For DNA data - the genetic human code - we know that the beginning of settlement of America happened at least 20.000 years ago.
The route that followed the first settlers:
The bridge or tunnel would provide a connection linking North America and South America and Asia.
Bering Strait:
Glaciation Process:
Glaciation allows to create a dry land route (Frozen Steppe)

According to a biologist to travel 13km annually is a medium average for a hunter who could travel that distance in one day looking for food.
