In order to improve the traffic flow in the south of Graz, a section will be expanded to four lanes between the Puntigamer bridge and the Liebenauer belt. The 2 km long junction will be applied as a double-tube subsurface route (about 1.4 km) and connected through two roundabouts in Puntigam and Liebenau.
