The joint venture A 1 Lohne Bramsche kicked off 2021 with the acquisition of a large project in transportation infrastructures. The Federal Republic of Germany, represented by Die Autobahn GmbH des Bundes, Westphalia Office, commissioned a joint venture consisting of STRABAG AG 50 % and JOHANN BUNTE Bauunternehmung GmbH & Co. KG 50 % with the widening of the A1 motorway in Lower Saxony over a distance of around 29.5 km under a so-called function based construction contract FBV.
The section, located between the Lohne/Dinklage exit and Bramsche exit, will be widened from two to three lanes in each direction. The approx. EUR 600 million contract also includes structural maintenance over a period of 30 years.
JOHANN BUNTE will take the technical lead and STRABAG the commercial lead in the joint venture. Construction will start on 1 February 2021 and will be carried out under traffic. Completion of the motorway section is scheduled for mid-2025.
In addition to extensive earthworks and the construction of the carriageways, 14 bridges along the motorway section as well as two overpasses over the motorway must be completely rebuilt. In addition, 18 bridges will be rehabilitated. The joint venture will also perform noise barrier works as well as accompanying landscaping. With the aim of affecting the traffic flow as little as possible, the joint venture will carry out its activities in eight construction phases. In the first five phases, the motorway is to be widened in the direction of Osnabrück (2021 and 2022). Once these works are completed, the next three phases foresee widening and new construction works in the direction of Bremen.
