In the 1930s railroads were still important in transporting people, but increased automobile ownership led to a demand for paved roads and highways. Many of the highways on the map are by name only such as "Old Spanish Trail" and "Puget Sound to Gulf Hwy". The index on the right side lists "Cities and Towns with population over 1250". This great reproduction is an excellent resource for historians and will make an interesting conversation piece in any room.
