The pass has been on the Roads and Maritime Services’ radar for a number of years as traffic flow increases.

Various studies have looked at a range of options to deal with traffic in the area.

These have included the idea of drilling a tunnel to replace the road (which was dismissed as being too expensive), widening the road up the pass or leaving it as is and creating a new third crossing of the escarpment.

Also under consideration has been a long-term option of extending Memorial Drive to the hairpin on Bulli Pass.

Roads and Maritime Services has been working on a corridor strategy for Bulli Pass between George Avenue, Bulli, and Bulli Tops to define how travel needs will be managed over the next 20 years.

“Corridor strategies are being prepared for major state roads in NSW to outline a 20-year plan to manage traffic and safety,” an RMS spokesman said.

“The strategies aim to identify sections of road requiring attention, which can then be prioritised for action in future funding programs.

“The Princes Highway corridor strategy was released about a month ago.

“The Bulli Pass corridor strategy is expected to be released in coming months.”

RMS is also looking at the traffic congestion along the Princes Highway at Bulli.

This section of the highway has become an increasing source of frustration for local residents as more and more traffic lights are installed. 

“The Princes Highway traffic study is under way to identify ways to improve traffic flow on the Princes Highway in Bulli,” the RMS spokesman said.

The physical study of the highway at Bulli is due to be completed by the end of the year but the results would not be released until some time in 2017.

“Results from the study will be input into the Thirroul to Unanderra corridor strategy which is expected to be released in the next 12 months,” the RMS spokesman said.
