The city saw exponential growth in the early twentieth century with the production of lumber and the manufacturing of furniture. By 1920, Evansville had more than two dozen furniture companies. In the decades of the 1920s and 1930s, city leaders attempted to improve Evansville's transportation position and successfully lobbied to be on the Chicago-to-Miami "Dixie Bee Highway" (U.S. Highway 41). A bridge was built across the Ohio River in 1932 and in that same decade steps were taken to develop an airport.
