Traffic on Rama II Road was briefly interrupted by a concrete spill during pouring for the M82 motorway being built overhead in Samut Sakhon early on Monday, not by a construction subsidence as some people had wrongly speculated on social media, the Department of Highways said.
The incident occurred about 1.55am at a construction site of the Ekkachai-Ban Phaeo section of the M82 project.
It was near kilometre marker 29+600 on the Bangkok city-bound lane of Rama II Road, a highway notorious for its decades of often-fatal accidents caused by the construction of the long delayed overhead motorway.
A Facebook user posted in a Samut Sakhon local news group that wet concrete had fallen onto the road surface as vehicles were passing. The post was quickly shared on social media, drawing complaints about the repeated construction-related accidents along the road.
In response, the Department of Highways apologised for the incident and said it happened during the pouring of concrete for a supporting cross beam.
Some of the mixed concrete had overflowed from a formwork into the protective trap and spilled onto the road below, blocking a traffic lane, the department said.
It was not caused by any structural flaw. The structure’s integrity remained safe.
Repair crews and machinery rushed to the scene by the department and the contractor quickly cleared away the spill and normal traffic resumed within 30 minutes, the statement said. There were no reports of people suffering any injury and no damage to public property, it said.
