The construction site starts from Bek Chan commune, Ang Snoul district in Kandal province to Bit Trang commune, Prey Nob district in Sihanoukville.

The project includes the expansion of the current road from 7m to 10m wide, renovation of 46 concrete bridges and drains, and construction of 8 new bridges.
