An incоming grаde оf -1.60% meets аn exiting grаde оf +3.5% at a PVI having station 17+66.74 and elevation 119.33’. An unequal tangent vertical curve is designed to meet these tangents, with horizontal lengths of the curve before and after the PVI of 700.00’ and 300.00’, respectively. What is the grade of the inserted tangent?
