I have more photos of Transformers 3 filming in Chicago.

You’ve probably seen “No Parking – Parade Route – Police Order” signs directed at motorists.

But check out this sign: It informs bicyclists that because of filming on this block, their bike could get in the way and would be removed. So everyone should be gone by 6 PM on Friday.

Michael Bay’s Transformers 3 started filming in Chicago two weeks ago. Additional filming will take place this weekend on part of LaSalle Street. The Chicago Film Office put up these signs (with CDOT’s cooperation) to alert bike riders that they should not leave their bikes here over the weekend. When robots run around, things get messy!
