Kien Giang, the province that is home to the island, the biggest in Vietnam and a top tourist attraction, recently approved the construction of the six-lane road on the western coast.
It will run between the Duong Dong River and Provincial Road 975B.
Also to be built are an embankment, drainage system, sidewalks, and a lighting system, and trees will be planted along the road.
The work will start in 2024 and take five years to complete.
Despite Phu Quoc's status as a tourist hotspot, there is an admitted dearth of infrastructure, especially coastal roads and public beaches near the center of Duong Dong town.
Most of its best beaches are inside resorts.
A report on Kien Giang’s official website on Dec. 14 said Phu Quoc attracted 5.4 million tourists this year, up 14.5% from the same period last year but only 90.7% of this year’s targeted figure.
They included 521,332 foreigners, a 211.3% increase and well above the target.
