The estimated cost of the Rapid Transit System Link (RTS Link) infrastructure project had increased by 29.9 percent or RM1.20 billion to RM5.24 billion as of Dec 31, 2023, compared to the original estimated cost of RM4.03 billion in January 2018.

According to the Auditor General’s Report 2/24, this increase was partly due to the expansion of the depot work scope from light to heavy maintenance, new contracts for the Traffic Diversion Scheme, and the construction of the Customs, Immigration, and Quarantine (CIQ) Complex.
