양수대교

This is Yangsoo Bridge (양수대교, 兩水大橋), a truss bridge that spans across the North Han River. This is also the same bridge that appears in Hotel del Luna as the 'Sandocheon bridge' (삼도천 다리, 三途川橋) - a bridge spirits have to cross to transit from 'this world' to 'the other world'. The bridge may seem like CGI in the drama but it is real and located at Yangpyeong.
