Authorities of Phu Yen Province in south-central Vietnam have taken action to consolidate an eroded coastal dike to protect Tuy Hoa Airport.
Dang Khoa Dam, director of the management board of construction investment projects of Phu Yen, said on Saturday that his unit started building a sea embankment to protect Hung Vuong Street, which connects the eastern end of the seaside Tuy Hoa Airport with the province’s eponymous capital city.
The embankment will stretch 885 meters to prevent sea waves and high tides from rubbing the road.
The cost of the project is approximately VND150 billion (US$6.4 million).
Dam’s unit will strive to complete the new dike section before this year’s rainy season although its deadline is 2024.
“The erosion is so serious that unless we do it urgently and quickly, the consequences will be unpredictable when the stormy season comes,” said Dam.
Built about ten years ago to link Tuy Hoa City with Tuy Hoa Airport, which are some 11 kilometers apart, Hung Vuong Street is made of cement concrete, not asphalt concrete, as the authorities had foreseen coastal erosion.
Despite that, strong waves under the impact of climate change have washed away hundreds of meters of sand along the road over the years.
In 2019, the management board of construction investment projects of Phu Yen dumped thoursands of cubic meters of rocks along the road to fortify a 600-meter-long embankment that was damaged by waves.
In the past two years, sea waves have continued to erode Hung Vuong Street, washing away the roadbed’s sand layer, putting the road on the verge of collapse, and posing a direct threat to the safety of Tuy Hoa Airport.
