The Koshi Barrage is a sluice across the Koshi river that carries vehicular, bicycle, and pedestrian traffic between Saptari district and Sunsari district of Nepal. It is near the International border with India. It was built between 1958 and 1962 and has 56 gates. It was constructed after the Koshi Agreement was signed between the Government of Nepal and India on April 25, 1954. The barrage was designed and built by Joseph and Company Limited, India. The Koshi Tappu Wildlife Reserve is roughly 3–4 miles north of the barrage. From Wikipedia
