SMT AIR TAXI CROSSES ACTIVE RWY WITHOUT CLRNC WHEN TAXIING.

Narrative

ACFT WAS CLRED TO TAXI FROM LAKE HOOD TXWY V TO RWY 6L AT TXWY R FOR DEP ON RWY 6L AT TXWY R. AS I APCHED TXWY K ON TXWY R THE AUTO-TRIM ANNUNCIATOR AND CHIME ACTIVATED. AS I LOOKED AT THE CIRCUIT BREAKER PANEL TO RESET THE TRIM SYS I CROSSED TXWY K; GLANCED TO MY L AND MISTOOK IT FOR TXWY L. I THEN CONTINUED ACROSS RWY 6L MISTAKING IT FOR TXWY K. AS I STOPPED AT THE HOLD LINE FOR RWY 6L I REALIZED I WAS ON TXWY G AT RWY 6R. AT THIS TIME GND CTL INFORMED ME THAT I HAD CROSSED RWY 6L. THEY THEN CLRED ME TO CALL TWR. TWR INITIALLY HAD ME MAKE A L TURN TO RETURN TO RWY 6L IN POS FOR TKOF. TWR THEN INFORMED THERE WAS A SPECIAL VFR INBOUND AND ASKED IF I WOULD ACCEPT RWY 24L; AT TXWY G FOR TKOF WITH 6000 FT REMAINING. I THEN MADE A 180 DEG TURN ON RWY 6L THEN A L TURN TO GET ON RWY 24L FOR TKOF. ALTHOUGH I HAVE USED THIS RTE TO RWY 6L AT TXWY R MANY TIMES IN THE PAST; RECENT TXWY CHANGES HAVE BEEN MADE AT ANC. TXWY G HAS BEEN MOVED BTWN RWY 6L AND TXWY K; A SHORT DISTANCE E. ALSO; TXWY R NOW GOES STRAIGHT ACROSS RWY 6L TO INTERSECT TXWY G AT RWY 6R. TXWY R PREVIOUSLY HAD A R DOGLEG TURN BTWN TXWY K AND RWY 6L THEN STOPPED AT RWY 6L. THE CURRENT ARPT DIAGRAM STILL SHOWS PREVIOUS TXWY ALIGNMENT. I FEEL THIS INCIDENT WAS CAUSED BY MY DISTR WHILE TAXIING AND TRYING TO TROUBLE- SHOOT THE TRIM MALFUNCTION LIGHT AT THE SAME TIME. PREVIOUS EXPERIENCE AT MAKING THE R DOGLEG TURN THEN STOPPING AT RWY 6L CAUSED ME TO CONTINUE ACROSS RWY 6L AS IT NOW GOES STRAIGHT AND I WAS NOT PAYING DILIGENT ATTN TO MY SURROUNDINGS.
