Transport Minister Jarupong Ruangsuwan revealed that Prime Minister Yingluck Shinawatra has ordered the Transport Ministry to urgently inspect all the roads throughout Bangkok which were flooded in 2011.
A sinkhole has recently been found on Chaengwattana Road. An official from the Department of Highways said the sinkhole was caused by the big flood in 2011.
The Ministry has assigned the Department of Highways to inspect other roads considered at risk of subsidence, including Ngamwongwan, Vibhavadi-Rangsit, Phaholyothin, Suwintawong, Petchkasem, and Rama 2 to ensure safety for commuters.
The authority is using ground-penetrating radar to see under the road surface and analyze information from the scans to find if there is any gap so that they can fix it before sinkholes develop.
