The basic component materials of Dagu Bridge consist of orthogonal heterosexual steel bridge surface, steel box arches, prestressed steel strands, concrete piers, bearings, bridges, drilling perfusion pile foundations and parallel steel wire harness booms. The design of the bridge is conceived as "Sun Moon Arch" or "Sun Moon Double Whisper Arch"[[3], consisting of two asymmetrical arches, the arched ring facing the east, symbolizing the sun, 39 meters high, arc length of 140 meters, tilting outward to 18 degrees, small arch facing west, symbolizing the moon, 19 meters high, arc length of 116 meters, tilting to the outside of 22 degrees. The large arch and small arches are a total of 88 booms on both sides of the Dagu Bridge, carrying all the weights of the 106-meter main span of the bridge, echoing the semi-circular viewing platform stretching out of the bridge, and is a "asymmetrical floating joint beam arch bridge".[4]
