Based on the original by Spencer R., and the ldd file from Rocco B. I ended up modifying the structural interior a bit to add a little stability, but its mostly the same. I also increaded the scale to be proportionate to my Sears Tower. Well over 500 rare 1x2 clear tiles were used.
About this creation
After increasing the length of the base, I realized it was a bit longer than I needed, so the Wabash bridge should probably be included to the left of the tower for accuracy, but I thought it would take away from the aesthetics of the rest of the model.
Re-working the rooftop was a bit of a pain, but it worked out eventually.
As with the rest of my models, the "streets" were done in dark blue-gray.
