On a certain highway a -6% grade meets a +2% grade at station 70 + 00, elevation 550.97 ft. An equal tangent vertical curve, 800 ft. long, is to be installed to connect these two grades.
a) Calculate the elevations of stations at 100ft intervals along that curve. Tabulate the result and do the usual check.
B) Find the station and elevation of the low point of the curve.
