| Hochtief to build A7 Tunnel in Hamburg-Stellingen Hochtief Infrastructure together with Franki Grundbau has been awarded the contract to construct Tunnel Stellingen in Hamburg. The total contract volume for the joint venture amounts to approximately EUR 154 million. The future noise protection structure is part of the extension of the A7 highway in Hamburg and Schleswig-Holstein. Tunnel Stellingen is roughly one kilometer 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. Hochtief had already achieved financial close for planning, financing, expanding, operating and maintaining the A7 section from Neumünster-Nord to Hamburg-Nordwest as early as August 2014. In addition, Hochtief is also building the Langenfeld bridge on the A7 in Hamburg-Stellingen. write your comments about the article :: © 2016 Construction News :: home page |
