  "description": "This crop is a paired half plan of a skewed (30°) two-carriageway highway bridge: the left half shows the deck level and the right half (partly cut off at the sheet edge) shows the corresponding foundation level, both at 1:300. 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."

It documents the superstructure (precast PSC girders, deck with continuity over the pier, RCC crash barriers, pot-PTFE bearings marked FR/FX, expansion joints) and the substructure/foundation (wall type abutments, pile caps on 1200 mm dia cast-in-situ piles, approach slabs on PCC leveling course, independent retaining walls with filter media, stone pitching and launching apron). A tabulated schedule below gives chainages, finished road levels and ground levels at LHS/RHS for each of A1, P1 and A2; the notes block at lower right is partially cut off at the crop edge."

It states dimensional conventions, live load design cases (IRC Class A / 70R / SV), concrete grades for each structural component, clear cover values, reinforcement grade, expansion joint and drainage spout specifications, wearing course thickness, seismic/wind zone and exposure, backfill properties behind the RE wall, and piercap/bearing pedestal level assumptions. No structural geometry is drawn here; quantities must be read from other sheets, using this crop only for material grades, covers and the stated 300 T vertical / 50 T lateral tentative pile working loads."

It also shows the substructure and foundations — wall type abutments and pier on pile caps (12300 wide at abutments, 5100 at pier) supported on 1200 dia RCC cast-in-situ piles at 3600 spacing — together with approach works: 300 thk approach slabs on 150 thk PCC levelling course, independent retaining walls, stone pitching over 600 thk filter media, launching aprons and 2:1 embankment slopes. Below the elevation is a levels table giving chainages, FRL and existing ground levels at LHS/RHS for A1, P1 and A2, and at the right edge a partially cut-off general NOTES block covering units, loading class and concrete grades."

  "description": "Crop shows two cross sections of a precast prestressed concrete girder drawn side by side at 1:50 — the support (end-block) section on the left where the web is widened to the full 800 bottom width, and the mid-span I-section on the right with a 300 thick web. Both sections are 2650 deep overall with a 1000 wide top flange, 150 thick at the tip, and an 800 wide bottom flange (250 deep at mid section). Dimensions are unitless as printed (implied millimetres); no reinforcement, prestressing strands or material notes are shown in this crop."

  "description": "This crop is a full-page block of general notes for a bridge drawing, enclosed in the sheet border, with no graphical construction detail. It states dimensioning conventions, live load design cases, concrete grades for each structural component, reinforcement cover and steel grade, wearing course thickness, expansion joint and drainage requirements, backfill and seismic/exposure data, and cross-references to alignment, plan-profile and miscellaneous drawings. It closes with a small table of tentative working pile loads (max. vertical 300 T, lateral 50 T), useful for specification and material take-off assumptions rather than direct quantity measurement."

The RCC crash barrier is called out by leader but its profile is not drawn within this crop, and a partial dimension '25' at the right edge is cut off."
