History
Route Coloniale 19 or RC19 was constructed by the French in the early 20th century and was the main road connecting the Central Highlands with the coastal region of Vietnam.
The Battle of Mang Yang Pass took place along RC19 between An Khê and Pleiku from 24 to 30 June 1954.

As part of the Battle of Ban Me Thuot in March 1975, the NVA blocked Route 19 preventing the movement of ARVN reinforcements towards Pleiku and preventing its use in the subsequent evacuation of the Central Highlands.
