Highway 90 is a study of a key roadway that traverses Louisiana from Mississippi to Texas, but has origins to the East in Florida and to the West in Texas and beyond. The roadway was built in the 1930’s following the elevated areas along the Gulf Coast. The path chosen was parallel to the Southern Pacifc Road road built in the 1880’s. Later, the same general path was selected when the Interstate 10 was constructed in the 1960’s. These three transportation facilities played a significant role in the development and location of population centers along the Coast. The path of roadway is plotted on existing soil types and ecological zones and compared to the distribution of population density.
