Immigrant farm workers during the Dirty Thirties used a route that connected what states?
U.S. Route 99 U.S. Route 99 (US 99) was a main north–south United States Numbered Highway on the West Coast of the United States until 1964, running from Calexico, California, on the US–Mexico border to Blaine, Washington, on the U.S.-Canada border. It was assigned in 1926 and existed until it was replaced for the most part by Interstate 5. Known also as the "Golden State Highway" and "The Main Street of California", US 99 was important throughout much of the 1930s as a route for Dust Bowl immigrant farm workers to traverse the state. Large portions are now California's State Route 99 (SR 99), Oregon Route 99, 99W, 99E and Washington's SR 99. The highway connected to British Columbia Highway 99 at the Canada–US border.
Cooke's Wagon Road Cooke's Wagon Road or Cooke's Road was the first wagon road between the Rio Grande and the Colorado River to San Diego, through the Mexican provinces of Nuevo México, Chihuahua, Sonora and Alta California, established by Philip St. George Cooke and the Mormon Battalion, from October 19, 1846 to January 29, 1847 during the Mexican American War. It became the first of the wagon routes between New Mexico and California that with subsequent modifications before and during the California Gold Rush eventually became known as the Southern Trail or Southern Emigrant Trail.
