The core structure of the covered wooden arch bridge involves "weaving beams into an arch." Builders interlace short timbers both longitudinally and transversely—overlapping, pressing, and lapping them together—to form a stable arch-frame system. At the bottom, three timber segments form the "three-side arch", constituting the primary load-bearing system. Above this, five timber segments form the "five-side arch", which serves as the secondary load-bearing system. Each timber joint is tightly interlocked using mortise-and-tenon joinery, such as dovetail joints and through-tenons. The bridge's rafters fit tightly against one another, and its beams interlock seamlessly, resulting in very close-fitting connections.

Intangible cultural heritage inheritors CHEN Changsheng and LU Sunfu will use timber components and traditional tools on-site to construct a two-meter, true-to-scale model of the Baixiang Bridge, offering a live demonstration of this unique craft.
