Bridge, as a special building typology, has long been a special existence. If traffic connection is seen as its basic attribute, spatiality, landmark and cultural symbol may form other important attributes in terms of aesthetics for the existence of bridge, either as a physical entity or a space. Therefore, how to create a new visual and traffic experience at the specific site of Pingshan River became the starting point of and challenge for our design of this pedestrian bridge.
Based on the relations between the main entrance of the school and Zhenhuan Road, we proposed four conceptual design options with different site locations. These proposals were expected to candidly showcase the consistency of architectural form and structure; meanwhile, they also attempted to interpret the traditional Hakka culture in a contemporary context, which served as the beginning point of the design.
The bridge spans 70 m over the Pingshan River. Its elevation design gives priority to the relation between the bridge deck and the surrounding environment. The starting point of the bridge on the north bank should be at least 5 m away from the cycling lane in front of the school gate to minimize the impact on traffic circulation at the school entrance. The main structure of the bridge deck should be higher than the once-in-a-century flood level and avoid the existing sewage interceptor well. While ensuring barrier-free access, the bridge deck should also be smoothly connected with the landscaped footpaths on the north and south banks that both show a height difference of about 1 m. The clear height below the bridge ensures comfortable pedestrian experience of the Grade II waterfront footpaths. To shelter pedestrians from the hot and rainy weather – typical of South China, the bridge is covered with a linear roof, which, in contrast with the varied height of the deck, contributes to a concise, calm yet solid presence of the bridge.
