Queues of cars stretched across the Lincoln Causeway this morning as the new Border restrictions and permits came into play.
Service NSW went live at 4pm yesterday to allow border residents to access permits for essential cross-border closure.
More than 400 cars have been turned around since the border restrictions began.
The Transport Worker's Union earlier said the Service NSW site crashed at about 11pm last night after truck drivers were forced to apply for new permits.
