via Khmer Times, 13 August 2020: Part of the ongoing restoration of the Angkor Wat causeway.
The drainage system beneath Angkor Wat temple’s ancient bridge has been fixed, the Apsara National Authority said yesterday, with the rest of the revamping still underway and expected to conclude in the next two years.
The maintenance of the bridge drains was done to prevent any instance of erosion damage beneath the structure after water was found trapped within the pipes.
In a statement released by the ANA, it said the clogging of the drain pipes were due to the presence of plastic and soil inside.
