Zaha Hadid Architects has revealed the Grand Canal Gateway Bridge, a striking curved footbridge in Hangzhou, China, that features three white arches weaving around the structure's walkways. The bridge is set to open to the public later this year and serves as the centerpiece of the ambitious Seamless City masterplan, which includes residential areas, parks, civic buildings, and commercial districts, all designed by the renowned UK-based architectural firm.

The bridge's unique design draws inspiration from Hangzhou's rich heritage in silk embroidery, a craft for which the city has been famous throughout Chinese history. The architects created three distinctive white arches that stretch both over and under the bridge structure, using what they describe as a "sinuous structural system." This steel bridge spans across China's Grand Canal, the world's oldest and longest man-made waterway, at the point where it meets the Qiantang River, which is locally famous for its "Silver Dragon" bore—a spectacular tidal phenomenon that creates towering waves.

"Drawing on the city of Hangzhou's long-established heritage as a center of excellence for China's renowned silk embroidery, the bridge's design reinterprets traditional stitching techniques," explained Zaha Hadid Architects. "Its sinuous structural system weaves, overlaps and binds to support a bridge for pedestrians and cyclists that connects the new residential, civic and commercial districts of Hangzhou's Seamless City masterplan."

The bridge's walkway consists of two curved paths that bend toward each other over a central concrete island that divides the canal's north and south waterways. At the central point, these walkways curve perpendicularly and extend in opposite directions into two piers, which are specifically designed to provide multiple vantage points for visitors to observe the surrounding landscape and the Qiantang River's impressive tidal waves. This strategic positioning allows people to safely experience what the architects call "the raw power and spectacle of the Silver Dragon's force of nature."

The construction of the Grand Canal Gateway Bridge utilized prefabricated modular elements, a design choice made to reduce construction time and minimize disruptions to the constant barge traffic that travels along the busy canal. This approach demonstrates the firm's commitment to balancing ecological sensitivity with civic ambition, ensuring that the new infrastructure enhances rather than hinders the existing transportation networks.

This latest project adds to Zaha Hadid Architects' impressive portfolio of bridge designs around the world. The firm has previously designed a vehicle and pedestrian bridge in Chengdu featuring two symmetrical steel arches, and the Danjiang Bridge in Taiwan, which is scheduled to become the world's longest single-tower, cable-stayed bridge when it opens next year. The Grand Canal Gateway Bridge represents another innovative approach to infrastructure design that combines functional engineering with artistic vision, creating a landmark that serves both practical transportation needs and cultural significance for the city of Hangzhou.
