Worker injured after crane collapse at new Sydney Fish Market site

The company constructing the new $750 million Sydney Fish Market building has confirmed one worker was injured when a crane collapsed at the the site today.

The crane jib fell onto scaffolding at the Blackwattle Bay site on Bridge Road in Pyrmont just after midday.

Paramedics treated one man, aged in his 30s, for minor back injuries.

Multiplex confirmed the crane collapsed within the grounds of the site.

"The site has been evacuated and there is no risk to the workforce or public," Multiplex said in a statement.

"We are offering our full support to emergency services, SafeWork NSW and the workforce.

"We will work with the relevant authorities to carry out a full investigation."

A witness, Steven, told Nine radio station 2GB the crane "sliced right through to the second level with the scaffolding" at the site.

Fire and Rescue NSW and police crews responded to the collapse.

"A man was treated on scene by NSW Ambulance paramedics and will be taken to St Vincent's Hospital in a stable condition," NSW Police said in a statement.

"Safe Work NSW will investigate the circumstances surrounding the incident."

Live Sydney Traffic said one eastbound lane of Bridge Road was closed at Wentworth Park.

"Traffic is slow both ways and there are a lot of pedestrians in the area," Live Traffic Sydney said.

The new Fish Market will cost NSW taxpayers $750 million.

Replacing the existing market nearby, the precinct is expected to attract six million people each year.

"The design is a world-class piece of architecture, with a distinctive wave-shaped and scale-patterned roof that pays homage to the fishing industry," the project is billed on its website.

The new building is due to open in 2024.
