Cheonsa Bridge is a large sea bridge connecting Aphae Island and Amtae Island in Sinan. At 7.22 km long, it carries both a cable-stayed span and a suspension span on a single bridge, and it links onward to Jaeun Island, Anjwa Island and Purple Island. It opened on April 4, 2019, and as a motor-vehicle-only road it does not allow pedestrians, bicycles or two-wheeled vehicles. A section speed limit of 60 km/h means drivers cross it slowly.
