22-Aug-10 – (Left) A helicopter has just flown through the raised bridges at Michigan Avenue, Wabash Avenue, and State Street, and is seen here starting to turn around directly in front of Marina City on Saturday morning. The bridges were raised simultaneously shortly after 9 a.m.

From a camera mounted in front, crewmembers in the back seat of the helicopter are filming the riverfront for the Transformers 3 movie being made in Chicago.
