Persiaran Senawang 1

Persiaran Senawang 1 (English: Senawang Boulevard 1), designated as Malaysia Federal Route 242, is a dual-carriageway federal road in Seremban, Negeri Sembilan, Malaysia. Linking Paroi and Senawang, this dual-carriageway serves as the bypass of the Seremban city centre to Kuala Pilah and vice versa. This dual-carriageway may also provide a direct link between the North–South Expressway Southern Route and the Kajang–Seremban Highway. The Kilometre Zero of the Federal Route 242 is at Paroi.
