Inquiries are continuing into a crash which has seriously impacted traffic on the M1 Motorway at Berowra this morning.
Emergency services were called to scene shortly after 3am today (Wednesday 23 October 2019), after a roadworker was struck in the breakdown lane by a utility, driven between the roadwork safety vehicle and the rock wall.
The 28-year-old roadworker was treated at the scene by paramedics for head injuries before being taken to Royal North Shore Hospital in a serious condition.
The driver of the utility, a 72-year-old man from Kingsgrove, has also been taken to Royal North Shore for mandatory testing and to be treated for a minor head injury.
Officers from Ku-Ring-Gai Police Area Command attended and established a crime scene; however, inquiries are now been taken over by the Crash Investigation Unit (CIU), who are on site.
Advice from the Transport Management Centre are that motorists are advised to avoid the Pacific Motorway with all northbound lanes of the M1 closed and motorists are being diverted onto the Pacific Highway at Windybanks Interchange.
Southbound motorists can now use the M1 to travel south but are doing so on the northbound carriageway. Southbound motorists can also divert onto the Pacific Highway at the Berowra off-ramp.
Traffic is very heavy in both directions, especially southbound.
Motorists should allow plenty of extra time, expect delays, reduce speed and exercise caution.
Anyone needing to travel between the Central Coast and Sydney, including HSC students, should consider catching a Central Coast and Newcastle Line train instead.
