The future noise protection structure is part of the extension of the A7 highway in Hamburg and Schleswig-Holstein. Tunnel Stellingen is roughly 1km long. With Hochtief as technical leader, the joint venture will construct two cut-and-cover tunnel tubes with five lanes each and one emergency lane. The tunnel is one of three noise protection tunnels, the "Hamburger Deckel", which will be built within the framework of the expansion project.
"We are delighted to be able to bring in our execution competence into a further section of the A7. With this noise protection program, we offer the citizens of Hamburg better quality of life in the future", said Nikolaus Graf von Matuschka, CEO of Hochtief Solutions.
