Design Concept

The bridge features a curved structural profile that ensures efficiency and a distinctive visual identity within the river corridor, with all functional components integrated into the 7-meter-wide deck. Wooden seating creates localized rest areas, while the epoxy resin-bound surface provides durability and low maintenance. Safety is ensured through an anti-vandalism climbing-deterrent system and handrails with low-energy LED lighting, offering pedestrian security while minimizing ecological impact on the river.

Structure and Engineering

The structure is designed as a 66-meter single-span system, utilizing a hybrid steel truss construction. This configuration eliminates the need for any piers within the Iller River floodplain.

• Load Path: The truss is composed of an arched upper chord and a reinforced lower chord (deck), with bracing provided by circular hollow sections.
• Deck Support: The deck is mounted on elastomeric bearings and incorporates expansion joints to accommodate thermal movement.
• Assembly Method: Construction relies on significant off-site prefabrication of large sections, followed by transport and on-site assembly via crane, minimizing the duration of work within the sensitive river environment and accelerating the 12-month construction timeline.

Sustainability (Regeneration/Resilience)

The sustainability strategy emphasizes resource efficiency and material longevity, aligning with current life cycle assessment goals.

• Resilience: The single-span typology inherently minimizes the structural footprint and contact with the floodplain ecosystem, ensuring resilience during high-water events.
• Material Strategy: The project specifies the use of recycled materials and explores the integration of low-carbon alternatives, including fossil-free steel and low-carbon concrete.
• Durability: Longevity is ensured by applying durable fluorocarbon protective coatings to the steel and using a low-maintenance deck surface. The integrated LED lighting system is designed to be highly energy efficient.

Urban Integration and Spatial Experience

The bridge provides critical, dedicated infrastructure for non-motorized transport (NMT), directly linking separated urban sectors. The 7-meter width and integrated seating elements transform the structure from a purely functional route into a linear public space, effectively supporting localized social exchange and breaks in the pedestrian and cyclist flow. This strategic infrastructure investment enhances city-wide connectivity and defines a key reference point in the local urban fabric.
