Design Exceptions

What is the design exception process used for?

Design Exception FormThe design exception process is intended to ensure that sound engineering decisions are made when design options are limited.

Exceptions to design standards should be discussed early in the design process when project limits are first determined. All design exception requests must show justification.

Who determines when an exception is acceptable?

The Oregon Department of Transportation state highway engineer is responsible to set design standards and evaluate whether modifications are appropriate.

Design engineers cannot design outside the standard without approval.

Applying for a Design Exception

Please note:
  • Applying for an exception does not guarantee approval.
  • Exceptions must be submitted at or before the Design Acceptance Package milestone.

Request Forms

Instructions to complete the form:

Design Exception Review Process

Once received, the request is reviewed by three representatives, prior to the state roadway engineer completing an evaluation. Those representatives include:

  1. Engineer of record;
  2. ODOT program manager, area manager, district manager, private public partnerships, or local government representative; and
  3. ODOT region technical center manager or region roadway manager.

If approved, the region manager will submit the request to the state roadway engineer who will provide the official approval.

Additional information about this process is included in chapter 14 of the Highway Design Manual.
