Specifically the project entails a 4km link from the existing regional rail tunnel to Frankfurt Stadium, and includes the construction of a double track underpass under the B43 highway and A5 motorway north of Frankfurt Cross, and a 2km-long tunnel and an underground station at Gateway Gardens.

The total cost of the project is €223m with the State of Hessen, the City of Frankfurt, German Rail (DB), and Rhine-Main Transport Association (RMV) co-developing the project. Completion and commissioning is scheduled for 2019.
