a). The highway location as shown in Figure 1 is located in rather steep area with high rainfall. The road are designed for two-way two-lane traffic, with right and left shoulder, exclusive lane for motorcycle and the speed limit is 50 km/h. Based on all information above, you are asked to identify the road profile and select the appropriate road furniture, traffic signs and pavement markings for the highway. Explain your design.

b) This area would contribute to high water discharge and high velocity of water due to the steep slope. Therefore, we have to investigate the water sources and the mode of potential failures. Sketch the cross section of each point (marked with “X”) with incorporations of possible sources of water in that area. Discuss each of the sources and drainage system design that could be considered
