- Two sections of a highway are separated by 800m. The initial grade is +3.0% and the final grade is -1.0% and the elevation is 12m. Determine the curve lengths required for a 120km/hr vertical alignment to connect two highway segments, keeping the connecting grade as small as possible.arrow_forwardplease be sure answer is correct.arrow_forwardConsider the same vertical curve from Problem 1 that has a +3.2% initial grade and -1.1% final grade. The point of vertical intersection is at station 98+20. The highest point of the curve is at station 100+79.35 to meet drainage design. What is the station of the point of vertical curvature (Also known as beginning of vertical curve). 92+88.95 92+90.81 92+88.05 (INCORRECT) 92+91.23 This is Question 1: Consider a vertical curve with a +3/2% initial grade and -1.1% final grade. The point of vertical intersection is at station 98+20. The highest point of the curve is at station 100+79.35 to meet drainage design. What is the design speed, in mph? Correct answer here is 70 MPHarrow_forward
