If a roadway has multiple highway numbers, what is reported?

In situations where a roadway is designated by multiple highway numbers, the convention is to report the lowest number highway. This approach aligns with the standardized practices of highway identification as it simplifies navigation and communication about the roadway.

The lowest highway number is often considered the primary designation for the roadway, serving as a clear reference point for drivers and transportation agencies. This method also reduces confusion, as it provides consistency when multiple designations exist for the same segment of roadway.

In contrast, options like reporting the highest number, the priority level, or the most traveled highway do not adhere to established reporting standards and could introduce ambiguity in roadway identification.
