Gwangan Bridge

This guide to Gwangan Bridge in Busan opens with a question about the patched steel deck under its lower roadway, then rewinds to a February afternoon in 2019, when a Russian cargo ship called the Seagrand pulled out of Busan's harbor bound for Vladivostok, drifting off its cleared shipping lane while coast guard radio calls went unanswered. It follows the chase that followed, as patrol boats forced the ship back into port, and the questions investigators had to untangle about who was actually at the controls. By night the same bridge glows with LED lights that earned it the nickname Diamond Bridge.
