Trans-Sumatra Highway

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). Upgrade work is expected to begin in March 2013 transforming it into a full-fledged highway, including land acquisition. The road is a major artery, carrying transmigrants from Java to the less densely populated Sumatra, and carrying Sumatran visitors to Jakarta and Java. The eastern and central route of the Trans-Sumatra Highway forms the whole section of the Asian Highway 25 (AH25) and ASEAN Highway 151 (AH151), respectively. It consists of 4 parts, namely Jalan Raya Lintas Barat (Jalinbar), Jalan Raya Lintas Tengah (Jalinteng), Jalan Raya Lintas Timur (Jalintim), and Jalan Raya Lintas Pantai Timur. Parts of it are being set up for controlled-access highways. The Medan–Binjai Toll Road is 17 km long and set to completed in the end of 2017. On 6 May 2026, a major accident took place along the highway between a bus and an oil tanker, resulting in 16 deaths.
