The toll square is a green room in the ‘Zuid-Beveland’ polder landscape: a square bordered by poplars. The proportions of this square situated in a renaissance polder are also derived from the representative proportion of the village Borssele (golden section). Inside, toll is levied in both directions of the traffic flow, the tunnel and the toll collection booths are controlled and car pooling spaces, bus stops, bicycle sheds and spots for potential petrol stations are to be found.
A footbridge connects the functions on both sides of the road and forms a canopy above the toll collection booths; the roof folds upwards above the marshalling areas: an inviting gesture for the approaching road user.
The glass superstructure of the building on the east side, houses rooms for the control of the tunnel and the toll collection. The black basalt substructure accommodates supporting functions and a bus waiting room.
All other structures: toll booths, power supply building and bicycle shed link up with the bridge or the control building in terms of design and materials used.
