sculptural infrastructure planned for bangkok
The Bangkok Metropolitan Administration unveils visualizations of a proposed pedestrian bridge across Thailand‘s Chao Phraya River. Located between existing vehicular crossings, the structure will introduce a dedicated thoroughfare for foot traffic and cyclists. A lattice of gold-toned metal defines the sculptural architectural form, making use of a diagonal grid that wraps around the walkway to create a semi-enclosed volume.
The span swells at the river’s center to accommodate a landscaped public plaza where stepped terraces break the linear circulation path. Timber platforms integrate with the steel framework to provide seating, while planters containing tropical flora sit between the tiered levels. This open design exposes the water surface below to maintain a visual connection to the tide.

a proposed bridge dedicated to pedestrians
There are few bridges in Bangkok designed exclusively for pedestrians, making this link between the historic Phra Nakhon district and the residential district of Thonburi a major addition to the city grid. The alignment runs parallel to the Memorial Bridge to offer an alternative to the ferry system for those crossing the water on foot.
Ramps and staircases connect the elevated deck to the riverside promenades, ensuring these access points merge into the existing street layout. The paving material continues from the land onto the pedestrian bridge to signal a continuous path for commuters. The distinct golden color of the structure provides a sharp contrast against the concrete and asphalt of the surrounding urban environment.

a structure of intricate latticework
The intricate lattice functions as a passive shading device, with the density of the metal weave varying along the length of the bridge to respond to solar orientation. Tighter sections filter the intense tropical sunlight while the porous grid admits constant breezes from the river surface. Lighting fixtures remain hidden, embedded within the intersections of the steel beams to illuminate the walkway at night.
Structural clearance dictates the height of the deck, as the elevation must accommodate the passage of express boats and heavy cargo barges. Massive concrete piers support the span from the riverbed, positioned to withstand the pressure of the water. These vertical supports align with the flow of the current to minimize turbulence around the base.
