Bio-engineering work has been completed from Rugha upto Darke Khola in an area of 13,120 square metres where full widening along the Mugu Humla Link Road section was completed. Bio-engineering techniques like brush layering using branches of local plant species, covering 1433 running metre has been adopted. Similarly, 80kg of Ryegrass seed was sown at cut-and-fill slope area. Also, in order to stabilize fresh soil cut-and-fill slopes, 8 kg of millet was broadcast. The purpose of bio engineering work is to improve slope stability and prevent erosion of cut and fill slopes along the MHLR alignment.
