BNSF Latah Creek ( Spokane ) bridge

Hi all

Can someone tell me the date that the .subject became operational? Have a article in google.groups about this ( Curved Bridge ) but I can not for the life of me remember when the bridge was completed and the first revenue ran across it.

thanks in advance
