Structures above the water going across.
Wide Building - Industrial Wide Building which displays more stairs going up and across the building.
Train Track Area - An outdoor industrial area with overhead things and old falling down walls.
Different angles of structures going upwards.
Very cool Damn - A nice damn at one side of the industrial, waves crashing up.
Type of Exit - A strange exit not just a door leading to outside, it is raised off the floor for offloading reasons from vehicles, perhaps there could be some CRATES stacked up at the bottom of this ramp
Dock with Containers - Perhaps a train track going across an empty dock with cranes of some sort (big yellow ones) going across the river on a raised platform.
Industrial Outside - A update from the other bit with train tracks outside, instead of walls it can be open like this with buildings either side.
Windows - Different style windows designed to let air in / smoke out etc.
