The B&O line crossing over Duck Creek Road in Norwood, looking north. As serene as this view looks, I-71 is just 100' off to the right. The US Playing Card Company is behind and to the left. Some maps mark this road as Harris Avenue, but it is basically a back entrance to the old US Playing Card Company factory. The exact date of the tunnel is unknown, but it's probably no newer than the 1880s. It could date to the original 1860/1861 construction of the line through here, but with no cornerstone it's anybody's guess about its exact age.
