Following the crash, it emerged that an operating manual from Muan International Airport, uploaded early in 2024, had said the concrete embankment was too close to the end of the runway.

Structural maintenance includes resurfacing and reconstruction of roads and footways, as well as investment in both drainage infrastructure and in the structural stability of embankments.

The driver was an older person who lost control of their vehicle on a nearby embankment and had minor injuries, said watch commander Lt.

The inquest heard Hugo lost control after taking the bend too fast, entered on to a grass verge, went down a steep embankment and then into a water-filled drainage ditch.

A "complex repair operation" has begun to fix a motorway bridge after a lorry left the carriageway and fell on to an embankment below, authorities have said.
