These are pics of the expo bridge in Daejeon city. At night, there’s a light show utilizing the LEDs placed alongside the bridge’s structure, creating a huge running LED. The running LED shows different images, starting from simple lines, heart shapes, light house, to a writing in Hangeul.
This photo is taken from a platform located at the side of the Gapcheon river. If you go night riding, make sure to stop by and enjoy the lightshow along with the beautiful reflection on the water surface. Note: I don’t know whether they show this every night or not.
