Question

Same design as described in #3.9. Use two methods to find the elevation of PVT. (Note: Method 1 uses the straight gradeline; Method 2 uses the vertical curve)

3.9 An equal-tangent crest curve connects a +2% initial
grade with a -1% final grade, and is designed for 55
mi/h. The station of the PVI is 233 + 40 with elevation
1203 ft. What is the elevation of the curve at station 234
+00?
