The incident took place at 9:15 a.m. on the Bangkok-bound lane near kilometer marker 34, also known as Debaratna Road. According to traffic reports, an 18-wheeler dump truck had raised its cargo carrier, which hit the overhead pedestrian crossing, causing a section of the structure to give way.

The collapsing concrete landed on the front of the dump truck and directly onto a pickup truck traveling beside it. The pickup, which was carrying eggs, was crushed, and its 59-year-old driver was pronounced dead at the scene by rescue workers from the Ruam Katanyu Foundation.

The 65-year-old dump truck driver sustained minor injuries and was taken to a nearby hospital for treatment. Police have detained him for questioning and indicated he will face charges related to the incident.

Two large cranes were brought in to clear the wreckage from the road, and traffic was disrupted for approximately three hours before normal flow could resume.

Highways Department director Piyapong Jiwattanakulpaisarn stated that the damaged section measured about 16 meters in length. He explained that while the pedestrian bridge was designed to withstand vertical loads, it could not endure the lateral impact from the truck. The overpass, originally built at a cost of around 10 million baht, will now be inspected by civil engineers to determine whether it must be fully demolished and replaced.
