SINGAPORE : There are currently no plans to set up Electronic Road Pricing gantries in the underground portion of the Central Expressway, said Senior Parliamentary Secretary for Transport Teo Ser Luck in Parliament on Wednesday.
This is because it does not pose as much of a safety risk as the nine-kilometre-long Kallang-Paya Lebar Expressway (KPE).
But if the safety situation changes or travel speeds fall below the threshold level of 45 kilometres per hour, gantries will be installed and activated.
Mr Teo was responding to questions from MPs on whether gantries would be built on other expressways in anticipation of slower traffic flows.
He explained that as three-quarters of the nine-kilometre KPE is underground, the impact of an incident there would "multiply many fold" if traffic is congested.
So authorities are making the upfront investment of some S$24 million to build the 16 gantries first, even though not all of them will be activated when the KPE opens in September.
Mr Teo said: "The rationale is unique to the KPE in view of the safety concerns and is not applied to arterial roads or other expressways on the surface.
"The 16 gantries... (are) on the entries and exits... So based on the distance and where there are exits, we place the installation of the gantries accordingly..." - CNA/ms
