Block-girder bridge provides a fully accessible link
Pedestrian and cycle bridge in Troisdorf, DE
Description
With the new cycle and footbridge over Schwabenweg, the town of Troisdorf is creating a barrier-free link between the residential area at Europaplatz and the future multi-generational park at Sieglar Comprehensive School. The new structure replaces the previous connection, which featured steps and an unsecured crossing, and creates a safe, comfortable crossing for all user groups. The bridge is being constructed as a timber bridge in accordance with DIN 1995-2 NA and follows the recommendations for cycle facilities (ERA), in particular the maximum longitudinal gradient of less than 6 per cent. The planning is based on a feasibility study from 2020, which sets out the requirements for accessibility and urban integration. The topography, the existing route connections and the choice of an optimal structural system result in a curved layout that connects the Frieslandring with the new route through the multi-generational park. At the same time, the green spaces along the underground car park entrance are largely retained to ensure privacy and urban integration. The five-span system, designed as a slender beam bridge with four supports, blends harmoniously into its surroundings. The curved lines lend the structure a sense of lightness and prevent it from appearing too massive, particularly across medium spans.
