• Location: Coconino County, Arizona

B&N completed a study that identified operational, safety, and access management improvements for an area with heavy freight traffic within the I-40 corridor across northern Arizona. B&N inventoried and assessed existing conditions, recommended improvements, developed an implementation schedule, and prepared Planning and Environmental Linkage (PEL) documentation. The final plan included a roundabout and access management techniques that will defer the need for major traffic interchange improvements for 20 years. This study also provided guidance for Coconino County access management guideline considerations, with specific measures for the Bellemont area. B&N facilitated a public-private cost sharing agreement for implementation. The improvements were later designed by B&N and constructed in 2021.
