The Arizona State Transportation Board has scheduled a special meeting Friday to award a grant to one of three bidders to work on a system that could help stop wrong-way drivers.
The board's decision will follow its approval last month of a $3.7 million plan to construct a thermal-detection system after Gov. Doug Ducey called for state agencies to combat the issue.
The Arizona Department of Transportation says the project will span a 15-mile stretch of I-17.
The Wrong-Way Driving Detection Pilot Project will use thermal-detection cameras to sense wrong-way vehicles and alert those drivers and others on the freeway with warning signs and advisories. The system will also notify authorities and highway patrol.
