The central check-in terminal is located between the two runways and thus above the ICE track and the motorway.
Access of the check-in building is via the curbside level between building level and rail level, which is also usedby the airport as north-south connection and which also provides direct access to the ICE railway station.
The building is characterised by its roof in which shed-like s kylights have been created by alternating roof height although the girders are of the same length.
After check-in has been completed, passengers enter the mall to proceed (tothe north or the south) to their aircraft. The western part of the mall accommodates facilities such as shops, travel agencies and restaurants.
The eastern section of the mall is characterised by a large glass front which creates a relation with the landscape outside. Another important feature of the mall is its uniform, ellipse-segment-like cross section which has been maintained over the mall's entire length of almost 300 metres.
