  "description": "This crop contains two bridge deck cross sections: a 'SECTION THRU SLAB' showing six precast beams supporting a cast-in-place concrete deck slab with cross slope, overhangs, edge curbs, and detailed reinforcement (400A, 500A, 501, 502) with clear cover callouts and beam spacing dimensions; and a 'SECTION THRU DIAPHRAGM' below it showing intermediate diaphragms between the same six beams with reinforcement (403A, 402A, 507A) and a 1\" diameter plain bar. Together these document the deck slab thickness, camber/build-up dimension \"D\" for interior/exterior beams, overall deck geometry, and diaphragm reinforcement layout for this bridge span."

It documents deck cross-section geometry, endwall/joint details, security fence construction requirements per Georgia DOT specifications, and end bent reinforcement layout for the barrier and beam seat area."

  "description": "This crop contains multiple bridge structural details: a full-width cross section thru an endwall showing girders, deck slab, endwall heights, and joint fillers with rebar marks (4-900A/B); a set of fence notes governing chain link security fence construction; a fence elevation and fence post detail showing pipe post dimensions and bracing; and a section at the endwall (End Bent 1/4) showing reinforcement bars, bearing area (not shown), and waterproofing callout. The sheet appears to document both superstructure endwall/deck geometry and appurtenant fence/security barrier details for a bridge, likely along SR 21."

  "description": "This crop shows two related cross-sectional details of a precast concrete girder bridge superstructure: an overall 'Section Thru Slab' spanning six beam lines (Beam 1 through Beam 6) with full deck geometry, cross slope, overhang details, and reinforcement bar callouts (500A, 501, 502, 400B/C series); and below it a 'Section Thru Diaphragm' view showing the intermediate diaphragms cast between the bulb-tee beams with reinforcement bars (403B, 402B, 507B) and a 1\" diameter plain bar. 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."
