A construction worker was killed and two others hurt when they became entangled in wiring that got stuck under a pick-up truck on Long Island, authorities said.

The hardhats had positioned cable guide wiring on the roadway of North Bicycle Path in Port Jefferson Station shortly before 1:30 p.m. Friday, with the intention of hoisting it into position above the street, Suffolk County police said.

But before the construction crew was able to do so, a 2016 Chevy pick-up truck drove over the wire, which then got caught in the vehicle’s undercarriage.

As the cable was pulled, it became taut and caused the truck to overturn — entangling and dragging all three workers in the process, police said.

One of the hardhats, identified as 22-year-old Maspeth resident Arthur Oldakowski, was rushed to John T. Mather Memorial Hospital, but he could not be saved.

The two others were taken to Stony Brook University Hospital, where Rodrigo Corrales, a 50-year-old worker, was listed in critical but stable condition, and Anes Music, 23, was being treated for minor injuries, cops said.

The truck driver, whom police identified as 41-year-old Bryan Masem, was not injured.

Cops asked anyone with information about the incident to call 631-854-8652.
