rows into columns

Hi there,
I have a query that returns two rows per each license. What I need to do is to combine those two records into one.
the data looks like this:
AddressType       ATTN        Line1                     UNIT CITY                STATE     POSTALCODE    Country
Mailing Address ATTNTO      1234 SW 21 AVE      12      TOWNNAME      STATE      12345                  US
Site Address           ATTNTO      3456 SW 31 AVE            TOWNNAME      STATE     12345                  US

and I need the data like this:
Mailing AddressATTN       Mailing Address Line1    Mailing AddressUNIT  Mailing AddressCITY  Mailing AddressSTATE     Mailing AddressPOSTALCODE    Mailing AddressCountry  SiteAddressATTNTO SiteAddressTOWNNAME      SiteAddressSTATE ...
How can I do this?

here is the original query :
CASE WHEN ADDRESSTYPE = 'Mailing Address' then ADDREsSLINE1 else 
ADDRESSLINE1 + ' ' + isnull(PREDIRECTION,'') + ' ' + isnull(ADDRESSLINE2, '') + ' ' + isnull(STREETTYPE, '') END as Line1,
CASE WHEN UNITORSUITE <> '' then 'UNIT/SUITE: ' + UNITORSUITE else '' end as Unit
FROM BLAddresses

How do you know 2 address lines belong together?

EG:  If you have more than 2 rows, which combination go together?

Essentially you could do a self join:
select ma.AddressLine1, sa.AddressLine1 from 
Bladdresses ma
left join  Bladdresses sa on ma.CustomerID = sa.CustomerID and sa.AddressType ='SiteAddress'   --for demo only, use the key
where ma.AddressType = 'Mailing Address'

Good question there is a field that I didn't include it was LicenseNumber
Kyle AbrahamsSenior .Net DeveloperCommented:
So join on licensenumber . . . note that I changed the join to a full join so that you get all records:

select ma.*, sa.*
Bladdresses ma
full join  Bladdresses sa on ma.LicenseNumber = sa.LicenseNumber and sa.AddressType ='SiteAddress' 
where ma.AddressType = 'Mailing Address'
