View of old tunnel from the construction site as seen from the Post-Dispatch building.

It was used by the Illinois Terminal Railroad because their headquarters was in that area.

Do any historians out there know what purpose this tunnel served? The only thing I can think of is that trains used the Iron Horse Trestle to get access, and deliver rolls of newsprint to the St. Louis Post-Dispatch and the former St. Louis Globe-Democrat newspaper (folded in October 1986, now on-line only). And then prior to the bridge demolition...that's when the homeless people (living underneath) got chased out.
