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.
