Gutters sit at -10 m south and +10..12 m north, a ~2% crown between them, and the envelope runs 0.6-1.0 m per section. Gutter spacing independently confirms the 20.9 m carriageway measured from the crossing. The sharpest breaks are 0.09-0.12 m/m, so 3DEP does not resolve a kerb upstand: kerb height stays a recorded assumption rather than a derived value.
