Update: The tunnel was filled with Styrofoam blocks and rebuilt as the new Tucker Boulevard north of Washington Avenue. It has changed dramatically around the location of this photograph.

You might have heard recently about city officials closing the Tucker Blvd Bridge in downtown St. Louis. Calling the structure in question a bridge is a bit inaccurate. They’re talking about an old commuter railroad tunnel/viaduct that runs under the street as far as Washington Ave. Here is a great site with pictures.

I found the exit to the tunnel, north of O’Fallon St. I wish they could figure out some way to make this tunnel useful for MetroLink some day.
