What do section sheets commonly show regarding the proposed road?

Section sheets are an essential part of road design plans that provide a cross-section view of the proposed roadway. These sheets depict a vertical slice of the road at specific points, illustrating the typical shape and dimensions, including the width of lanes, side slopes, shoulder specifications, and any other features such as drainage components. This cross-sectional detail is crucial for understanding how the road will interact with the surrounding terrain and for guiding construction.

While elevation views show how the road will look from the side and traffic patterns provide insights into how traffic will flow, these aspects are not the primary focus of section sheets. Additionally, material specifications detail the types of materials to be used in construction but are not represented in the section sheets themselves. Thus, the primary purpose of section sheets to show the typical shape and dimensions of the proposed road is what makes this answer the correct choice.
