In 1989, parts of Gyeyang town were ceded to Incheon, giving Incheon a border with southwestern Seoul. And 1995, Geomdan region was ceded to Incheon. In 1998, Gimpo was promoted to a city. Since the Hangang New Town was announced in 2003, the population of the city has soared. Gimpo Light Rail was opened in 2019 for the sake of population growth and the convenience of transportation in the new Han River city. This line connects Yangchon Station and Gimpo Airport Station, which is a two-car light-rail line. In response, some citizens are demanding more cars or extension of Seoul Subway Line No. 5 in preparation for the soaring demand for transportation in the future.
