However, in March 2008 the Federal Ministry of Transport approved an early start of planning. The plan approval procedure was initiated on 25 August 2014. Now it is considered to expand the 120 kilometers between Regensburg and Passau completely six-lane. The cost of this is estimated at 1.2 billion euros. In the Federal Transport Infrastructure Plan 2030, the sections between Nittendorf and Rosenhof as well as between Deggendorf and Hengersberg were finally classified as Priority Needs, the section between Hengersberg and Aicha vorm Wald into further demand with planning rights. For the remaining sections, there is currently no extension due to a low cost-benefit ratio.
