It’s a super day (to designate a driver)

No matter what team you’re rooting for in the Super Bowl (or maybe you’re just waiting for the halftime show), we want to remind drivers to have a plan to get home safely after the game is over. 

If you’re out on Arizona highways on Sunday, you may notice a traffic safety message encouraging motorists to designate a driver on overhead message signs.

The Arizona Department of Transportation, in partnership with the Hopi Tribe, has completed the State Route 264 Corridor Planning Study. 

The purpose of the corridor study was to identify improvements that need to be made along 96 miles of SR 264 from Moenkopi to the Navajo-Apache County line (mileposts 322-418). The study makes short- and long-term recommendations to improve the highway by:

  • Assessing existing conditions

  • Completing and reviewing historical crash data

  • Performing road safety audits

  • Gathering input from tribal leaders and community members

View the Final Report

While the study identifies needs along the highway corridor, funding still needs to be identified and secured in order to implement these recommended improvements.

ADOT thanks all community members for their participation and involvement in the study.
