Seremban–Port Dickson Highway, SPDH, , is an expressway in Negeri Sembilan, Malaysia. It was built to shorten the travelling distance from Seremban to Port Dickson and acts as an alternative route for Federal Route 53 which has dangerous corners along the route. The long expressway was opened to traffic in 1998 and the first concessionaries were Seremban–Port Dickson Highway (SPDH) Sdn Bhd (a member of Melewar Corporation Berhad). Today the expressway is a part of PLUS Expressways network. The expressway may be integrated into the Malacca Strait Bridge in the future.
