Transformers 3 Filming: Epic Explosion

From my view down Wacker Dr. Transformers 3 filming in front of Hotel 71, an epic explosion. Sound is muted after 15 second mark. The streets and bridges surrounding the set were closed off. This happened at about 6:30PM. They had been setting up and practicing camera movements for a good hour or two beforehand. I was very fortunate.
