Abstract:The Arizona Department of Transportation (ADOT) Traffic Safety Section recognized that a significant portion of Arizona’s fatal crashes were of the run-off-roadway crash type along rural two-lane highways, as is typical for most states with significant mileage of rural highways. The ADOT Traffic Safety Section took a systemic approach and reviewed twolane rural highways with a higher potential for run-off-roadway crashes. One of the priority corridors for shoulder widening as a federal Highway Safety Improvement Program (HSIP) funded project was State Route 264 (SR 264) from Burnside Junction to Summit in Northern Arizona. This is a 24.55 mile corridor from Milepost (MP) 441.19 in Burnside Junction to MP 465.74 at the Summit. This section of SR 264 is located in Navajo County, Arizona, within the ADOT Holbrook District and is shown in Figure 1. SR 264 through this section is classified as a rural minor arterial and runs east-west. The area of interest is currently a two-lane rural highway, with intermittent right- and left-turn lanes and passing lanes.
