“The total traffic volume across the three port crossings has already exceeded the peak level recorded before the time-varying fees were implemented,” the newspaper said.
It also said that although overall peak hour conditions remained better than before the scheme was introduced, congestion at certain times continued to impact connecting roads and non-port traffic.
“Therefore there may be a need to make adjustments to the time-varying fee structure in the future to respond to changing times,” she added.

The administration also warned that the behavioral impact of the initial toll levels will gradually diminish amid economic growth and inflation, reducing their effectiveness in managing traffic.
