Narrative:

Was told to cross runway 16L and hold short runway 16R at intersection J. After crossing runway 16L could not find the 'holding position marking.' seatac is in the process of redoing all the airport markings. I crossed and stopped just past what I thought was an old 'holding position marking.' this was actually the correct line. I stopped because I could see no line further on. No traffic conflict occurred but I was holding just past the line for landing traffic. I don't believe that intersection J is adequately marked.
