seaports, connected perhaps by new-era transportation corridors that bundle separate passenger lanes with truck lanes, high-speed rail, and much more and our superb, ever-changing Interstate system makes it all possible.
