Structure and Engineering

The centerpiece Radiumbrücke is designed as a shallow-arched, single-span pedestrian and bicycle bridge that crosses the Wupper without requiring intermediate piers in the water channel.

Its structural system functions as a continuous slim beam and arch hybrid, minimizing structural depth and maximizing hydraulic clearance below. The bridge features a custom vertical steel balustrade with integrated LED accent lighting along the railing for evening safety and visual polish without light pollution.

Structurally, the bending moment strategy optimizes load distribution to transfer horizontal and vertical forces efficiently into reinforced concrete abutments.

Sustainability

Sustainability is built into both the ecological and physical infrastructure of the project.

Softened riverbanks promote local biodiversity, native riparian plant growth, and better aquatic habitats.

Sustainable drainage methods include rain gardens, permeable paving, and bioswales designed to collect and naturally filter rainwater before it reaches the Wupper.

Furthermore, large expanses of asphalt and concrete industrial parking areas were unpaved to reduce sealed surfaces and create micro-climate buffers. High-durability, low-maintenance, recyclable structural steel and timber were selected for long service life.
