Roadway Design Standards and Guidelines
Roadway Design begins with the scoping phase of the project and continues through the delivery of construction plans for a project. Roadway Design projects range from minor pavement preservation projects to highligh complex highway facilities. The design of these improvements are based design standards, criteria and guidelines approved by the Department.
Roadway Design Standards
The design standards team develops, maintains and provides technical support for the Roadway Design Guidelines, Policies, Standards and Procedures; Construction Standard Drawings (C-Stds); Design Detail Drawings; and all CADD-related configurations, standards, guidelines and training.

County Maps
The information in the links below was created to allow visitors to view existing county maps of the state of Arizona. The group that produced these maps was dissolved in 1995, and they are no longer being updated by ADOT personnel. Be aware that some of the routes have been redesignated to different route numbers and are not shown on these maps.

To see the maps in some browsers, please allow pop-ups on this page, and make sure that "Display PDF in Browser" is checked in Adobe Reader/Acrobat Preferences.
