International road route on the island of Borneo

The Pan Borneo Highway , also known as the Trans Borneo Highway or the Trans Kalimantan Highway , is a road network on Borneo Island connecting two Malaysian states, Sabah and Sarawak, with Brunei and the Kalimantan region in Indonesia. The highway is numbered AH150 in the Asian Highway Network and as Federal Route 1 in Sarawak. In Sabah, the route numbers given are 1, 13 and 22. The highway is a joint project between both governments which started as soon as the formation of Malaysia in 1963 which comprised Malaya, Sabah, Sarawak and Singapore. The lack of a road network system in Sarawak was the main factor of the construction. The length of the entire highway is expected to be about for the Malaysian section, for the Bruneian section and for the Indonesian section. The Indonesian sections of the Pan Borneo Highway is known as the Trans Kalimantan Highway. The western route connects the city of Pontianak to Tebedu.

The Pan Borneo Highway, Asian Highway Route AH150 is supposed to be a circular highway that runs along the coastlines of Sabah, Sarawak, Brunei and Kalimantan. The Malaysian section of the Pan Borneo Highway is signposted as Federal Route 1 in Sarawak and Federal Routes 1, 22 and 13 in Sabah. By 1949, the Governor of North Borneo reported that there were 130 mile (209 km) of roads paved with asphalt, 23 mile (37 km) of other metalled roads, 225 mile (362 km) of dirt roads and 578 mile (930 km) of bridle paths. The construction of the intercity highway network in Sabah and Sarawak intensified at a faster pace after both states participated in the Federation of Malaysia in 1963. In Sabah, the first federally funded intercity highway project ever constructed was the Federal Route 22 from Kota Kinabalu to Sandakan, as a joint project between the Malaysian federal government with the government of Australia. Also dubbed as the "Malaysia Australia Road Project" (MARP), the construction of the FT22 highway began in 1968 and was completed in 1982 with Telupid town became the main centre of the project headquarters. In the meantime, the Kota Kinabalu–Papar section of the Federal Route 1 was completed in 1964, followed by the Kota Kinabalu–Kudat section which was completed in the 1970s. Meanwhile, in Sarawak, the construction of the first intercity trunk highway in Sarawak was commenced in 1965, dubbed as the "First Trunk Road". Most of the highway network in Sarawak was constructed within the decades of the 1960s to 1980s. However, the highway had not been fully paved with asphalt yet at that time; it was only by the end of Sixth Malaysia Plan (RMK6) in 1995 that the FT1 highway in Sarawak was fully paved. Those highways were later gazetted as a part of Asian Highway Network Route AH150. The Trans Kalimantan Highway (southern route) was completed in 2016 with the opening of the Tayan Bridge. Although some sections had been upgraded to divided highways, the Pan Borneo Highway was notorious for its poor condition in many sections. as of 2010, of the Indonesian Trans Kalimantan Highway was built below the Asian Highway Network Class III standards (lane width: 3.0 m; design speed limit: 80 km/h). A study to upgrade the entire highway to a super two highway under JKR R5 standard (design speed limit: 100 km/h; minimum lane width: 3.5 m) was done, which was expected to cost RM16 billion. The upgrade works of the Pan Borneo Highway to a divided highway is expected to be completed by 2023 for the Sarawakian section and by 2025 for the Sabahan section, with the overall cost of RM27 billion.

UEM, MMC and Warisan Tarang Construction Sdn Bhd is teaming up, forms UEM MMC Warisan Tarang JV Sdn Bhd via a joint venture (JV) and received their role as project delivery partner (PDP) via Borneo Highway PDP (BHP) Sdn Bhd in 2016. Warisan Tarang owns BHP. It starts at Sindumin and ends at Serudong. In 2019, UEM announces that UEM MMC Warisan Tarang JV Sdn Bhd agrees the WARISAN Pakatan Harapan government's decision to terminate their role as PDP. Since then, the joint venture company would gave up their operation and gives the project to other contractors to continue. This has caused the Sabah Pan Borneo Highway project to be disrupted in the long run until September 2020. In October 2020, new Sabahan government was established under GRS Party defeating Warisan Party in state election. The leaders of GRS Party announced that the Sabah Pan Borneo Highway will be restarted again and will not terminated the process until the Pan Borneo projects successfully done. In September 2023, The King of Malaysia, Yang di Pertuan Agong, Abdullah of Pahang visits Borneo Island (the journey also known as Kembara Borneo) and The King of Malaysia checking all the remaining Pan Borneo Highway projects. The journey began in Tawau, Sabah to Telok Melano, Lundu, Sarawak. The King's Kembara Borneo journey is aims to feel driving in the Pan Borneo Highway and also intended to known the Borneo more closer perspective.
