Bridges is the plural form of bridge.
Land bridges were explanations for how animals and plants might have migrated between continents, particularly during periods of low sea levels when land connections existed. These land bridges provided pathways for species to disperse and colonize new areas.

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.
The land of dry deserts that bridges two continents is Beringia. This land connects America and Asia through Siberia and Alaska.

Land bridges
Land bridges aren't actually formed, they are already there but covered by the sea. When a glacial period starts, the water evaporated from the oceans falls as snow on the land and then compacts as ice which does not melt. Continual removal of water from the oceans over thousands of years causes sea level to drop and exposes the "land bridges".
