SQL Server sum of two varchar columns from their alias

I have a table as shown below

declare @Location Table([state] nvarchar(30) null,city nvarchar(30) null) Insert Into @Location Values('California','San Francisco') Insert Into @Location Values('California',null) Insert Into @Location Values('California','Orange County') Insert Into @Location Values('California',null)

And a select statement as shown below

select [state],city,[state] as CurrentState, case when city is null then 'Sacramento' else city end as CurrentCity from @Location

The output is as follows

I want a fifth column titled Address which gives me the sum of the columns CurrentState and CurrentCity Like thus:

Address California, San Francisco California, Sacramento California, Orange County California, Sacramento

Is this possible?

I've already tried CurrentState+', '+CurrentCity. It doesn't work
