Illawarra Convoy shuts roads Sunday with speed cuts to 40km/h
Trucks and motorbikes travel between Appin and Shellharbour from 4:30am to 5pm, forcing lane restrictions and speed limits.
If you're driving in the Illawarra Sunday, plan for significant delays. The convoy will close or restrict lanes on Appin Road, the M1 Princes Motorway, the Princes Highway, and several side roads.
Speed limits drop to 40km/h from 4:30am to 5pm. The Princes Highway will close between Helensburgh and Maddens Plains in the early morning while trucks gather.
The right-hand turn from Mount Ousley Road onto the M1 northbound closes between 7am and noon. Drivers heading north are advised to use University Way instead.
Transport NSW reminds motorists that heavy vehicles need more stopping room and have large blind spots.
