Overpass Deck Span

Precast concrete overpass deck span 8m wide and 16m long on the 2m grid, a row of 1.2m deep girders under a flat road slab with solid concrete parapets along both edges.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
