The Tranquil Wave is a flat bridge that gracefully melds into the background without visually obstructing the cultural relic, while the Lying Rainbow is an arch bridge that complements the existing bridge's shape. Both bridge forms accentuate the visual significance of the existing bridge. The new bridges harmonize with the historic fabric while establishing a dialogue between the past and present. The Lying Rainbow features a stone exterior embellished with intricate folding lines. Beneath the surface, diamond-shaped aluminum panels constitute an arching posture, evoking a sense of fluidity and grace.

Conversely, the sleek stainless-steel façade of Tranquil Wave gracefully exudes an air of weightlessness, thereby minimizing its visible presence on the surrounding landscape. Further accentuating their contemporary elegance, both bridges showcase railings crafted from ultra-white glass juxtaposed against customized stainless-steel columns. The bridgeheads and waterfront platforms, constructed with cast-in-place hydrophilic concrete and prefabricated concrete fiber panels, evoke a sophisticated organic aesthetic.

Confronted with constrained scales, Building Information Modeling (BIM) is an essential tool for navigating intricate structural challenges. Rigorous simulations guarantee structural integrity and an optimal user experience. A systematic development and experimentation approach minimizes joints in the facade, further enhancing the design's aesthetic.
