A horizontal alignment consists of two tangent lin connected by a horizontal curve, as shown in figures below. PC is located at sta. 10+00.00. The overall length of the horizontal curve is 400 feet and an 8% superelevation needs to be designed for the curve. The superelevation runoff length is chosen to be 240 feet. The normal cross-section is also shown in the figure. Both left and right sections have 2% slopes for drainage. On the circular curve, the left section is on the external side and therefore needs to be raised while the right section is on the internal side and should be lowered. The rotation axis is on the center line of the highway, which is shown as a black dot in the figure.
