stone bridge 3d model

Create a highly accurate 3D model of the stone bridge shown in the reference image. Reproduce the bridge architecture and proportions as closely as possible. A long, elegant historic European stone bridge with three large semicircular masonry arches, spanning a shallow canal or river. The bridge has a slightly curved/rising roadway, with the center of the bridge gently higher than both ends. The entire bridge structure is constructed from aged beige/tan natural stone blocks, with clearly visible individual rectangular masonry blocks and realistic stone joints. The side walls are solid stone parapets with a slightly curved upper edge following the bridge deck. On both sides of the bridge is a distinctive dark wrought-iron railing, consisting of repeated vertical decorative metal posts connected by horizontal rails. The posts have ornamental details and small decorative spherical/rounded elements. Reproduce the railing pattern along the entire length of both sides.
