As we continue along, we start to loose natural light and the area
becomes like a man-made cave. Since we're probably under Marina
City, this area was once part of the CNW's state street yard.
We're under the House of Blues now, and that's a performer's bus.
Note ladder track configuration.
Approaching Clark Street, the tracks are in good shape thanks to
the Quaker Building (we're under it now) construction in the 80's.
Now that we're out of the tunnel, lets take a step out to get a
better idea of where we came from.
Looking farthest to closest, that's the IBM building, Marina City
Towers, House of Blues, and in front of us, the Quaker Building.
Under the Clark Street overpass, we can make out the message "YOU
WILL BE TOWED RAILROAD IN USE STAY CLEAR OF TRACK".
Looking back towards Clark Street and the Quaker Building, the tracks are older here as evidenced by the timber guard construction.
That's the LaSalle Street overpass.
The building beween the Merchandise Mart/Wells street and LaSalle street are the only older buildings along the Navy Pier Line. Note the loading docks, as there once was a spur that served these buildings.
Under the BMW the sinking asphalt gives clues to the track configuration. Using the maps in the Research section, you can get a better idea of how this area looked.
