A construction worker was killed Saturday while erecting the inaugural Formula 1 Las Vegas Grand Prix.

The man suffered a “major laceration to the neck” while working at the site’s Bellagio Fountains on the Las Vegas Strip around 11:30 a.m., according to the Las Vegas Metro Police Department.

The injured worker was rushed to an area hospital, where he later died.

The Occupational Safety and Health Administration is investigating the workplace tragedy.

No other details were immediately available.

The worker was likely helping build MGM Resorts International’s grandstand for VIP race viewing in Bellagio Lake, where the famous fountains are located.

The 3.8-mile Vegas Grand Prix circuit is set to wind its way through downtown Sin City in November.

It is estimated that as many as 300,000 F1 fans will attend.

MGM Resorts International did not immediately respond to The Post’s request for comment.
