The Western Hills Viaduct, looking east from Hiawatha and Ernst Streets in South Fairmount. Completed in 1932, the Western Hills Viaduct replaced the Harrison Avenue Viaduct to the south, routing streetcars along the bottom deck. The arch in the foreground spans Mill Creek. The arch in the distance (over the No Parking sign) spans Spring Grove Avenue. There was also a C&O rail yard directly behind the vantage point of this photograph.
