a -3.7% garde meets a 7.3% grade at vertex (El.139.88m) directly under an overpass bridge having underside elevation of 157.37m . A 7.8m clearance under the bridge and the center of the curve was observed. Determine the elevation at the bottom of the invert when its location from PC is 86.7m. The pipe has an outside diameter of 1.3 meters and a thickness of 61.2mm. The backfill is 0.6 m in depth. The bridge is having a width of 16.3m
