A major infrastructure project for northwest Germany
The Weser crossing as part of the A 281 autobahn is currently taking shape as one of Germany’s most challenging tunnel construction projects. The structure will close the final gap in Bremen’s motorway ring road between the A 1 and the A 27, significantly improving transport links across the region. The tunnel sections are being built using the cut-and-cover method on both banks of the Weser, and we’re pleased to support our customer Wayss & Freytag on this major project with customised formwork and shoring solutions.
A particular highlight is the two 10-metre-long tunnel formwork carriages developed by Hünnebeck. Built from INFRA-KIT system components, these carriages make it possible to construct large tunnel sections with a high degree of precision, safety and efficiency. Equipped with heavy-duty rollers, the carriage is hydraulically lowered and raised by remote control, then moved to the next concreting section with the help of wheel loaders — creating ideal conditions for an economical construction process. The tunnel walls and roof are anchor-free, and the central wall serves as a guide wall. INFRA-KIT walers are resistant to the fresh-concrete pressure across the entire superstructure cross-section.
Hünnebeck systems are also being used to construct the trough section, including the 565-metre protective gallery. MANTO wall formwork combined with the INFRA-KIT modular system is being used for the external walls, while ES 24 and shoring frames are being used for the interior wall formwork. GASS shoring towers, INFRA-KIT, large-area H20 formwork and PROTECTO fall protection support the safe and efficient construction of the protective gallery’s downstand beams.
Projects like this show how innovative formwork technology and engineering expertise help deliver complex infrastructure projects successfully. A heartfelt thank-you to Wayss & Freytag for the trusted, collaborative partnership!
