These informational resources display the sequential numbering system present along roadways within the state. These numbers, usually accompanied by state route designations, indicate the distance from a boundary line or starting point of that route. For instance, a sign reading “I-80, Mile 125” signifies a location 125 miles from Interstate 80’s origin point within the state.
Understanding this location system is crucial for navigation, emergency response, and infrastructure maintenance. Accurate positional data facilitates efficient routing for travelers, allows emergency services to quickly locate incidents, and aids transportation departments in managing road assets and planning repairs. The implementation of this system dates back to the early days of highway development, evolving to meet the increasing demands of a modern transportation network.
