LengthLwants m/mm80000 (SQ) / 92378 (SK) mmMedian runs continuously between the two carriageways over the full bridge length. Bridge length from the two dimensioned spans: 40000(SQ) + 40000(SQ) = 80000(SQ); along skew 46189(SK) + 46189(SK) = 92378(SK).No dimension is given for the median itself longitudinally. The only length available is the span dimensioning A1–P1–A1 (two spans of 40000 SQ / 46189 SK), which is the bridge length the median accompanies. The median also continues over the approaches (approach slabs and footpaths are shown beyond A1), so this figure is the on-structure length only — hence low confidence.derivedcheckp1 · p01_r02p1 · p01_r02 half plan showing deck level foundation level
WidthWwants m/mm2900 mmDimension stated in the cross-width dimension stack of the half plan at deck level: 'Median width = 2900', appliesTo 'median between carriageways'. Confirmed identically in both crops.The value is stated outright as the median width between the two carriageways, in two independent readings of the same plan.readp1 · p01_r02p1 · p01_r02 half plan showing deck level foundation level
HeightHwants m/mmnot establishedA plan cannot establish a height, and no cited dimension is owned by the median vertically. Requires a typical cross-section of the median (marked 'MEDIAN PCC') which is not in these crops.not found

Worked out by anthropic/claude-opus-5 from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.

It documents the general arrangement — approach slabs and footpaths at abutment A1, one 40000(SQ)/46189(SK) span to pier P1, five girder lines at 3500 c/c per carriageway, RCC crash barriers with deck drainage spouts at 5000 typical, a 2900 median within an 80000 ROW, and pile groups/foundation outlines at A1 and P1. Only half of the structure is drawn; the second span beyond P1 and the retaining wall callout on the right are incomplete in this crop."

  "description": "This crop is a general arrangement plan of a two-span skew bridge (30° skew) for a dual carriageway, drawn as a half plan at deck level on the left and a half plan at foundation level on the right (the latter is cut off at the right edge). It shows two separate decks — right side and left side of the median — each 16550 wide with 13500 carriageway, five longitudinal girders at 3500 centres, transverse members at 5000 typical, bearings at abutment A1 and pier P1, RCC crash barriers, approach slabs, footpaths and fan-shaped embankment turfing beyond the abutments. Spans are dimensioned both square and along the skew (40000 SQ / 46189 SK), with the foundation plan showing circular foundation elements at 3750 spacing and an independent retaining wall callout partly outside the crop."
