  "description": "This crop shows a partial plan view of a bridge deck edge, including an RCC crash barrier running along the top edge, a series of small bearing or support symbols spaced at a typical 5000 unit interval, and a pier/support point labelled P1 with associated skew and square dimensions. Hatched rectangular blocks along the skewed lower-right edge likely represent bearing pads or joint details at a pier or abutment line. The crop appears to document part of the deck plan layout with dimensioning for skewed versus square measurements relative to a support point."
