Gyeongin Expressway

The Gyeongin Expressway (Gyeongin Gosok Doro (경인 고속 도로; 京仁高速道路) or Gyeonginseon (경인선; 京仁線; "Gyeongin Line") for short in Korean) was the second freeway to be built in South Korea, and connects Seoul to Incheon. Before being upgraded to a freeway, this highway--built in 1968--was the first modern, 4-lane highway in South Korea. It became a freeway in the 1970s and was given the route number 2, but was more recently renumbered to 120. As with all freeways in South Korea, the Gyeongin is a toll highway.
