Why government officials decided to build route 66 through the Southwest rather than straight west from Chicago?

Government officials decided to route Route 66 through the Southwest rather than straight west from Chicago to promote economic development in less populated areas, enhance accessibility to rural communities, and take advantage of existing road networks. The chosen path also provided a more scenic and enjoyable journey, attracting tourists and boosting local economies. Furthermore, the Southwest's varied terrain and climate offered unique travel experiences that appealed to motorists. Ultimately, this decision aimed to create a vital artery for commerce and travel across the United States.
