24 people have died in construction zones this year. Five of those were construction workers and a sixth was a tollway worker walking between toll booths, according to the Illinois Department of Transportation. Nationally last year there were 1,181 fatalities in construction zones. More than 80 percent of such fatalities involve people riding in the cars. The state has tried, boosting the fine for work zone speeding, but construction season remains hazardous in Illinois. The state is posting more signs to raise awareness.
