A crane at the No. 7 train subway-extension construction site collapsed Tuesday night, killing one worker and injuring three. An 80 and 40-foot section of the 170-foot crane broke off and plummeted to the ground at around 7:20 pm at the West 34th Street and 11th Avenue site, according to the NY Post.

It sounded like a bomb went off, said one worker. When I turned, I didn't see the crane, the one that's always there. So we knew what it was right away. We saw a plume of smoke.

The 30-year old worker who was crushed by the falling crane has been identified as Michael Simermeyer of New Jersey. Three other works were hurt by debris, one of whom suffered from a broken leg and was later taken to Bellevue Hospital.

Authorities believe that the crash may have been caused by a snapped cable, but an official statement has not been released. Work was suspended at the site and the surrounding blocks were closed off as authorities cleaned up the area. 

The crane was owned and operated by Yonkers Contracting Company, according to the Metropolitan Transportation Authority. The MTA later released a statement saying, We pray for the recovery of the workers injured. We will work with all proper authorities to conduct a thorough investigation.
