Abstract :
One of the most perfectly lighted stretch of automobile road in the world is located upon the Lincoln Highway a few miles south of Chicago. Twenty-eight concrete standards, spaced 250 ft. apart, each carrying a 250-c. p. electric lamp, equipped with a reflector which throws the light evenly upon the road bed but not beyond it, constitute the lighting equipment of this ideal section of the famous highway. During the course of a year these electric lamps are turned on by the master switch a total of 4000 hours and the yearly cost is less than 25 cents per foot of road illuminated.
