WidthWwants m/mmnot establishedThe single crop is a chainage/level data table; it contains no plan or cross-section giving a carriageway width. Attributing the clipped "3700" figure to the carriageway would be an invention.not found
Total LengthL_totalwants m/mm46.188 mLHS: 64+406.385 - 64+360.197 = 46.188 m. RHS: 64+417.675 - 64+371.487 = 46.188 m. Both sides give the same chainage interval, so length along the main carriageway between the two tabulated (start/end) locations = 46.188 m.The table lists chainages for the main carriageway at two locations (per the crop description, presumably the two ends/abutment lines of the structure) for both LHS and RHS. The difference of the chainages is the length between those two stations, and LHS and RHS agree exactly, which supports the interpretation. However, the crop does not state outright that these two chainages are the extremities of the main carriageway extent being quantified, so the value is marked low confidence.derivedcheckp2 · p02_r06

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.

  "description": "This crop is a chainage and level data table that accompanies an ELEVATION view drawn at scale 1:300 (the elevation itself lies above/outside this crop, only a clipped dimension line and figure remain at the top right). The table gives chainages, finished road levels (FRL) and existing ground levels for the left-hand and right-hand sides of the main carriageway at two locations, presumably the two ends/abutment lines of the structure. It documents the survey and setting-out data for the structure's start and end, useful for earthwork and substructure height take-off but containing no quantities itself."
