This 51.7 km (32.1 mi) dual-carriageway provides links to the booming towns in southern Klang Valley, including the country's administrative capital, Putrajaya.

The first 7.95 km (section 1A) stretch that starts at the UNITEN interchange in Bangi is toll free, and had been open for several years.

The section 2 stretch of the expressway from Bandar Saujana Putra towards Teluk Panglima Garang measuring 12.96 km long would have been completed in 2011.

A runaway truck ramp, to stop vehicles unable to brake, is provided on both ends of the Selat Lumut-SKVE Bridge.

In 2015 section 1A of the expressway (toll-free) was in a state of poor maintenance, with most of its street lights not functioning and wrecked guardrails unreplaced at accident sites.
