North–South Expressway

The North–South Expressway Northern Route is an interstate controlled-access highway running parallel to the northwestern coast of Peninsular Malaysia. The 460-kilometre expressway forms the north section of the North–South Expressway, passing through the northwestern states of Kedah, Penang, Perak and Selangor. The expressway begins at the Bukit Kayu Hitam checkpoint in Kedah where the Malaysia–Thailand border lies, and ends at Bukit Lanjan in Selangor where the expressway interchanges with the New Klang Valley Expressway. The expressway is operated by PLUS Expressways.

The expressway runs in a north–south direction close to the northwestern coast of the peninsula, connecting several major towns including Alor Setar, Butterworth, Taiping, Ipoh and Rawang while also providing access to several rural villages on its path. The expressway runs parallel to the existing Federal Route 1; it is also concurrent to the expressway from Bukit Kayu Hitam to Jitra.
