How well did you find your way around 1948 Chicago?
One block to the east, at Keeler, a railroad viaduct still crosses Irving Park. But that viaduct has been replaced, and the Chicago & North Western has also been been replaced, by the Union Pacific and Metra. Beyond the railroad, an elevated viaduct carrying the Kennedy Expressway has also been constructed.
The clues are the wide street and the dual overhead wires for trolley busses, which will soon replace streetcars on Irving Park.
