From height Keilberg the route was moved with the Kauppenbrücke for reasons of noise protection from Waldaschaff away to the south. The 30 km long middle subsection, for which the Autobahndirektion Nordbayern in 2016 stated construction costs of 287 million euros, lies between the Kauppenbrücke and the Mainbrücke Bettingen. The 7.7 km long route to the junction Rohrbrunn was expanded since April 2013 and released on 17 November 2015 for traffic. In the direction of Würzburg, an additional fourth lane was built on the slope of the Spessart climb. The approximately five-kilometer-long route between the Rohrbrunn junction and the Haseltalbrücke (including the expansion of the Spessart Süd refueling facility) has been under construction since 2016. The construction period should be around four years and be completed in 2018. Here, the connection point is moved out of the T + R Spessart. Between 2007 and May 2012, the replacement new construction of the Haseltal bridge was erected and, in addition, two 1.2 km-long sections of the adjacent planning sections were extended on both sides of the bridge. For the following approximately -kilometer-long section to the west of Marktheidenfeld, the plan approval decision has been available since July 2008. The expansion started in 2016 and will take four years, to be completed by 2020. The plan approval decision has been in place since October 2008 for the section to the Main; the expansion began in 2014 and was expected to be completed in 2017. The adjoining Mainbrücke Bettingen was previously completed in 2001 after three and a half years of construction. The bridge is passable, but until the 6-lane completion of the adjacent sections, provisionally only four lanes are open. The eastern subsection, for which the Autobahndirektion Nordbayern 2016 construction costs of 574 million euros stated, lies between the Main Bridge Bettingen and the intersection Biebelried. It consisted of seven planned parts. The first included a 6.5 km section of track, which began east of the Main Bridge Bettingen and was in Baden-Württemberg. Construction work began in 2014 after the planning approval decision in 2007 and was completed by the end of 2017. A two kilometers after the border beginning eleven-kilometer section to the interchange Würzburg-West was extended between June 2009 and December 2011. The expansion of the 8.0
