  "description": "This crop shows a combined Plan and Elevation of a twin (left and right parallel) roadway bridge structure crossing an existing and future railroad track alignment plus a future access road, at the intersection with SR 21. The plan view details bent locations (Bents 1-4, each split into L/R for the two parallel bridges), skew angles, wall/wingwall faces, minimum vertical and horizontal clearances to the tracks, and various stationing/bearing callouts; the elevation view below shows the four bents with bearing types (EXP/FIX), span lengths (55'-82'-55' totaling 192'-0\"), chain link fencing, and existing/future groundline references. A partially visible notes/table block at bottom right lists general notes and a location table for left/right bridge clearances, but this text is cut off in the crop."

  "description": "This crop presents a combined Plan and partial Elevation of a twin bridge structure (Left Bridge and Right Bridge) crossing a railroad and future access road at a skewed angle, with Bents 1 through 4 identified. The plan shows deck geometry, clearance envelopes (point of minimum vertical clearance, existing and future), stationing along SR 21 and the railroad centerline, and horizontal/vertical clearance callouts; the elevation below shows bent locations, bearing types (EXP/FIX), pile schematics at Bents 2 and 3, fencing, and groundline references. A partial schedule table and general notes referenced elsewhere on the sheet govern clearance minimums and station/elevation measurement conventions but are not reproduced here."

The sheet appears to document both superstructure endwall/deck geometry and appurtenant fence/security barrier details for a bridge, likely along SR 21."

Notes at the top define the variable haunch dimension 'D' at interior and exterior beams and specify constant slab thicknesses. This documents deck slab and diaphragm reinforcing and geometry for the bridge superstructure, part of the beam/slab framing plan sheet."

  "description": "This crop is a cross section labeled 'SECTION THRU EDGE BEAM' showing a transverse cut through a bridge superstructure with a series of precast I-shaped beams supporting a sloped deck slab, tagged individually as I-508, I-509, I-802, I-801, and 2-800. Dimensions call out 2-inch edge clearances and an '8-404' equal beam spacing, along with a 2% cross slope referenced to the SR 21 WB profile grade line (PGL). Notes address edge beam pour requirements, formwork removal timing tied to concrete strength, omission of bearing pads and fence from the drawing, and a tapered parapet/fence support element at the deck edge."
