Narrative:

Some confusion with similar call signs. I believe ground control gave us wrong turn out. We were cleared to taxi to runway 32R via right turn, outer, outer bridge to runway 32R. Turning right on outer, didn't involve crossing any bridge. Both pilots were looking at taxi chart to figure what was ambiguity of clearance (we should have been cleared to turn left on outer). Nose of aircraft crossed runway 9R hold short lines, but didn't enter runway as I looked up and braked. Missed turn onto parallel. Also, I won't taxi until I fully understand the taxi route.

Title: CAPT OF AN MLG ACR ACFT INADVERTENTLY TAXIED OVER ACTIVE RWY 'HOLD SHORT' LINE DURING TAXI FOR TKOF.

Narrative: SOME CONFUSION WITH SIMILAR CALL SIGNS. I BELIEVE GND CTL GAVE US WRONG TURN OUT. WE WERE CLRED TO TAXI TO RWY 32R VIA R TURN, OUTER, OUTER BRIDGE TO RWY 32R. TURNING R ON OUTER, DIDN'T INVOLVE XING ANY BRIDGE. BOTH PLTS WERE LOOKING AT TAXI CHART TO FIGURE WHAT WAS AMBIGUITY OF CLRNC (WE SHOULD HAVE BEEN CLRED TO TURN L ON OUTER). NOSE OF ACFT CROSSED RWY 9R HOLD SHORT LINES, BUT DIDN'T ENTER RWY AS I LOOKED UP AND BRAKED. MISSED TURN ONTO PARALLEL. ALSO, I WON'T TAXI UNTIL I FULLY UNDERSTAND THE TAXI RTE.
