The state Legislature will hold a public hearing Friday, Feb. 28 on whether the new road treatment chemicals being used by the state Department of Transportation damage vehicles faster than the old mix.

State Sen. Kevin Kelly, who represents Shelton, said the hearing will allow members of the public to tell state officials about any concerns they have due to the change.

“Trucking industry officials note that the new chemical the state uses, magnesium chloride, can rust out undercarriages faster than other chemicals the state has used,” Kelly said. “They are urging the state to add rust inhibitors to the saltwater mix that is currently being put on the roadways.

“Mechanics say they are replacing brake lines sooner on vehicles,” he continued, “and many of you have told me the chemicals pose a danger not only to cars and trucks but to state bridges that are rusting prematurely.”

Legislation has been introduced

Kelly said legislation has been introduced — Bill 5288, An Act Concerning Chemical Road Treatments — that would require the state transportation commissioner to study the corrosive effects of chemical road treatments.

To submit testimony at the hearing, people should email Transportation Committee clerk Nick Neeley at, and “cc” Kelly at (put “Bill 5288” in the Subject line).

Kelly represents the 21st Senatorial District, which includes all of Shelton and parts of Monroe, Seymour and Stratford. He is a Republican in his second term.
