Ever wonder how you can smoothly cruise across states without getting completely lost on backroads? Thank the Interstate Highway System! Officially known as the Dwight D. Eisenhower National System of Interstate and Defense Highways, this network is a marvel of engineering and planning.
Conceived in the 1950s and primarily funded by the federal government, the Interstate system revolutionized travel in the United States. It dramatically reduced travel times, boosted commerce, and even played a crucial role in national defense (hence the 'Defense Highways' part).
Even numbers generally run east to west, while odd numbers run north to south. Major routes have one or two digits, while 'auxiliary' routes, often bypasses or loops, have three. So next time you're merging onto I-95 or cruising down I-80, take a moment to appreciate the massive undertaking that made modern road trips possible! It's more than just asphalt; it's a vital artery connecting our nation.
