Wabash Bridge Station in East Hannibal, Illinois; October 1922. railroad tracks on the left.

Notice the milk cans in front of the station waiting to be picked up.

To the right of the station is the auto "highway", which also crossed the bridge. This was the path of three highways: the Pikes Peak Ocean to Ocean Highway (later to become US Route 36); the Cannonball Trail; and the Big Four Trail.

Notice the highway marker on the telegraph pole at right — it is for the Big Four Trail, which was designated by a sign with three bands: yellow, black, yellow. Before modern highway signs, each highway had its own distinctive markers which were tacked up on telephone poles, trees or painted on the sides of barns.
