A vertical road was designed with three tangent lines having a grade of 7.0%, -4.9%, and 2.2%, consecutively. The intersections of the three lines are known to be V1 and V2 having an elevation of 223.34m and 209.89m respectively. The said tangent lines will be connected by a summit and a sag unsymmetrical parabolic curve which meets at point A having an elevation of 212.91m above sea level. The L1 of the summit curve is 113.61m and the maximum offset of the sag curve is 0.28 multiplied to the maximum offset of the summit curve. Point A is located at the line that connects the two vertices. What is the elevation at the end of the road in meter?
