Motorists have been urged to pay attention to the road, not the view, when driving on Sea Cliff Bridge following the death of a motorcyclist.
Initial police investigations have suggested the 38-year-old Gwynneville man crossed on to the wrong side of Lawrence Hargrave Drive and collided with a car.
The crash happened about 12.45pm on Saturday and closed the bridge for several hours while crash investigators established a crime scene. Police arrived to find the man had become trapped beneath a car and had died.
NSW Fire and Rescue Service Bulli station Commander Bob Hunter attended the scene and said motorists needed to be diligent when using the bridge.
"Don't get too wrapped up in the view," Commander Hunter said.
"It is a very windy bridge and you need to be aware of what's happening around you."
Last month, the bridge was closed after a 44-year-old man fell from his bike and sustained injuries.
Commander Hunter said while the bridge wasn't a notorious crash spot, it was a unique structure requiring a specific type of response.
"We have to treat the bridge as a tunnel," Commander Hunter said. "Getting to an incident ... it's like getting to a brick wall; there's nowhere you can go so you have to turn back."
Commander Hunter said the bridge became particularly busy on weekends, with much of the traffic travelling from the north.
"It is on our radar as a certain area we have an interest in because there are certain things we have to do differently," he said.
Police urged anyone with information to call Crime Stoppers on 1800 333 000.
