  "description": "This crop shows the right-hand portion of two half plans of a skewed bridge — one at deck level (with barrier line, bearing/pedestal squares at 3500 spacing and 30° skew) and one at foundation level (two skewed pile-cap/raft blocks with pile circles at 3750 spacing, separated by a PCC M15 median wall and terminated by independent retaining walls) — drawn to 1:300. Grid bubbles P1 and A1 fix the 40000 (SQ) / 46189 (SK) span, with the centre line of the expansion joint at A1 and traffic direction to Khandwa. At upper right is the 1:2000 key plan showing the proposed structure hatched across the river/drain at chainage 64+412, structure type MJBR, 2X40m span, 30° skew, new construction, with ROW lines, retaining/toe walls and chainage marks 64+400 and 64+500."

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."

The span between P1 and abutment A1 is dimensioned 40000 square / 46189 skew, with the centre line of the expansion joint at A1 and traffic direction to Khandwa. A KEY PLAN (1:2000) at top right locates the proposed structure at CH 64+412, a 2x40 m MJBR with 30° skew, new construction, crossing the Sipra River / earthen drain between chainages 64+400 and 64+500, with ROW lines and retaining/toe walls indicated."

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."

Behind the abutment the drawing documents 600 thk filter media, an independent retaining wall with its own footing (dashed), embankment fill at 1:2 slope with stone pitching, and a tapered approach slab element at the left. The girder is cut by a break line on the left, so only the abutment end of the superstructure is within this crop; no reinforcement detailing or elevations/stations are shown."

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."

  "description": "This crop is the longitudinal elevation (scale 1:300) of a two-span bridge between abutments A1 (Dewas side) and A2 (Khandwa side) with a single intermediate RCC column pier P1, spans of 40000(SQ)/46188(SK) and 46000(SK)/46188(SK), precast PSC girders with deck continuity over the pier, POT-PTFE bearings (FR free / FX fixed) and expansion joints at both abutments. 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": "This crop is Section A-A through abutment A2 of a bridge, drawn at 1:150, showing the end of a reinforced concrete box girder deck bearing on the abutment via a pot-PTFE bearing with an RCC seismic stopper and an expansion joint at deck level. Behind the abutment it documents the approach embankment with 1:2 batter, stone pitching, 600 thick filter media, an independent retaining wall with its own footing, and the approach slab at left. Below ground the abutment is founded on a pile cap 12300 long with four 1200 dia bored cast-in-situ piles at 3600 centres and 750 end offsets, drawn in hidden line."
