Kuala Lumpur Middle Ring Road 2 (MRR2 or Kuala Lumpur Middle Ring Road 2 Scheme), Federal Route 28, is a ring road built by the Malaysian Public Works Department (JKR) to connect neighborhoods near the boundary of Federal Territory of Kuala Lumpur and Selangor. Altogether, the 65.0 km (40.4 mi) of the entire system consists of Federal Route 28, Damansara-Puchong Expressway E11 (from Sri Damansara Interchange to Sunway Interchange) and Shah Alam Expressway E5 (from Sunway Interchange to Sri Petaling Interchange). However, the Kuala Lumpur Middle Ring Road 2 is generally referred to as Route 28 since Route 28 occupies about two-thirds of the system.
