We are working on the Warringah Freeway from 10pm Friday 26 December 2025 to 6pm Sunday 25 January 2026.
With fewer vehicles using the Warringah Freeway during the holiday period, we can take advantage of the lower than normal traffic volumes and close lanes for longer. The temporary traffic changes allow us to create safe work areas next to, over and on the freeway. This gives us consecutive day and night access to the freeway so we can carry out critical work activities like removing and installing asphalt and concrete across the freeway lanes, which cannot take place during normal traffic periods. This increases our project’s efficiency, reducing the overall impact to the community compared to delivering this work during single night shifts or extended weekend shifts.
During this period, we will be working at different areas along the Warringah Freeway between Milsons Point and Naremburn at key interchanges. At this stage we are planning to work at the locations and dates shown in Table 1 below.
