The construction workers had stopped traffic to move a tractor trailer, but a man driving his car couldn't wait.
"He got out of his car, starting screaming, ranting and raving," witness Michael Guinan said.
Witnesses say he got back into the car and started rolling at the workers.
Worker Pete Jablonski's head hit the windshield.
Luckily, he was wearing a helmet at the time.
Two other workers were dragged a short distance by the car.
The driver has been identified as Don Myers.
He once worked for Mayor Street in the Mayor's Office of Community Services.
Myers currently works for a city contractor as director of the RHD Ridge Center, an intake center for homeless men.
Police records show he has been arrested 11 times.
That includes another road rage incident two years ago, in which he allegedly pulled a gun on a delivery driver blocking his way.
The workers who encountered him today say he seemed crazed.
The three injured workers were treated and released from the hospital.
Police arrested Myers when he returned to the scene, with an incredible demand.
"He pulled up here and said something to the fact, you guys have to pay for my windshield," Guinan said.
Myers is now facing three felony charges of aggravated assault. It appears he was too impatient to wait in traffic for a couple of minutes. Now he faces 10 to 20 years in jail if convicted.
