The Koshi River is the largest river in Nepal, and also the most historical.  The Koshi Barrage was built in 1958 as a flood control sluice with the help of India.  The Barrage is a part of the East-West Highway that runs through most of Nepal.  As a result, a lot of heavy cargo truck and passenger buses are found to be going through this barrage everyday.
