Gulou in China’s Jiangmen City was built on tidal flats where farmers and fishermen pushed the dirt around to form mounds and ponds. In this area, land parts were often connected by wooden bridges. Now, it is being turned into an eco-cultural tourism resort by LUO Studio. The press release states that it “maintains the form of the basic local water system, while organically integrating nature education, parent-child recreation, and fishing & husbandry activities.”
“During the fishing civilization period, roads were poorly developed, so water systems became key routes of transportation and logistics,” states LUO Studio. “Bridges needed to be walkable, while also ensuring more space for boats to pass through underneath, so traditional bridge construction techniques in China adopted ‘arches’ to create space.”
Arched bridges, sometimes called moon bridges, were high enough in the middle for barges to get under. But these bridges often had steep stairs up each side to not extend very far into the surrounding fields.
LUO Studio has designed this covered arch bridge out of wood, which was evidently common in the area. It explains:
The arches are each made of three large curved beams set about 10 feet apart, each delivered in three pieces and “connected and assembled by steel-strengthened bolts on the site, to form the complete wooden beam.”
The actual covering of the bridge is made of overlapping metal plates set eight inches apart to allow light and ventilation and, at certain levels, a view.
“When walking slowly into the corridor space from the entrances at both ends, visitors can catch the sparkling water under the bridge through the narrow gaps between steps. As they continue to climb the bridge, the bright light refracted by the upper and lower metal plates attracts them to look out through the side gaps,” states the studio. “Such a special ‘collected’ viewing experience distinguishes this timber bridge from other open bridges. While passing through the platforms from two ends to reach the center of the bridge corridor, visitors can fully experience the light and shadows from the top, feeling a sense of calmness and openness in the mind. Such design forms a continuous spatial rhythm that gradually reaches the climax.”
The three big beams were the only components that needed big machines to set:
One of the problems with arch or moon bridges is they have a lot of stairs and are not universally accessible. While these don’t seem very steep compared to some of the ancient bridges, it still is surprising that this was permitted, given that for a decade “all urban, newly-constructed, altered, and extended roads, public buildings, public transportation facilities, residential buildings, and residential communities to meet the barrier-free standards of construction work.” But then we have asked this question about pedestrian bridges in China before.
