As leading member of a consortium, Schüßler-Plan was awarded the major contract for the design of the A26 East in mid-July 2015. The complex traffic infrastructure project, which was put out to tender throughout Europe, is executed on by order of DEGES.

The continuation of the A26 will close a gap in the trunk road network in the south of Hamburg, connect the internationally important traffic arteries of the A1 and A7, significantly improve accessibility to the Port of Hamburg and divert supreregional traffic from the Hanseatic city.

The new section is divided into four traffic units of which the "ARGE A26-East" consortium is designing a 4.1 km long section running from the HH-Hohe Schaar autobahn exit via the Harburg junction to the HH-Stillhorn autobahn interchange. The design includes a 2.2 km long overpass south of the Süderelbe crossing, tunnels and trough structures as well as about 20 bridges. In addition to traffic planning, the commissioned planning scope includes the design of facilities and structures for civil engineering structures, the design of noise protection facilities and technical equipment and traffic engineering services.
