3. A 300 ft vertical curve connects a-2.3% approach grade and a +1.6% departure grade. The PVI is at 45+65 with elevation 369.22'. The curve is designed for 35 mi/hr speed limit. Calculate stations and elevations for PVC and PVT A 4% grade meets a failing grade of-25%. Station at P1 is at 60+00 and elevation is 95 feet. The length between PVC and PVT is 1400 feet. Find the elevation of the curve at station 58+00 4.

A grade of -2.353% intersects a grade of -1.212% at station 77+70 whose elevation is 412.85 feet, the distance back to the BVC is 600 feet, and the distance to the EVC is 450 feet. Compute the elevations of the full stations on this unequal length vertical curve. I am having a very hard time visualizing this but a diagram might help if possible!

EXIT 211 A A 2,125 ft equal tangent vertical curve joins a +2.2% grade to-3.6% grade. The PVI of the vertical curve is station 55+21 at elevation 150 ft. To meet MUTCD standards for advance guidance, an overhead sign structure must be placed at station 55+85. The bottom of the sign will be 18 ft above the roadway surface (more than the recommended 16.5 feet to accommodate larger trucks that use the roadway). WEST 56 Utopia Botlom of sign 18...
