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".
