plain in the south-east to the Woronora Plateau in the north-west, rising over in doing so. The pass has a scenic lookout at the top of Bulli Mountain, near Sublime Point Lookout, and this is the sight of the under construction Southern Gateway project. The pass is protected bushland under the Bulli Pass reserve and walking tracks to the lookouts are under repair since 2003. The pass was the first major route out of the plain, not including Mount Keira Road built in 1834 by convicts or O'Briens Road, a private tollway. The Bulli Pass is mainly a two lane undivided road with a steep, winding alignment through a geologically constrained area. The pass has steep slopes both above and below the road. The maximum grade on Bulli Pass is 14.6 per cent. In 2014, the average daily traffic volume over the pass was 12,000 vehicles with an annual growth rate of 1.4 per cent. Heavy vehicles account for about five per cent of total vehicle movements over the pass. In 2008 the pass was subject to a major rock fall that required slope stabilisation works with the Princes Highway closed for seven weeks. Following a serious rock fall in 2015 that landed on a vehicle, there were extensive investigations into the upslope section of Bulli Pass. To ensure the long term safety and stability of Bulli Pass,
