Henderson Waves (亨德森波浪桥)) is a 274-metre (899 ft) long pedestrian bridge. At 36 metres (118 ft) above Henderson Road, it is the highest pedestrian bridge in Singapore. It connects Mount Faber Park and Telok Blangah Hill Park. It was designed by IJP Corporation, London, and RSP Architects Planners and Engineers (PTE) ltd Singapore.

The bridge has a wave-form made up of seven undulating curved steel ribs that alternately rise over and under its deck. The curved ribs form alcoves that function as shelters with seats within. Slats of yellow balau wood, an all-weather timber found in Southeast Asia, are used in the decking. The wave-forms are lit with LED lamps at night from 7pm to 2am daily.

Description
Henderson Waves springs from a scenic location off Mount Faber and spans some 284 meters above Henderson Road, a six-lane freeway running through the south coast of the island state. This man-made structure, the largest of its kind in Southeast Asia, is smoothly integrated into the landscape.
It has seven spans, six of typical size (3.5 meters high, 24 meters long), and a larger one (6 meters high, 57 meters long). The upside spans unfold above deck level and house temporary activities, such as seating, lounging and sight-seeing. The remaining spans unfold below deck level and are not accessible –simply ensuring the continuity of the structure.
Two inclined decks extend the bridge at both ends, linking it with existing pathways and plazas. The full length of the bridge runs close to 284 meters, and the difference in elevation between springing and landing is equal to the full height of a seven-story housing block.
The design concept of Henderson Waves is based on a folded three-dimensional surface-form created by means of simple mathematics. The architect of the project used proprietary mathematical techniques to define its form simply and rigorously. Hence the form bends, undulates, and ascends by twenty-one meters in one movement; in the process it also deforms to provide adequate egress, sloping, shelter, and scenic viewing to pedestrians and cyclists.

Materials
The surface-form of Henderson Waves is made of steel and timber. Steel is needed for structural purposes, whereas timber celebrates the beauty of natural forms.

Steel
The primary structure of the bridge features a sequence of steel arches and catenaries (or down-facing arches) joined across, and resting upon, reinforced concrete pylons. These pylons (the tallest of which reaches 38m) sit between waves as it were, at the point where the surface-form self-intersects and tapers down to a single beam.
