Emergency services are working to free a ‘severely trapped’ driver after their truck collided with multiple vehicles on a bridge north of Sydney. 

Emergency services were called to the Hawkesbury River Bridge near Mooney Mooney, 58km north of Sydney, just before 7.20am on Thursday following reports of a multi-vehicle crash. 

It’s understood a truck and a car collided in the southbound lanes, trapping one of the drivers.

Fire and Rescue NSW Superintendent Adam Dewberry said crews were working to free the driver of the truck who was ‘severely trapped’. 

‘We have a very serious crash, someone severely trapped in one of the vehicles, ambulance paramedics are on the scene stabilising,’ Mr Dewberry said on 2GB.

‘Firefighters are working with the paramedics to start to work out how to rescue this person out of the vehicle.

‘That includes cutting and pushing of the vehicle to gain access to it so they can treat the injuries and then get them out and into hospital as soon as possible.’

The condition of the driver is not yet known.

Emergency responders have also called a Toll rescue helicopter to the scene.

Authorities have closed all southbound lanes of the M1 and one of three northbound lanes as emergency crews work to free the driver.  

Authorities have warned drivers to avoid the area and expect significant delays. 

The collision has caused massive delays for the peak-hour morning commute, with traffic at a standstill for kilometres and queuing past Calga. 

Northbound traffic has also been impacted, with congestion already stretching for three kilometres. 

Motorists are being urged to use diversions and to exit via the Mount White Interchange for the Pacific Highway.

Live Traffic NSW advises the diversion is suitable for ‘light vehicles only’, with heavy vehicles being parked.
