A -3% grade meets a +5% grade near the 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 necessa co use a curve that lies 200-meter on one side of the vertex of the straight grade and 100-meter on the other side The stationing of the beginning of the curve (200m side) is at 10+000 and its elevation is 228m. Determine the elevation at station 10+040. If the uphill edge of the underside of the bridge at station 10+220 is at elevation 229.206m, what is the vertical clearance under the bridge at this point? Determine the stationing of the lowest point of the curve.
