A grade of -2.353% intersects a grade of -1.212% at station 77+70 whose elevation is 412.85 feet, the distance back to the BVC is 600 feet, and the distance to the EVC is 450 feet. Compute the elevations of the full stations on this unequal length vertical curve. I am having a very hard time visualizing this but a diagram might help if possible!
