A crest and sag curve connect a 0% west highway segment (left) with a +1.50% east highway segment (right). The 0% west highway segment is at a higher elevation than the start of the +1.50% east highway segment. The two vertical curves connect with each other (PVT = PVC) and share a 1.9% (use -1.9% for calculation) common grade. If the design speed of the curves is 65 mi/h. What is the elevation difference (ft, use format 0.00, range is +/-0.03) between the two road segments?
