PHOENIX - The triple digits are unbearable to walk in, but imagine working in it.

Crews with the Arizona Department of Transportation building the 202 South Mountain Freeway brave the hot temps to work on the concrete.

All of the construction and maintenance crews have received training on the dangers of extreme heat.

More than 1,500 workers are assigned to the project and, in the past year, there has been no reported heat-related illnesses.

ADOT provides shaded areas and cold bottles of water with electrolyte powder.

There are also neck guards and cooling towers for workers.

Each worker undergoes a class on working in the heat and is assigned a “buddy” to monitor.

Medical technicians are also on standby, if needed.
