Korea Expressway Corporation operates the toll highways and service amenities en route. Korail provides train services to all major South Korean cities. Two rail lines, Gyeongui and Donghae Bukbu Line, to North Korea are being reconnected. The Korean high-speed rail system, KTX, provides high-speed service along Gyeongbu and Honam Line. Major cities have urban rapid transit systems. Express bus terminals are available in most cities.
  
  The main gateway and largest airport is Incheon International Airport, serving 58 million passengers in 2016. Other international airports include Gimpo, Busan and Jeju. There are also many airports that were built as part of the infrastructure boom but are barely used. There are also many heliports. The national carrier Korean Air served over 26 million passengers, including almost 19 million international passengers in 2016. A second carrier, Asiana Airlines also serves domestic and international traffic. Combined, South Korean airlines serve 297 international routes.
