  "notes": "Counterpart to curb-sidewalk-segment and tileable with it: seam edges exactly at x = -1.0 / +1.0 m with full 150 mm kerb reveal, same gutter plates, kerb profile, 285.7 mm slab grid (7 x 7), joints and materials; every seam lies in a joint. Kerb dropped to 30 mm above the gutter for |x| <= 0.857/2 m (aligned with the slab grid), footway falls towards the kerb over five slab rows, back two rows stay level. White tactile paving over the three middle slab columns: two rows of ribbed guidance slabs (ribs pointing across the road) at the kerb, blister slabs as locating strip up to the building line. Hidden bottom and contact faces removed.",
