part of the revenue from the resulting truck toll. How high this share is subject to secrecy. [39] The official start of construction took place in November 2008. In the course of this expansion, the whispering asphalt in the first quarter of 2010 replaced on a refurbished and only three months released section of Bremen from a large area. When the large number of potholes no longer permitted orderly operation, the old carriageway was put back into service as a last resort. If the operator company, which only has a deposit of 10,000 euros, is in financial difficulties due to repeated construction defects, misjudgments of costs or other problems, the federal government will pay for the costs. The traffic researcher Michael Schreckenberg criticized that the construction site sections were "made by technocrats," "without regard to the psychology of motorists."

The number of fatal accidents in the section increased from two (2008) to six (2009). In the first half of 2010, seven fatal accidents occurred. To avoid further accidents, it was decided to widen the construction site by one meter. However, since this is not regulated in the contract with the operator consortium, it has been funded with tax credits by the federal government. The expansion was completed on 11 October 2012.

Already shortly after the beginning of the work, the operating company A1 got into financial difficulties on the move, which were not made public by a standstill agreement with the financing banks. At the end of August 2017, A1 mobil sued the Confederation for payment of 640 million euros. The reason stated was that the financial crisis caused freight traffic to collapse unpredictably.
