Why does Route 66 run as it does?
The purpose of the creators of US 66 was to link the heartland of America with the Pacific coast.
Chicago was a major railroad and Great Lakes shipping hub and at that time it was the coutry's second most populous city (after New York).
Los Angeles had surpassed San Francisco to become California's most populous city in 1920. And shortly after US66 was created it became the 5th most populous city in America.
Cyrus Avery (read more about Avery in our History of Route 66 page)who was the mastermind behind US 66 and the Federal Highway System promoted its virtues:
- The shortest and most direct route from the Great Lakes to the Pacific Coast
- No high mountain passes across the Rockies, passes that could get snowed in during winter
- Key link across Illinois prairies and Missouri's Ozarks
- Outlet for the lead and zinc mines in the tristate region (OK, KS, MO)
- Link to the oilfields of Oklahoma and northern Texas
They also lobbied for it to be paved and straighter than the Ozark Trail and National Old Trails "roads" along which it was aligned when it was created in 1926.

Legacy of Route 66
Route 66 has been part of the American way of life since it was created in 1926 until its demise in 1985.
Spanning the country from the Great Lakes to the sunny shores of the Pacific Ocean, it was the highway that led people all across the nation to new lives, jobs, a journey that was one of survival during the Dust Bowl of the 1930s, of hope and progress during the post World War II years, and of fun, joy and vacations during the 1950s and 60s.
