The IDOT CADD Standards/Downloads subscription service for Consultants, Local Agencies, and other Departments of Transportation will allow information about updates or additions to be sent out in a more timely manner.

IDOT maintains separate web pages for both CADD Standards & Downloads, and Bridges and Structures CADD Support. When updates or changes are made to the CADD files they can be downloaded from these pages. The subscription service will provide a means to notify end users of these changes in order for them to download the latest versions and keep their IDOT CADD files up-to-date.

The service is an open list; therefore, end users need to register in order to receive electronic notification of changes and updates. A valid e-mail address and Internet access are required to register for the service. In order to subscribe, you must fill out all required fields marked with a red asterisk.

You will NOT be notified of changes made to Highway Standards or the CADD Roadway Drafting Reference Guide by subscribing to this service.

If you have questions or problems concerning the service please contact: IDOT CADD Support
