On August 14 the American Association of State Highway Officials adopted a design for interstate highway markers, as well as a system for numbering individual highways in the interstate system. The markers were to be a red, white, and blue reflectorized shield with the legend "Interstate," the name of the state, and the route number. The numbering system was not to use more than two digits. North-south routes were to have odd numbers beginning on the west coast and going east, and east-west routes were to have even numbers and start in the south.
