HOCHTIEF has been awarded by DEGES the contract for construction of the complex 2.2-kilometer-long noise protection tunnel Altona on the A7 highway in Hamburg including access and exit roads. The project has a total volume of around EUR 580 million (net). HOCHTIEF will take on the technical lead and has a 65 percent share in a joint venture.
Work between the A7 junctions Othmarschen and Volkspark is expected to start in April 2021 and be completed by 2028. The Altona tunnel is the longest of the three “Hamburg lids” which are constructed by HOCHTIEF in the city area of Hamburg and contribute significantly to reducing the local residents’ noise exposure.
