Design Criteria and Standard Drawings Announcement

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

We focused these revisions to achieve the following:

  2. Improve transparency for our customers
  3. Clarify our criteria
  4. Allow for greater design flexibility
The revised Design Criteria and Standard Drawings will take effect on May 1, 2020. Projects submitted prior to the effective date may use the currrent criteria or adopt the new policies.
