A clip shared online by a rescue worker shows the aftermath of the collapse, with sirens blaring as shocked residents and bystanders survey the damage.
The wrecked girder – and much of the under-construction highway it also brought down – can be seen blocking the street.
Rescue workers swarmed over the debris, with crushed vans and cars just visible. As night fell, rescuers could still be seen among the rubble.
Thailand has a poor construction safety record, with accidents a common occurrence.
In 2016, at least 13 people died after a building caved in during construction.
The incident brought renewed protest from labour groups, who had long warned about lax safety standards and low wages at Thai construction sites.
