Collapse of Bangkok bridge ‘caused by water erosion’
A bridge that collapsed on Udom Suk Road on Saturday was likely undermined during ongoing construction work, according to Bangkok Governor Aswin Kwanmuang.
Aswin explained that a water-management building was being constructed nearby as part of the Nong Bon drainage tunnel project in the southeast of the city.
The bridge over Khlong Kled between Prawet and Bang Na districts was closed to traffic after it began collapsing around 4pm on Saturday. City officials and police blocked off access to the bridge as one lane slumped down, causing a large crack to open in the middle of the road.
Traffic police have diverted traffic onto alternative routes.
Road users travelling on the Udom Suk route to Srinakarin Road were instructed to turn left into Soi Udom Suk 51, while vehicles using the Bangna-Trat Road route were told to right into Soi Udomsuk 56.
Initial investigation indicated that water had leaked into a tunnel beneath the bridge, undermining its foundations and causing it to collapse.
