June McCarroll

• abstract: June Hill Robertson McCarroll (June 30, 1867—March 30, 1954) was a nurse (later a physician) with the Southern Pacific Railroad in the early twentieth century who is credited by Caltrans with the simple but revolutionary idea of delineating highways with a painted line to separate lanes of traffic. The concept of painting lines to separate lanes is now in use all over the world.
