TXWY INCURSION WHEN THE FLC OF A TAXIING B727-200 TAKES TXWY THAT HAD BEEN ATIS'ED CLOSED AT ATL; GA.

Narrative

WE HAD JUST LANDED ON RWY 8L IN ATL AND WERE IMMEDIATELY CLRED TO CROSS RWY 8R. WE EXITED RWY 8L AT TXWY B7 AND WERE CLRED TO CROSS RWY 8R AT TXWY D. THE GND CTLR ADDITIONALLY CLRED US TO MAKE A R TURN ON TXWY E AND TAXI TO THE RAMP. THE CAPT TOOK CTL OF THE ACFT ON TXWY B7 AND EXPEDITIOUSLY TAXIED ACROSS RWY 8R AT TXWY D; BUT THEN CONTINUED ON TO MAKE A R TURN ON TXWY F. AS WE BEGAN THE TURN ON TXWY F; GND INFORMED US THAT TXWY F WAS CLOSED. AT THIS POINT; WE WERE UNABLE TO TURN AROUND; SO GND CLRED US DOWN TXWY F. WE WERE SUBSEQUENTLY TOLD THAT TXWY F WAS NOW OPENED. UPON HEARING THAT TXWY F WAS CLOSED; I LOOKED UP FOR THE FIRST TIME SINCE I WAS COMPLETING THE AFTER LNDG FLOW/CHKLIST AND SETTING THE RAMP FREQ. WHAT CAUSED THE INCURSION? UNDER NORMAL CONDITIONS; THIS SHOULD NOT HAVE BEEN AN ISSUE AT OUR HOME FIELD. THE SO COPIED THE ATIS AND INFORMED US THAT TXWY F5 WAS CLOSED. HE LATER COMMENTED THAT THE COMPUTER GENERATED VOICE IS HARD TO UNDERSTAND AT TIMES AND TXWY F MAY HAVE BEEN ON THE ATIS. WE DO NOT HAVE ACARS. ADDITIONALLY; THE CLOSURE WAS NOT ON THE NOTAMS WE RECEIVED WITH OUR FLT PLAN IN LOUISVILLE. ANOTHER FACTOR IS THE NORMAL PACE OF EVENTS IN THE AFTER LNDG PHASE IS VERY HIGH AT A MAX CAPACITY MAJOR HUB. THIS PACE IS NORMALLY SLOWED BY A BRIEF STOP WHILE HOLDING SHORT OF RWY 8R. ON THIS MORNING; WE DID NOT HAVE THE STOP. EXPECTATIONS ALSO IMPACTED THE CAPT'S ACTIONS. THE TYPICAL FLOW AT ATL WOULD HAVE INBOUND TFC TAXI IN ON TXWY F. FINALLY; THERE WAS NO PHYSICAL BARRIER OR LIGHTS TO INDICATE THE CLOSURE OR ANY ADDITIONAL WARNING FROM GND TO NOT EXPECT SOMETHING OUT OF THE ORDINARY. AS THE FO; I READ BACK GND'S INSTRUCTIONS TO USE TXWY E AND THOUGHT THE CAPT HEARD IT TOO. I THEN LEFT MY FAITH IN HIM TO TAXI CORRECTLY AND HAD NO REASON TO BELIEVE HE WOULD HAVE DIFFICULTY TAXIING AT OUR MOST FAMILIAR FIELD. SO; I THEN DIRECTED MY ATTN TO THE AFTER LNDG FLOW AND RAMP FREQ. UNFORTUNATELY; I THINK THE CAPT AND I BOTH CLRLY HEARD THE 'E' VICE 'F;' BUT COMPREHENDED WHAT WE EXPECTED TO HEAR.
