NH12 or Sunkoshi Corridor (Nepali: सुनकोशी करिडोर) or Ghurmi-Regmitar-Barkhadada road is a National Highway that runs through the Hills of Udayapur District, Bhojpur District and Khotang District of Koshi Province, Nepal. It is currently under construction. The total length of the highway is calculated to be 163 kilometres (101 mi).[1][2] The highway starts at Ghurmi (Udayapur) being separated from NH03 and runs parallel to the Sunkoshi River until Thanagaun (Tapli Rural Municipality) before it crosses the Sunkoshi river and enters into Khotang District. It then runs parallel to the Sunkoshi River again until it reaches Regmitar. The highway then crosses NH16 at Regmitar (Rajapani). The highway continues on to Damarkhu where it crosses the border of Khotang District and enters into Bhojpur District. This section of road runs in the Aamchowk Rural Municipality of Bhojpur District before it crosses the Sunkoshi River again and enters into Udayapur District again at Ranitar of the Chaudandigadhi Municipality then moves east and enters to Belaka Municipality. It finally merges with NH03 at Barkhadanda near Chatara Koshi bridge.
