The OpenDRIVE datasets of two sections of the German Autobahn A9 were originally provided by the MDM Portal as open data. However, since the migration to the new Mobilithek, the download of the respective files no longer works.
As they are licensed under Nutzungsbestimmungen für die Bereitstellung von Geodaten des Bundes and in order to ensure their continued usability, they are made available in this repository as an interim solution.
