Answer:
The enactment of laws to create a national highway system led to the connecting of smaller roads to form Route 66.
Step-by-step explanation:
In 1926, the federal government enacted the Federal Highway Act, which called for the creation of a national highway system that would connect major cities across the country. As part of this effort, smaller roads and highways were connected and improved to form a network of highways that would span the entire country. One of the highways included in this system was Route 66, which connected Chicago, Illinois to Santa Monica, California.
Route 66 became an important route for travelers and businesses, and it played a significant role in the growth of the trucking industry. As a result, it became known as the "Main Street of America" and an iconic symbol of American travel and adventure.
