and pedestrian bridges, interchanges and bus shelters to the highway as part of a multi-phase project. A railway line existed before the war, but the last remnants of the line were dismantled in 1959. A rail project was announced in 2008 to be in line with the transport needs of SCORE, but as yet no construction work has begun despite an anticipated completion date in 2015. In 2017, the Sarawak government proposed a light rail system (Kuching Line) connecting Kuching, Samarahan and Serian divisions with anticipated completion in 2020. Currently, buses are the primary mode of public transportation in Sarawak with interstate services connecting the state to Sabah, Brunei, and Pontianak (Indonesia). Sarawak is served by a number of airports with Kuching International Airport, located south west of Kuching, being the largest. Flights from Kuching are mainly to Kuala Lumpur but also to Johor Bahru, Penang, Sabah, Kelantan, Singapore and Pontianak, Indonesia. A second airport at Miri serves flights primarily to other Malaysian states as well as services to Singapore. Other smaller airports such as Sibu Airport, Bintulu Airport, Mukah Airport, Marudi Airport, Mulu Airport, and Limbang Airport provide domestic services within Malaysia. There are also a number of remote airstrips serving rural communities in the state. Three airlines serve flights in Sarawak, Malaysia Airlines, Air Asia, and MASwings all of which use Kuching Airport as their main hub. The state owned Hornbill Skyways is an aviation company that largely provides private chartered flights and flight services for public servants. Sarawak has four primary ports located at Kuching, Sibu, Bintulu, and Miri. The busiest seaport at Bintulu is under the jurisdiction of the Malaysian federal government and mainly handles LNG products and regular cargo. The remaining ports are under the respective state port authorities. The combined throughput of the four primary ports was 61.04million freight weight tonnes (FWT) in 2013. Sarawak has 55 navigable river networks with a combined length of . For centuries, the rivers of Sarawak have been a primary means of transport as well as a route for timber and other agricultural goods moving downriver for export at the country's major ports. Sibu port, located from the river's mouth, is the main hub along the Rajang River mainly handling timber products. However, the throughput of Sibu port has declined over the years after Tanjung Manis Industrial Port (TIMP) began operating further downriver. Healthcare Health care in provided
