Update: The tunnel was completely filled in by the winter of 2013. See construction photos from July of 2010.
The Tucker Tunnel is one of those places in St. Louis that older residents might remember, but as the city progresses, fewer and fewer people remember its existence. It has been in the news more lately, as the city has had to shut down several lanes of Tucker Blvd up above the tunnel because it’s starting to collapse. It used to provide access for a passenger railroad that went to Alton. Also, the Post-Dispatch used to have its paper delivered down in the tunnel; you can still see the loading dock for the newspaper in the tunnel. Also evident are the supports that have hopefully temporarily been put in place to support the road deck up above. Basically the tunnel is a cut and cover design; in a way, all of Tucker through much of downtown sits on top of one long viaduct or bridge.
