Echterhoff Express Bridge: sustainable construction method for the future in the field of transport infrastructure
The foreword introduces the innovative construction method used for the Echterhoff Express Bridge, a modular system for the rapid replacement of bridge structures while traffic continues to flow. Prefabricated component parts, standardized interfaces, and optimized processes drastically reduce construction times and minimize both traffic and environmental disruption. In 25 completed projects, time savings of up to 75% and significant CO₂ reductions have been demonstrated. The system is flexible in its application and covers various types of structures, foundations, and superstructures. Industrial prefabrication increases the quality of execution and reduces the need for full and partial closures.
The current situation is characterized by aging infrastructure and a growing need for bridge replacements, particularly due to increased traffic loads and weather-related damage. The Echterhoff Express Bridge addresses these challenges through significant reductions in construction time, standardization, and high structural quality. A central element is the hybrid cap, which, as part of the modular system, performs several functions during the construction phase and avoids additional closures.
The system relies on the prefabrication of almost all vertical components as precast reinforced concrete elements, which shifts up to 80% of the time-consuming work from the construction site to the production facility. This enables high surface quality and resistance of the components. The system is suitable for use in around 80% of all bridge structures in Germany and already meets future requirements for sustainability and life cycle assessment.
In view of demographic change and the shortage of skilled workers, the need for new procurement models and efficient construction processes is being emphasized. The Echterhoff Express Bridge is an example of sustainable and resilient construction practice in the infrastructure sector.
