The symbol on the map for an expressway is represented by what?

The symbol for an expressway is represented by a shield. This is a widely recognized symbol in roadway signage, particularly in the United States, where it signifies a major highway or interstate. The shield shape helps differentiate these important routes from other types of roads, highlighting their purpose for faster, unrestricted travel and a focus on handling higher traffic volumes.

Using a shield as a symbol conveys the idea of safety, protection, and structure associated with expressways. This is crucial for drivers to easily identify these roads while navigating, ensuring they can make informed decisions, such as merging, exiting, and maintaining appropriate speeds. Understanding this symbol helps drivers anticipate the nature of the roadway ahead and prepare accordingly for highway driving conditions.
