The Roadway Data page provides a bounty of data such as locational information, jurisdiction, functional classification, surface type, and reference points; control section records and construction project logs. Information from the trunk highway roadway history file can be generated by request.
The roadway data is subject to ongoing revisions which result in differences in the information presented on reports over time. Several reports are based on the most current data; therefore, the information is subject to change. To allow for consistency, the VMT and Mileage reports on this web page are based on a "snapshot" of the data which is taken during every mid-year. Therefore, the statistics remain constant until another snapshot is taken. The data and statistics presented may vary from the information obtained from other sources.

(Centerline) Miles and Lane Mileage - Centerline Miles is a term for one mile of a single roadway, regardless of the number of lanes. (If a road is divided, mileage is not doubled.) Lane Mileage refers to a multiple of continual driving lanes and centerline mileage. Both types of figures can be organized by city, county, route system, surface type, and functional class.
