Both vertical and horizontal curves on the same section of a highway are designed at the same speed. A vertical sag-curve on this highway connects G1=-7% and G2=? % grades and is 300 m long.

You are asked to design a horizontal curve for a four-lane road. The road has 12-ft lanes. Due to expensive excavation, it is determined that a maximum of 42 ft can be cleared from the road’s centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximum superelevation of 0.08 ft/ft. What is the highest possible design speed for this curve?
