Design Criteria for the Preparation of Improvement Plans

 

The Department of Transportation has extensively updated our design criteria manual and construction standard drawings.

We focused these revisions to achieve the following:

  1. Update Americans with Disabilities (ADA) guidance
  2. Improve transparency for our customers
  3. Clarify our criteria
  4. Allow for greater design flexibility
The Design Criteria and Standard Drawings became effective on May 1, 2020. Projects submitted prior to the effective date may use the expired criteria or adopt the new policies.
