First, while the depot was closed and effectively abandoned in 1986 when Metra moved to the roundhouse site (Amtrak having previously moved to Naperville), it was only demolished after part of the cornice fell onto Broadway sometime post-2010 (I forget the exact year).
Second, keep in mind that nothing here is on a due north-south or east-west alignment. Broadway is technically a n-s street and Clark e-w, but they are off from the cardinal directions by at least 30 degrees. The tracks go through on an angle of close to 45 degrees, northeast to southwest.
Clark seems like it's pretty far from the depot to have had a tunnel extending to it. I never explored the area when it was all still open, but I my understanding is that the entrance to the underpass to the platform stairs was outside the depot itself.
Okay, I just checked the Bing Maps street view, which is old enough to show the depot still standing. It appears that there was just a sidewalk along the southeast side of the tracks to just south of the corner of Broadway and Clark, where (as a train goes east) the embankment changes to the viaduct that carries the tracks to New York St. (okay, there is a short section of fill between Clark and Benton).

In the past I've ask for much information and help on the Aurora Depot, that was in placed from the Early 30's through it's eventual demolition in 1986, after being moved to the current location in Aurora. Thank you to all those that answered.
There is one question that I haven't asked, and I don't have my CB&Q materials handy is to see if it covered, but was access to platforms 1 and 2, between tracks 2 and 3, done via the underpass that ran North / South under the tracks from the Depot itself on the south side off South Broadway, to the north side of the tracks, and up stairs. Was there an underpass running under the tracks, from this pedestrian underpass to the East on Clark street?
