Gohain Kamal Ali, was a road that connected the capital of the Koch kingdom and Narayanpur in Lakhimpur district in Assam. This was constructed under the supervision of Gohain Kamal, the step-brother of Nara Narayan the king, and was completed in 1547. This was the road that the Koch general Chilarai used soon after for his invasion of the Ahom kingdom, and attacked the Ahom fort at Pichala, which was not a success, but a later movement in 1562 was greatly successful.
