This expressway provided fast and convenient connectivity between Kuala Lumpur, the capital of Malaysia and Putrajaya – the new Malaysian Government Administrative Centre, Cyberjaya – the core of the Multimedia Super Corridor (MSC) and KLIA.

[1] Extending 26 km in its first phase, MEX is designated as the Protocol Expressway that links Putrajaya, Cyberjaya, KLIA and LCCT with Kuala Lumpur.

[2] Maju Expressway was planned to extend to KLIA by Dec 2019 and the route will be 18 km-long, three-lane dual carriageway and commence at Putrajaya Main Interchange.

The development stage of the Kuala Lumpur-Putrajaya Expressway created a controversy due to the effects of the construction to the houses of the residents in Sri Petaling.

[5] Despite the complaints and protests by the residents, the Malaysian Minister of Works, Datuk Seri S. Samy Vellu insisted that sound barriers would be installed along the Sri Petaling section and the Sri Petaling flyover would be made higher to reduce noise pollution.

Originally, motorcyclists were used to be allowed on the expressway and both Putrajaya and Salak toll plazas included motorcycle lanes.
