The ministry said in a statement released on Monday that the construction and improvement of NR4 starts from Bek Chan commune, Ang Snuol district, Kandal province to Bit Trang commune, Prey Nup district, Preah Sihanouk province.

The project officially started in December 2021 and is scheduled for completion in December 2026, the ministry added.

According to the ministry, the construction and improvement of NR4 includes the expansion of the current road from 7 to 10 meters wide, the improvement of 46 concrete bridges and drains, and the construction of eight new bridges to ensure traffic and resilience to flood.

The NR4 stretches over 230 kilometers, linking the capital and the deep seaport in Preah Sihanouk province. The road was built during the 1950s as a legacy of the relationship between Cambodia and the United States.

Currently, the government is building the country’s first ever 190-kilometer Phnom Penh-Sihanoukville expressway. The road is scheduled to put into temporary use in upcoming July.
