Normally, the top half of a plan and profile sheet displays a _______ view.

The top half of a plan and profile sheet typically displays a plan view. This view represents an overhead perspective of the area being examined, showcasing horizontal arrangements of features such as road alignments, utilities, and other relevant elements on the ground. The plan view serves as a crucial tool for understanding spatial relationships and the overall layout of the project, allowing planners and engineers to visualize how various components interact within the plan's footprint.

Plan views are integral to civil engineering and public works projects because they provide a clear and concise representation of the design intent before any vertical or spatial changes are depicted, which would be found in the profile or elevation views. The lower half of the plan and profile sheet would typically show the profile view, which indicates the vertical alignment and grade changes along the proposed route. This combination of views aids in comprehensive project planning and helps in communicating design information effectively.
