A road's bridges: wherever a road runs more than BRIDGE_FILL over the land (roads.ts), a deck carries it, built here as a mesh in the game's frame. The deck is a slab under the road's points, a metre wider than the road, its top 3 cm under them (never in one plane with the ground graded to the road where the deck begins), so the road lies on what collides. It has a railing along each edge and piers down to the land every 16 m. Flat colours, faces turned out.
