Five more highways have agreed to participate in the open toll payment system to begin in mid-September.
Works Minister Alexander Nanta Linggi said they are the Damansara-Puchong Expressway (LDP), SPRINT Highway, Shah Alam Expressway (Kesas), SMART Tunnel and Kuala Lumpur-Putrajaya Expressway (MEX).
"As I have said before, the open payment system will be implemented in phases involving various concession companies.
"Negotiations on this are an ongoing effort by the ministry and need to be done to ensure the successful implementation of the multi-lane fast flow (MLFF) system," he said in a Facebook post today.
Nanta previously announced that six highways, along with the Butterworth-Kulim Expressway, would implement the open payment system to allow users to pay toll using other means.
He said this would bring the total number of highways involved to 11.
Nanta also announced that the Sungai Besi Expressway would be the first location for the implementation of MLFF proof of concept (POC).
"This will be done at the end of October to evaluate the MLFF system before it is implemented at all highways in Malaysia.
"The ministry is also in negotiations with other concession companies to get another highway for the implementation of the MLFF POC. I will announce the location of the second POC in the near future," he said.
