Can you give an example? It's possible there may be an alternative solution.

bigint Range : -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807)
Ur Data Cross this Range or what..?

I have to ask, what kind of data are you putting into the primary key? If it is an auto-incrementing identity, then the chances of exceeding the size of BigInt are remote. However, if the size of the table does get big enough to exceed BigInt, the easiest way around that is to create a new table and store more data there.

You could consider using a GUID instead of a number. There are a few more combinations for a GUID vs. bigint... It'll take more space. Also, like the comments above, bigint has a HUGE range, I doubt you'll run out any time soon.

As an additional consideration, consider archiving your data to history tables if it gets that big.
