NHI Evaluating & Designing Improvements to the Interstate System Class
Taught by the National Highway Institute and Sponsored by ITD and FHWA

This is a FREE National Highway Institute Class (NHI) being offered by the Idaho Transportation Department to our partners.  Class size is limited to 2 staff people per agency please (there is only a total of 20 spots available for consultants at this class), so register early!

This intense 2-day course provides participants with key knowledge of freeway systems and interchange types, FHWA policy on justification for interchange access approval, and applications of technical knowledge and policy understanding to interchange project decisions. Topics covered in this course include service and system interchange types, interchange justification process, interchange study and selection process, fundamentals of freeway system operations and planning, urban freeway diagnosis, geometric design considerations, and technical and documentation procedures.

Upon completion of the course, participants will be able to:

  • Compare and contrast design and operational attributes of different freeway types
  • Interpret and apply principles of good freeway systems and interchange design
  • Describe the application of design exceptions to interchange project decisions
  • Describe the content of an appropriate safety and operational analysis to support an access request
  • Compare alternative designs based upon an assessment of appropriate measures of effectiveness (MOEs)
  • Apply an interchange design study procedure

At the conclusion of the course, each attendee will receive an NHI certificate of training and 16 hours can be used towards PE credits.
