The subsequent 2.0 km section with the construction of the Randersacker Main Bridge and the extension of the Randersacker junction was started in 2007 and completed in July 2011. The six-lane traffic release took place together with the eastern adjacent section. In Fahrtrichtung Würzburg wurde im Steigungsbereich des Spessartaufstiegs ein zusätzlicher vierter Fahrstreifen errichtet. The last part of the track construction is long and ends at the intersection Biebelried. From June 2007 to December 2009, the early, partial conversion of the junction Rottendorf was carried out. The start of construction for the actual expansion was in the fall of 2009.
