  "description": "This crop shows two cross sections of a precast girder bridge superstructure: an upper 'SECTION THRU SLAB' spanning six beams (Beam 1 through Beam 6) with full deck slab dimensions, cross-slope, reinforcement (400A, 500A, 501, 502 bars), overhang and edge details, and a lower 'SECTION THRU DIAPHRAGM' showing diaphragm reinforcement (403A, 402A, 507A bars) and a plain tie bar between the same beam line. Notes at the top explain the variable dimension 'D' used to set beam elevations relative to the slab for dead load deflection and vertical curve compensation. This documents deck slab and diaphragm concrete/reinforcement quantities for a multi-beam concrete bridge deck."

Together these views document the deck slab geometry, beam layout, cross slope, and diaphragm reinforcement for this bridge structure."
