A -3% grade meets a +5% grade near an underpass. In order to maintain the minimum clearance allowed under the bridge and at the same time introduce a vertical transition curve in the grade line, it is necessary to use a curve that lies 200-m on one side of the vertex of the straight grade and 100-m on the other. The station of the beginning of the curve (200-m side) is 10+000 and its elevation is 228 m. Determine the stationing of the lowest point of the curve. Determine the elevation at station 10+040. If the uphill edge of the underside of the bridge is at station 10+220 and at elevation 229.206 m, what is the vertical clearance under the bridge at this point?
