The Hangang River, which runs throughout Seoul, has 27 bridges crossing its span including both road and railway bridges. Two smaller rivers from the mountains to the east of the country join together to form the Hangang river, which is the country’s fourth largest of its kind and provides water for over 12 million citizens. Most of the bridges’ lights are turned on from sunset to 11pm, but are operated flexibly depending on the season and other circumstances.
