What is the significance of Route 66 in Oklahoma history?

Route 66 holds significant importance in Oklahoma history primarily due to its role in contributing to economic development and facilitating migration during the Dust Bowl. Established in the 1920s, Route 66 became known as the "Main Street of America," serving as a critical artery for those traveling west in search of better opportunities during the Great Depression and the environmental catastrophe known as the Dust Bowl.

During this challenging time, many families fled their homes, particularly from states like Oklahoma, which faced severe drought and agricultural collapse. The highway enabled these displaced individuals to migrate towards California and other western states, offering a sense of hope for new beginnings and livelihoods. The influx of travelers along Route 66 also spurred the growth of communities and businesses in Oklahoma, contributing to its economic development.

The other options pertain to historical aspects that are either less significant or inaccurate in the context of Route 66's specific role in Oklahoma. While railways and roads have played important roles in transportation and relocation, Route 66's legacy is predominantly tied to migration patterns and economic change during a period of crisis.
