When the Union Pacific Lane Cutoff was built in the early 1900's, they needed ways to get roads under the tracks. Since the fills were basically long trestles, they built concrete tunnels. One that was particularly hated as the vehicles got bigger, was the tunnel at 84th St. I thought I had a picture in my collection but I don't. I got a couple of pics from the county archives. The B&W's are from 1972. The color are from the 80's when a bridge was put in and the tunnel removed. I like the one with the N&W locos on the new bridge.
