Authorities say an Arizona Department of Transportation employee has been killed while setting up a sign alerting drivers to pavement repairs along Interstate 10 south of Phoenix.
ADOT officials say 55-year-old Frank Dorizio died Wednesday afternoon.
They say he’s the first ADOT worker since 1998 to be fatally struck while working along a highway.
The Arizona Department of Public Safety is investigating the death and there’s no immediate word on a possible suspect.
Dorizio was a member of ADOT’s Incident Response Unit, which sets up traffic control, removing debris and assisting stranded motorists.
He joined ADOT in October 2015 as a highway operations worker.
