History The North–South Expressway northern route, being part of the larger North–South Expressway network, was constructed in phases simultaneously with the south section. The first segment on this expressway, from Bukit Kayu Hitam to Jitra, was opened on 1 April 1985, originally as part of Federal Route 1. The first controlled-access highway segment, from Ipoh to Changkat Jering, was opened by the then Sultan of Perak, Azlan Shah on 28 September 1987. The expressway was completed on 5 February 1994 with the opening of the last segment from Juru to Changkat Jering and the opening ceremony for both this expressway and the south section was held on 8 September 1994. The order of construction came under criticism by observers because sections with low traffic were constructed first, while sections with heavy traffic were constructed last.
