S21 – Access Walkways

A number of architectural alterations are being made to the state capital of Stuttgart as part of the Stuttgart 21 railway project. These changes include the construction of a new, underground, eight-track through station with a train shed that measures approximately 447 metres long and 80 metres wide.

Bridging Distances – Access to the New Stuttgart Underground Station

Three walkways allow passengers to access the new train shed from Stuttgart’s historic Bonatz building. These walkways consist of bridge-like reinforced concrete composite constructions with stairs leading down to the platforms. From a structural planning perspective, it is possible to split the walkways into two separate sections: a reinforced concrete composite section and a classic reinforced concrete section with infill panels made from precast reinforced concrete elements.
