On this page of our game guide to Batman: Arkham Knight we have prepared a detailed description of the Escape from ACE Chemicals. A batmobile will be helpful in the execution of this plan. You will have to use the remote control feature, the winch and the nitro afterburner.
After taking control over Batman again, activate Batmobile Remote Control. Switch to Battle Mode and use the Winch on the interactive object on one of the walls. Reverse and wait until the wall is destroyed. Get inside the Batmobile. Now you need to leave the factory - follow the road and don't forget to use the Afterburner when you're outside. This will allow you to jump across the broken part of the bridge.
Note - From now on, you can see the location of Augmented Reality challenges on your map. Completing is not required to finish the main story.
