A section of a two-lane highway (12-ft lanes) is designed for 75 mph. At one point, a vertical curve connects a -2.5% and +1.5% grade. The VPT of this curve is at station 25+00. It is known that a horizontal curve starts (has PC) 292 ft before the vertical curve VPC. If the superelevation of the horizontal curve is 0.08 and the central angle is 38 degrees, what is the station of the PT?

Question

A section of a two-lane highway (12-ft lanes) is designed for 75 mph. At one point, a vertical
curve connects a -2.5% and +1.5% grade. The VPT of this curve is at station 25+00. It is known
that a horizontal curve starts (has PC) 292 ft before the vertical curve VPC. If the superelevation
of the horizontal curve is 0.08 and the central angle is 38 degrees, what is the station of the PT?
