CAPT OF ACR MLG ACFT INADVERTENTLY CROSSED AN ACTIVE RWY TO WHICH TWR HAD ISSUED INSTRUCTIONS TO 'HOLD SHORT.'

Narrative

WE WERE TAXIING OUT OF THE RAMP AREA AT NIGHT FOR TKOF AND WERE CLRED BY GND CTL TO 'TAXI TO RWY 5R; TAXI W ON TAXIWAY R; HOLD SHORT OF RWY 36.' 10 SECONDS LATER; GND CTL SAID 'CLRED TO CROSS RWY 36; I HAVE AN SMA ACFT ON A 3 MI FINAL.' THEN A FEW SECONDS LATER 'TURN L ON TAXIWAY L.' I ACCELERATED TO CROSS RWY 36. IN REALITY L IS PRIOR TO RWY 36. GND CTL CAME BACK AND SAID 'HOLD YOUR POS.' I HAD MISSED THE L TURN ON L AND WAS NOW SHORT OF RWY 5R WHERE A TURBOPROP COMMUTER HAD JUST LANDED AND WAS MAKING HIS LNDG ROLLOUT AND WAS AT A FULL STOP ON RWY 5R. WE WERE BOTH FULLY STOPPED ABOUT 200 FT APART. THE PROBLEM AS I SEE IT IS A VERY CONFUSING INTXN WITH 2 XING RWYS AND 3 XING TAXIWAYS; ALL CONVERGING AT THE SAME SPOT. WHEN THE GND CTLR SAID HURRY UP CROSS RWY 36 AND TURN L ON L; THIS WAS ALSO CONFUSING BECAUSE L IS BEFORE RWY 36. IN MY RUSH TO CROSS RWY 36 BECAUSE OF LNDG TFC I INADVERTENTLY MISSED THE TURN TO L. POSSIBLE FACTORS: CONFUSING INTXN. 2 RWYS; 3 TAXIWAYS; NIGHT TIME AND MANY LIGHTS; AND A CONFUSING CLRNC TO HURRY ACROSS THE RWY. CORRECTIVE ACTIONS: I BELIEVE THAT A HOLD SHORT OF L CLRNC WOULD BE A LESS CONFUSING CLRNC. THEN CLARIFY THAT THERE IS LNDG TFC ON 36 AND 5R. THERE WAS A POTENTIAL FOR A RWY INCURSION EVEN THOUGH GND DID CATCH US BEFORE ANYTHING HAPPENED. THE 2 ACFT NEVER CAME CLOSER THAN 200- 300 FT.
