Successfully renovating instead of replacing: concrete Mark Bridge extended by 30 years
The renovation of the Mark Bridge between Moerdijk and Halderberge highlights the importance of sustainable infrastructure lifespan extension. By opting for renovation instead of full replacement, costs, material usage, and CO2 emissions were significantly reduced. By using innovative techniques and repairing damaged concrete instead of replacing it, about 150,000 kg of CO2 emissions were avoided. Keeping the bridge partially open during the works avoided additional traffic disruption and emissions from diversions, aligning with the vision to maintain concrete structures for at least 80 years.
Collaboration within a project team including BAM, Nebest, and SealteQ was essential in identifying sustainable solutions. Sharing knowledge and expertise enabled the project to be delivered in a technically, socially, and environmentally responsible manner. The renovation demonstrates that material reuse and efficient environmental management support a sustainable and circular infrastructure. This approach received recognition with the 2023 Cobouw Award and a nomination for the 2024 Concrete Award, setting an example for future infrastructural challenges.
