Constant motion

The Han River is a geographical, historical and cultural touchstone. While the river is no longer a trade route, cars and trucks trace its outline along the Gangbyeon Expressway on the river's north shore and the Olympic Expressway the south shore. Twenty-seven bridges cross the river within Seoul. Traffic is constant.  

This recording of the Gangbyeon Expressway was made underneath its eastbound lanes where it nips under the Seogang-daegyo (bridge).
