  "description": "This crop shows two plan views of Bent 1 bent cap for a bridge over SR 21 (right and left segments, split by the roadway alignment), detailing beam centerline spacing for Beams 1 through 12, bearing centerline locations, dowel hole details for a 1 1/2\" smooth dowel, and skew angle of approximately 81°-20'-05.0\". Stationing for the beginning of the bridge and the B.F.P.R. reference point at Bent 1 is called out, along with cross-references to Detail 1 and Detail 2 on Bridge Sheet 16. This is a fragment of the bent cap plan documenting bearing/dowel layout and beam spacing, not a complete bridge plan."
