Which sheet displays the shape of the road's side slopes and ditches?

The correct response pertains to the section sheet, which specifically illustrates the vertical cross-sections of the roadway including the side slopes and ditches. This sheet reveals how the road is constructed in relation to the surrounding terrain, showing details such as the slope angles and the relationship of the ditch to the road itself. These details are critical for understanding drainage design and the overall grading of the roadway.

In contrast, the plan sheet typically provides a top-down view of the project layout, which does not include vertical profiles or side slopes, while the profile sheet focuses on the road's elevation and grade changes along the centerline but does not show lateral features such as ditches. The cross-section sheet does include side slopes but is more a specific rendering at intervals along the road, rather than a continuously detailed representation of all slopes and ditch configurations. Thus, the section sheet is the most accurate choice for comprehensively displaying road side slopes and ditch shapes.
