  "description": "This crop shows plan views of two bridge bent caps (Bent 4 Left and Bent 4 Right) along SR 21, each supporting six beam bearing lines with detailed dimensioning of bearing spacing, dowel hole locations for smooth dowels, skew angle, and stationing. The drawing includes references to bridge sheet 16 details (Detail 3 and Detail 4) and station/PGL callouts for SR 21 westbound and eastbound alignments, documenting the substructure bent cap geometry and beam seat layout at Bent 4."
