How do you check road construction levels?

For road profile, slope is constant from X1 to X6 at 2% Difference in length is dx = 25m, so we can find the difference in height using the given slope. This is added to the road level at X1 to find the road level at X6 => road level at X6 is 24.500+0.500 = +25.000m.
