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. The bridge is 45% lighter than the average cable-stayed pedestrian bridge due to its innovative use of laminated timber and steel ribs. At 274 metres long, it is 14% shorter than the Langkawi Sky Bridge, #7 on this list, but its dual function as an elevated walkway and architectural landmark delivers a unique urban ecosystem link. Its seven undulating ribs each curve at a 30-degree angle, creating a rhythmic silhouette unmatched in Southeast Asia.
