Henderson Waves, Singapore

Henderson Waves, Singapore, stands as the highest pedestrian bridge in the city at 36 metres above Henderson Road, connecting two parks along the Southern Ridges walk. Completed in 2008, its wave-form steel and timber structure — resembling a massive undulating serpent — earned the ASEAN Outstanding Engineering Achievement Award. Its seven undulating ribs each curve at a 30-degree angle, creating a rhythmic silhouette unmatched in Southeast Asia.
