Concern about a ventilation Ventilation outlet will be located near the tunnel ramps, in the Balgowlah outlet being located in the Golf Course precinct, which is the most efficient location Burnt Bridge Creek valley Air quality assessment, taking into account local conditions including topography, is being undertaken and will be included in the EIS

Desire to keep the shared user The shared user path crossing Burnt Bridge Creek Deviation will be path under Burnt Bridge Creek maintained throughout and after construction Deviation

Beaches Link – Project update 29 Beaches Link vertical alignment Cammeray to Balgowlah

Most of the project will be deep underground in tunnels. This greatly reduces surface impacts, including to private property, communities and the environment.

The tunnels, built mostly through high-quality Sydney sandstone, will be engineered and constructed by industry leaders using world-class technology, and will be world’s best practice in terms of safety, efficiency and road user experience. The vertical alignment diagrams show the approximate depth of the tunnels below the surface along the alignment of the Beaches Link tunnel. The depths, shown in metres, are measured from ground level to the road surface in the tunnel.
