Given the following data for a vertical curve of a road; G1=-2.5%, G2=+5.5% and station of PVI=250+50.At station 252+50, the vertical curve must intersect an existing road at elevation 48.48ft. the elevation on the tangent section at station 256+50 is 67.55. What is the length of the vertical curve? and what is the elevation of the road at station 244+50?
