South African National Roads Agency Limited (Sanral) CEO Nazir Alli has told Eyewitness News he believes South Africa is not a lawless society and expects a surprising number of motorists to pay for e-tolls.
"We are a law-abiding society in South Africa," he said, adding, "I think once people actually start to see and enjoy the benefits of the thing [e-tolling], people will pay."
Alli also believes his organisation has been as transparent as possible in implementing e-tolling, which now looks set to launch within weeks.
"I don’t know how much more transparent we can be when we’ve actually taken all of our tender documents and we’ve had it on our website."
On Wednesday, President Jacob Zuma signed a bill into law which frees up Sanral to launch the multi-billion project.
The news has been met with scepticism and anger.
A protest against the signing of the bill is being planned for Friday.
But Alli denies e-tolling is being launched with questions hanging over the project.
He says Sanral is ready to launch e-tolling and is waiting for the final go ahead from the transport minister.
"Technically, we’ve been ready for two years now. The system is already working."
It's now expected e-tolling will commence next month.
Critics say they'll be watching to see if Sanral's systems are able to cope.
Also on Wednesday, the Supreme Court of Appeal heard a challenge against e-tolling and has reserved judgment in the matter.
