Which sheets lack sheet identification boxes in their upper right corners?

The sheets that lack sheet identification boxes in their upper right corners are indeed the roadway and traffic design standards. This is due to the specific formatting and presentation requirements associated with these types of sheets. Roadway and traffic design standards typically contain design guidelines, specifications, and standard details rather than project-specific information, which is why they do not require a sheet identification box.

In contrast, signalization and traffic plans, structures and signalization plans, and roadway and highway plans are more project-oriented and often require identification boxes to help in tracking, referencing, and coordinating the various elements of the project. These identification boxes provide critical information such as sheet numbers, titles, and revisions, which are essential for anyone reviewing or using the plans.

By understanding the distinct purposes and content of these different types of sheets, you can appreciate why roadway and traffic design standards do not incorporate sheet identification boxes, thereby simplifying their design and reaffirming their role in providing consistent guidelines rather than unique project details.
