Transport minister Wee Ka Siong said the proposal to implement either a congestion charge or environmental fee will be decided once MRT3 is fully operational and the city has a “completed public transport network system”.

Wee said the project received the Cabinet’s approval on March 4 and its first phase is scheduled to be open to the public in December 2028.

“Once it is completed in 2030, we will relook the fee structure for vehicles entering the city,” he said when replying to a question from Fahmi Fadzil (PH-Lembah Pantai) on whether the government is planning to impose such a fee.

“This is the correct trend (to introduce the fee) for not only vehicles entering the city but in terms of environmental protection, too.”

He said similar fees are already in place in other major cities around the world, although electric vehicles may be given exemptions.

On concerns by Sri Hartamas residents about the project’s proposed route, Wee told Hannah Yeoh (PH-Segambut) that a two-month engagement period will kick off in July, and that it is not too late to implement “engineering solutions”.
