I didn't realize how large a river the Han was until I saw rivers in other countries. Like the first time I saw the Seine. 'That's a river????', I thought. It looked like what we Seoulites would call a brook or a stream. You could cross it on foot in 15 minutes or less, whereas I don't think anyone in their right mind would cross the Han by walking, as it'll probably take 40 minutes to an hour.
(I miss the Seine. Crossing a river on foot seems like a quaint luxury, now.)
The Han is flanked by highways on each bank, the 88 Olympic highway to the south and Gangbyeonbukro (literally, North Riverbank Highway) to the north. This clip was taken on Gangbyeonbukro from a bus on a cloudy day, traveling west to east.
