Sentence

The "Gold Rush" lasted, on and off, for, sixty or seventy years, then it finished.
Could you please tell me why there is a comma after 'for' in the above sentence? Is that necessary?

Thank you. By the way, is 'and' necessary there?

Yes, although often omitted in informal English.

'Then' is not a conjunction.
