Feature request title:
As an extension to the multi floor feature to have the option to build skybridges/walkways/connections between buildings that are on higher levels so vehicles and planes can drive underneath them.
Why it should be implemented:
This ads the option to connect buildings but still give vehicles and planes the option to drive in between the buildings instead of round the building. This opens the opportunity to have a taxiway in the middle and multiple stands on either side and still connect them to a building.
