Gateway Gardens, formerly a residential complex for the US military, is now Frankfurt am Main’s newest municipal district, very close to the city’s international airport. The new district will be serviced by the city’s light-rail network. It will have its own station and part of the project is the construction of a nearly 2 kilometres long two track rail tunnel. Two tunnel-roof travellers from the Tunnel system DokaCC and a Tunnel formwork traveller SL-1 were part of the equipment supplied by Doka for the cut-and-cover tunnel in the Lot 2 section of the project.
