Geometric layout plan for a trumpet interchange on a major expressway. Mainline stationing covers KM 101+190 to KM 102+240, including full horizontal alignment data for Ramps A, B, C1 and D. Curve parameters range from R=60.00m to R=2000.00m with spiral transitions (TS, SC, CS, ST) and PRC points defined. Drainage design includes several relocation canals with widths (B) of 1.0m, 2.0m, and 3.0m, plus pipe culvert details (dia. 1.5m). Toll plaza and administrative office area are shown with basic building footprints. Side slopes are indicated with typical 1:1.5 to 1:2 batters depending on embankment height. Project includes stationing for designed boundaries and existing topographic features.
