Narrative:

We were cleared to taxi from the ramp to runway 21L. I turned onto taxiway a and as we approached the runway 21R approach area I contacted ground and confirmed that we were cleared across the approach area. I taxied across some hold bars that I thought were for the runway 21R approach area; but realized about 20 ft later that they were for runway 21L. I immediately stopped the aircraft and asked tower for instructions. The tower stated that it was not a problem and cleared us for takeoff. Though I was looking at my commercial airport diagram; the convergence of many txwys and several red and white signs in that area on the taxiway led to my mistaking which hold bars I should have stopped at.

Narrative: WE WERE CLRED TO TAXI FROM THE RAMP TO RWY 21L. I TURNED ONTO TXWY A AND AS WE APCHED THE RWY 21R APCH AREA I CONTACTED GND AND CONFIRMED THAT WE WERE CLRED ACROSS THE APCH AREA. I TAXIED ACROSS SOME HOLD BARS THAT I THOUGHT WERE FOR THE RWY 21R APCH AREA; BUT REALIZED ABOUT 20 FT LATER THAT THEY WERE FOR RWY 21L. I IMMEDIATELY STOPPED THE ACFT AND ASKED TWR FOR INSTRUCTIONS. THE TWR STATED THAT IT WAS NOT A PROB AND CLRED US FOR TKOF. THOUGH I WAS LOOKING AT MY COMMERCIAL ARPT DIAGRAM; THE CONVERGENCE OF MANY TXWYS AND SEVERAL RED AND WHITE SIGNS IN THAT AREA ON THE TXWY LED TO MY MISTAKING WHICH HOLD BARS I SHOULD HAVE STOPPED AT.
