AN ACR PILOT INCURSED CWA RWY 17 TAXIING TO RWY 8. HEAVY SNOW AND DE-ICE FLUID IMPAIRED VISIBILITY. SNOW COVERED RWY SIGNS AND HOLD SHORT LINE.

Narrative

TAXI AFTER DEICE FOR DEP ON RWY 8. VISIBILITY FROM FLT DECK POOR DUE TO DEICE AND ANTI-ICE ON WINDSHIELDS; AND SNOW BLOWING SNOW. MISSED THE HOLD SHORT LINE FOR RWY 8 DUE TO SNOW COMPLETELY COVERING THE SIGNS AND MARKINGS. RWY 17 WAS COMPLETELY SNOW COVERED WITH NO RWY MARKINGS VISIBLE; MOREOVER THE RWY LIGHTS FOR RWY 17 WERE COVERED WITH SNOW. I REALIZED THAT I HAD TAXIED ON THE CLOSED RWY 17 AT THE SAME TIME THE TWR NOTIFIED US OF MY MISTAKE. THE TWR SAID THAT THERE WAS NO PROB AS RWY 17 WAS CLOSED. TO ADD FURTHER INFO; THE COMMERCIAL CHART DOES NOT DEPICT A HOLD SHORT POINT. SNOW OBSCURING SIGNS AND MARKINGS; TAXI CHART INCOMPLETE; AND SNOW OBSCURING THE RWY LIGHTS FOR THE CLOSED RWY 17. IT WASN'T UNTIL I HAD REACHED THE FAR W END OF THE TXWY; THAT I REALIZED I HAD TAXIED ONTO THE CLOSED RWY AND THEREFORE PAST THE HOLD SHORT LINE FOR RWY 8. NO ACTION TAKEN. ATC INSTRUCTED US TO HOLD OUR POS; AND THERE WAS NO PROB. I THINK THAT ATC COULD HAVE ISSUED A CAUTION; THAT WOULD HAVE GIVEN US MORE INSIGHT.
