Ocean-to-Ocean Bridge, Yuma, Arizona. Built in 1915, it was the first highway crossing of the Colorado River and the only rail crossing for more than 1200 miles. The bride and original letters from the 1920's were restored in 2002.
During the depression, because of the huge migration through Yuma toward the "promised land" of California, state police were posted on the Ocean-to-Ocean Bridge. If travelers could not show that they had money in their pockets or a firm job in California, they were not permitted to cross the river. Many people turned around and settled in Yuma - the origin of the neighborhood still known as "Okietown".
