Revised: June 9, 2023

It is our utmost pleasure to assist software users in the development of roadway projects using Computer-Aided Drafting and Design (CADD) in the most accurate and efficient manner available thereby making the best possible use of time and resources.

Our goal is to support designers in accomplishing roadway projects in a timely manner so regardless of what other CADD support effort we may be working on at the time, our software users and their projects always come first!

Either face to face or via email, phone or Teams, it is our duty to assist TDOT personnel and consultants with problems they may be encountering.

Tennessee is on the road to Digital Delivery with OpenRoads.

TDOT ORD Roadmap


TDOT is currently using ORD 2022 Release 1 (10.11) for any new projects, but recommending that projects that were begun in ORD 2021 Release 1 or 2 (10.10) be developed in 10.10 since there are issues with the uplift process. 

As of July 2021, all new projects should be surveyed in ORD. Existing projects will be analyzed on a project-by-project basis to determine if a project should be converted to ORD. Therefore, consultants should coordinate with their applicable TDOT design manager to determine if a project should be converted or not.
