Roadway Cross Section An existing ground cross section of 150’ on a highway project was surveyed as shown in Figure 1 with the center line at X=75. The surface is

accurately estimated with the equation shown in figure.The following cross section design criteria are to be used: Table 1. Cross section design criteria Compute the key X positions and Y elevations at the edges of lanes, shoulders, slopes, and ditches.Determine where the daylight connections (X and Y values) are made on each side of the cross section. Include all calculations with a labeled/dimensioned sketch and submit as a memo with your narrative.
