I was wondering whether more exposed land would have made much difference to migration routes?
The DNA record doesn't show any migrations across the north or south Atlantic Ocean, correct? Is there any evidence of humans using routes other than the Bering Strait?

What was the sea level at 20K years ago?

Quite low. In fact around 20,000 years ago during the last glacial maximum (LGM), sea level was around 130 meters lower than current day.
