By the 1970s, more than 1 million Americans had been forced to relocate for highway construction.
As local communities were cut off due to highways, the number of areas where communities collapsed and declined increased.
Naturally, in this process, residential areas where many people of color, including blacks, lived were often selected as highway sites.
In addition, the large-scale highway network has changed the urban structure into a form unsuitable for walking.
It also caused the United States to become a country where one cannot live without a car.
