Strengthening Suurhoff bridge with innovations in bridge renovation

We developed and implemented an innovative strengthening method involving steel plates, epoxy, and pre-tensioned injection bolts. Arup’s experts seamlessly integrated these prefabricated units with the existing deck, ensuring the bridge remained open during the four-week renovation.

The Suurhoff bridge is vital to Rotterdam’s port operations. With strengthened infrastructure and enhanced safety measures, the bridge continues to facilitate seamless connectivity between key industrial hubs. The applied innovation reduces future maintenance operations which is beneficial from a cost and hindrance perspective.

Innovation in bridge renovation

Faced with aging infrastructure and growing traffic demands, the Suurhoff Bridge needed a resilient solution to ensure continued use. Traditional strengthening methods for the steel, orthotropic bridge deck were not feasible due to weight and time constraints. Drawing on lessons from previous projects, the team adopted steel strengthening plates and advanced engineering techniques to extend the bridge’s life, minimize maintenance, and reduce traffic disruption, securing Rotterdam’s industrial connectivity. 

Collaboration is key to success

The project's success lies in its thorough design and close collaboration with Rijkswaterstaat, contractors and research institutions. 
    
Prefabricated steel plates were welded together and connected to the existing steel deck using epoxy and pre-tensioned injection bolts. This addition reduced fatigue in the existing welds, thereby extending the structure’s lifespan. Special attention was given to details, such as drilling precise bolt holes and managing welding deformations. Complex modeling and thorough preparation ensured the effectiveness of each structural element, guaranteeing the bridge’s long-term durability.

From inception to completion, every aspect of the project was thoroughly coordinated. Strong collaboration between Arup and project partners Takke Breukelen, Hollandia Services, TNO and TU Delft ensured minimal disruption and efficient execution. 

The bridge remained partially open to traffic throughout the four-week renovation period, showcasing a remarkable feat of engineering amidst operational challenges.
