The main bridge of the Hutuo River Bridge, a single-tower, single-pylon cable-stayed bridge, is inspired by "landscape painting", featuring a unique "scroll-shaped" tower with a spatially twisted cable arrangement. The bridge has a span arrangement of (40 + 150 + 150 + 40) meters and utilizes a fully floating system. The structural support system incorporates vertical seismic isolation bearings, longitudinal and transverse dampers, and transverse wind-resistant bearings. The tower’s cross-section transitions from oval at the base to circular at the top, with decorative scroll edges rotating counterclockwise at approximately 90° from the base to the top. The tower above the deck is steel, while the part below the deck is concrete, with a steel–concrete transition section near the deck level. The main girder uses a double-box steel structure with transverse beams. The stay cables are made of 1860 MPa-grade steel strands, with an anchorage spacing of 9.0 m along the cable-stayed beam. Unlike the traditional fan-shaped cable arrangement, this bridge adopts a reverse layout, with the outermost cable having the lowest anchorage point on the tower. The foundations for the bridge towers, auxiliary piers, and edge piers are all constructed using bored piles.
