"These are mothers, fathers, brother and sisters just doing a job. They go to work each day expecting to be able to go home safely at the end of the day. Safety is our highest priority, but we can't keep our people safe if other people selfishly show no regard for their well-being."
Hori-Hoult said a few road cones and a sign offered no protection from a speeding vehicle and urged motorists to slow down and keep to the temporary speed limit.
Abuse was another hazard the road workers were subjected to.
In one recent case a man got out of his vehicle and was shouting and waving his arms around like he wanted to start a fight with the female operator who was on her own at the time.
Such incidents are reported to police.
"No one ever gets to their destination faster by abusing or shouting at a stop/go operator," Hori-Hoult said.
The job of the operator was to keep traffic moving in both directions when the state highway was reduced to one lane.
"We try to keep delays to a minimum but sometimes traffic builds up. We try to get people on their way as quickly as possible."
Road workers began work last week after time off during the busy holiday season.
"The summer months are our busiest time of year for road resurfacing and repairs as we try to take advantage of the dry conditions and long sunny days. This work is essential for the safety and resilience of the state highway network, so we ask motorists to be patient and understanding."
