More Early Work On M1 Upgrades between Kariong, Somersby interchanges Artists impression of Kariong to Somersby upgrade

Motorists are advised of changed traffic conditions on the M1 Pacific Motorway in preparation for a major upgrade between Kariong and Somersby interchanges.


Early work will be carried out from tonight until Wednesday 28 March between 8pm and 5am, weather permitting.This stage of work will include investigations ahead of major work starting after the Easter long weekend.


The first stage of major work will start from Tuesday 3 April and will be carried out between 8pm and 5am on weekdays. It is expected this stage of work will be completed in six weeks, weather permitting.


The work includes line marking to define changed travel lanes, progressively rolling out the reduced 80km/h roadwork speed limit between Kariong and Somersby and placing barriers on the motorway to set up a safe work zone. This will allow building a third lane on the motorway, while maintaining two lanes in each direction to minimise traffic disruptions.


For the safety of workers and all motorists, the night work will require lane closures and a 40km/h speed limit.


All lanes will reopen to traffic and speed limits will be returned to 110km/h from 5am to 8pm until the start of barrier placement work from Tuesday 3 April. A reduced 80km/h speed limit will then progressively be installed and will remain in place for the duration of the project.


Motorists are advised to drive to the conditions and follow the direction of signs and traffic control.


There will be no work carried out during the Easter long weekend, with all lanes operating as usual at 110km/h from Thursday 29 March to Monday 2 April inclusive.


Roads and Maritime thanks motorists for their patience during this time. For the latest traffic updates download the Live Traffic NSW App, visit or call 132 701.


The project is expected to be completed in 2020, weather permitting.
