The mission of the Geometrics section is to provide technical assistance on geometric design features (superelevation, horizontal and vertical alignment, intersection design, interchange design). We accomplish our mission by assisting the district personnel, other governmental agencies and consultants in applying the geometric criteria.

Geometric Review

This section performs geometric reviews of construction plans for conformance with the ODOT design standards of the Location and Design Manual, Volume 1, and provides geometric review training for the Districts.

GRAD Training

Geometric Review and Design (GRAD) Training

GRAD is a self-paced engineering resource providing a comprehensive overview of the design components within the Location & Design Manual Vol. 1.  Whether you are new to design or a seasoned user of the Location & Design Manual Vol. 1, these modules will provide viewers with an understanding of the key elements of roadway design.

Design Exceptions

A design exception is the formal documentation of the justification to deviate from the established design criteria. The controlling criteria which requires a design exception are lane width, shoulder width, bridge width, structural capacity, horizontal alignment, vertical alignment, grade, stopping sight distance, cross slope, superelevation, vertical clearance and horizontal clearance. Design exceptions should be submitted prior to the Stage 1 submission. The format for the design exception can be found in the L&D manual Volume 1 section 105.5.1.
