The Trans-Sumatra Highway (Indonesian: Jalan Raya Trans-Sumatra) is a primary north–south road in the Indonesian island of Sumatra, 2,508.5  km in length, and connecting the northern island at Banda Aceh to Bandar Lampung in the south, running through many major cities, traversing Medan, Pekanbaru, Jambi, and Palembang along the way (Sumatra East Road).
