beam bridges
piles by the sea
Sea bridges are made by inserting a large hallow pipe deep into the sea. The water which is already present is pumped out. Thus a gap is created by displacing the water. This gap is filled with structures/pillars/columns etc.
so they could cross over the sea

The disappearance of land bridges was primarily caused by rising sea levels during interglacial periods, such as the end of the last ice age. As temperatures increased, glaciers melted, causing the sea levels to rise and submerge the land bridges that once connected continents. Additionally, tectonic activity and shifting landmasses may have played a role in the disappearance of some land bridges.
It is the longest big-ship ( as opposed to sub-sized barges) canal of its type in the World. It is a sea-level canal and does not require locks. it had movable bridges for traffic control at one time- but these were not, strictly speaking, hydraulic locks.
The land of dry deserts that bridges two continents is Beringia. This land connects America and Asia through Siberia and Alaska.
