Construction of the A66 bridge's second segment, located near Wiesbaden, has been completed, with an opening date set for August 1, 2025.
=========================================================================================================
The Salzbachtal Bridge, a crucial highway viaduct in Wiesbaden, Germany, has undergone a dramatic transformation over the past decade. Its tale is one of impressive engineering, resilience, and a remarkable comeback from a tragic collapse.
Key Events Timeline
Construction and Initial Opening
- The bridge was completed and opened to traffic in 1962, with a second parallel structure added in 2006 to accommodate increased traffic volumes.
- On March 11, 2010, the newer (western) section of the bridge suffered a dramatic collapse during maintenance work, while the older (eastern) section remained intact.
- The collapsed section was demolished, and the intact eastern section was maintained for limited, restricted traffic.
Reconstruction Phases
Western Section (Collapsed 2010)
- The new western bridge section was completed in 2016, featuring a modern, corrosion-resistant steel box girder design.
- The new western section opened on October 28, 2016.
Eastern Section (Original 1962 Structure)
- Due to safety concerns, the eastern side (from 1962) was monitored and temporarily reinforced, remaining in service but with strict weight and lane restrictions.
- Planning for the replacement of the aging eastern bridge began in 2017, with construction starting in 2019 and completion targeted for 2024.
Costs
- The collapse caused considerable economic disruption, but direct costs from the collapse itself were relatively limited compared to reconstruction.
- The new construction cost for the western section was approximately €45 million.
- The replacement of the eastern section is estimated to cost around €96 million.
Technical & Engineering Overview
- The 2010 collapse was triggered by a failure in the temporary support system during renovation of the bridge’s expansion joints.
- The replacement structures feature improved materials and construction techniques to prevent corrosion and enhance longevity.
- Between 2010 and 2016, traffic was severely restricted, with long detours affecting both commuters and freight.
Summary Table
| Section | Original Completion | Collapse/Restriction | Reconstruction | Reopening | Estimated Cost | |----------------------|------------------------|--------------------------|--------------------|-------------------|------------------------| | Western (original) | 2006 | Mar 2010 (collapsed) | 2012–2016 | Oct 28, 2016 | €45 million | | Eastern (original) | 1962 | Restr. after 2010 | 2019–2024 (planned) | Expected 2024 | €96 million (est.) |
Conclusion
The Salzbachtal Bridge project is a multi-year, multi-million-euro endeavor that transformed a tragic infrastructure failure into a showcase of modern German engineering resilience. The western section was completed and reopened in 2016, while the eastern section is still under reconstruction as of mid-2023, with an expected reopening in 2024. Together, both projects represent a total investment approaching €140 million.
