Roadway Design Plans
Roadway Design
The Roadway Design Section’s responsibility typically begins with the scoping phase of the project. Roadway provides Predesign with comments and design solutions during the development of the Project Assessment. Roadway Design projects range from minor pavement preservation projects to highly complex grade and drains. During the Design phase for grade and drain projects, the Roadway Design Section is responsible for the geometric aspects of the construction project based on a previously determined scope.
Roadway Predesign

The Predesign Section prepares and reviews Scoping Documents, Change of Access Reports and Design Exception/Variance Requests.

Pavement Design Plans
Pavement Design

The Pavement Design Section provides the following information and design guides that are available to design new flexible and rigid pavements and for rehabilitation treatments for existing pavements nearing the end of their service life.  We also provided services to review and approve pavement designs prepared by consultants for ADOT projects.  Below is guidance for preparing pavement designs used on ADOT projects statewide.


Survey tripod on site
Engineering Survey

Engineering Survey supports the delivery of Base Mapping or Topographic Maps for Final Design, Concept Design Reports, Project Assessments, or Feasibility Studies. The section manager sets the standards, provides direction, and helps to make decisions for project priorities by working with the Project Managers and Design Discipline Leads based on their project needs, values, and urgencies.

Men reviewing plans

Roadway Review supports the delivery of the Five-Year Program by reviewing scoping documents, permits, plans, specifications and estimates to ensure they are constructible, cost effective and in compliance with the appropriate policies, standards and procedures.

Americans with Disabilities Act (ADA) Sign

The ADA Section oversees the implementation of ADOT’s Americans with Disabilities Act (ADA) Transition Plan related to roadways within public right-of-way.  The section provides guidance related to ADA requirements and standards throughout the development process.
