Butterworth Outer Ring Road

The Kilometre Zero of the expressway is located at Sungai Dua Interchange. Ships can be seen near Bagan Ajam Rest Area. The Penang Megamall is located at the end of the highway. It is a six-lane line and it is also the connecting highway to Federal Route 1, from which north bound traffic will bring travelers to Alor Setar and beyond while motorists travelling south can head to Ipoh and beyond.

Construction began in 2003 and work was completed in 2006. The expressway was open to motorists in January 2007. As Sg Nyior residents protested against high toll rate in February 2007, the Sg Nyior toll booth collection was postponed by the Ministry of Works.

This highway is built to reduce the heavy traffic on the Sungai Dua–Juru NSE in the rushing hours and the holiday seasons. Nowadays, it is also used by residents in the Raja Uda area to head to Perai and the Megamall Pinang.

The people of Raja Uda area can also travel on the highway to head to the Sunway Carnival Mall.

With just one toll payment, this highway will bring motorists from both the south and the north to the ferry terminal for onward faster and cheaper ferry-crossing to Penang since the Penang Bridge faces heavy traffic congestion.

Notable features of the expressway include Sungai Prai Bridge over the Perai River and Sungai Maklom Bridge over the Maklom River.

The Butterworth Outer Ring Road uses open toll systems.
