[#DYWIDAGInNorway] DYWIDAG delivers and installs the longest parallel strand stay cables in Norway to date 📏🔝 🏞️ The new Grenland Bridge across the Frierfjord in #Norway marks a key step in expanding the E18 Rugtvedt–Langangen corridor into a modern, four‑lane highway. Built parallel to the pre‑existing structure, the new single‑pylon cable‑stayed bridge features a 330m main span, a total length of 604 m, and an H‑shaped pylon rising more than 166m in height. The deck combines a steel box girder and a steel composite box girder to meet today’s infrastructure demands. The bridge also features the longest parallel strand stay cables in Norway. To ensure performance in harsh conditions, the cables are equipped with a passive de‑icing system designed to reduce ice accretion during cold weather, enhancing overall safety on the bridge ❄️ Project at a glance: #DYWIDAG was entrusted with the delivery and installation of the complete stay cable system, as-well-as the tie back tendon solution required to stabilize the deviators anchored into the surrounding rock near the tunnel portal. 🔧 👉 Project conditions introduced several challenges: cold weather conditions, a strict project time line, limited workspace on the bridge deck, and space restrictions near the tunnel portal added further complexity, especially for handling the ~320m long stay cable components. 👥 DYWIDAG successfully advanced the project by adapting installation methods, coordinating work around the limited workspace, and sequencing critical activities to keep the bridge construction on track. This ensured both the tie‑back system and the stay cable installation could be executed safely and efficiently under the site’s conditions. ℹ️ With the stay cables installed, both bridge sections connected, and stressing completed, the project has reached a major structural milestone. The bridge is not yet complete, and the next step will be damping measurements with dampers installed, including comparison tests with disengaged dampers to verify cable behavior under operational conditions.📌 As the project moves toward completion, DYWIDAG remains committed to delivering the precision, reliability, and engineered performance required for this landmark bridge all the way through to its planned opening in summer 2026. A warm thank-you to our key stakeholders EIFFAGE Norge, SYSTRA and AFRY for their collaboration and commitment which were essential to this project.
