Pushpalal Highway (H18) (Nepali: पुष्पलाल लोकमार्ग (रा.१८), Puṣpalāl Lōkamārg (Rā.18))[1] is an ongoing road project in Nepal, which is thought to be 1,776 kilometres (1,104 mi) long. After completion, it will be the longest national highway of Nepal. Nepal has three geographical regions from east to west, plain land or Terai in south, higher mountains or Himalayas in north and hills in middle region. The highway runs through the mid-hills region only. It starts from easternmost hill at Chiyo Bhanjyang of Panchthar District (Koshi province ) and ends at westernmost hill at Jhulaghat of Baitadi District in far west (Sudurpashchim Province).[2][3]
