embankment

Footage showed the mangled wreckage on an embankment on the side of the highway.

National Highways has promised that 80% of the crossing will run through either a tunnel, cutting or embankment to blend it into the landscape.

Authorities believe that the Subaru had left the roadway and overturned several times down an embankment.

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.
