00:00Who would have thought a coastal road gets built this way?
00:02The first step isn't building the road, it's creating land.
00:04Coffer dams are placed directly into the sea, blocking seawater out, then every drop inside
00:08is pumped dry.
00:09What was ocean surface becomes a construction site instantly.
00:12Now the real foundation work begins.
00:14Several excavators are crane-lifted in and start digging pure foundation pits.
00:17Once four pits are formed, prefabricated concrete caissons are immediately lowered in.
00:21This step essentially locks the entire road's weight deep into the seabed.
00:24If it sinks, the road fails.
00:26These caissons transfer low down to stable rock layers while simultaneously resisting
00:29long-term seawater erosion, because no matter how smooth the road surface above, the foundation
00:33gets hollowed out from below without proper protection.
00:35Construction vehicles then pour in large volumes of crushed stone, compacted layer by layer.
00:39This isn't simple filling, it's building an isolation layer that completely separates
00:42reinforced concrete from seawater, slowing corrosion and extending the structure's lifespan.
00:46Concrete is then poured and left to cure slowly, locking the structure together.
00:50Once full strength is reached, the surrounding cofferdams are removed.
00:53For bridge piers stand directly exposed in open sea, already completely stable.
00:57Upper structure continues upward, formwork and steel plates are installed above the piers.
01:01Concrete poured again, cured, formwork removed.
01:03Both sides of the structure are locked together as one unified piece.
01:06Only then comes the road surface.
01:08Concrete poured across the entire span, then asphalt-laden lane markings painted once fully
01:12connected.
01:12What looks like just a road surface is actually a complete system fighting ocean waves underneath.
01:16Whether a bridge stands permanently depends not on surface construction,
01:19but on what's buried in the water below.
