The Arizona Department of Transportation (ADOT) used an innovative approach to planning of improvements for State Route 179, called a Needs Based Implementation Plan (NBIP). Preserving the scenic beauty of the drive and the values of the community that live around this route are central to ADOT's approach on this project. The 17-month NBIP planning process was completed in December, 2004.

All activities and information from the NBIP process have been archived on this site. You can use this NBIP Archive site to review all reports, activities, communications, etc. that took place during the 17-month NBIP process. It is saved here as a historical record of the NBIP process.
