Pedestrian Walkway Tunnel

A 4 m bay of covered pedestrian walkway threaded under the scaffold along an existing pavement: a 2.2 m clear width and 2.4 m headroom between ply-clad scaffold-tube uprights, a boarded and sheeted roof with a fall to the road, a handrail to the kerb side.

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
