THE WINGTIP OF A B777 HANGS OVER RWY 9L AT ORD DURING THE TURN FROM TXWY A TO TXWY C TO TXWY B.

Narrative

ACFT WAS PUSHED BACK FROM ORD WITH TAIL S. DEP RWY WAS RWY 32L WHICH REQUIRED A DOUBLE-BACK ON TXWY B TO GET TO RWY. TXWY B WAS BEING USED TO FEED DEPS TO RWY 4L SO TFC CONFLICTS EXISTED. GND CTL CLRED FLT TO TAXI TO RWY 32L VIA TXWY A-C-B AND THEN BACK TO ALPHA TO RWY 32L VIA TXWY A9. THE 180 DEG TURN FROM TXWY A TO TXWY C TO TXWY B REQUIRED OUR R WING TO VIOLATE THE CLRWAY FOR ORD RWY 9L. AS WE COMPLETED OUR TURN; IT APPEARED THAT AN RJ ACFT ON RWY 9L WAS GIVEN TKOF CLRNC. WE SPED UP TO QUICKLY REMOVE OUR WINGTIP FROM THE RWY ZONE AND THERE WAS NO PROB WITH ACFT SEPARATION AS THE TKOF ACFT HAD NOT APPEARED TO MOVE. IT WAS DISCONCERTING TO US SINCE WE KNEW OUR WING WOULD BE OVER THE RWY CLR LINE AND WE WERE NOT ON TWR FREQ TO DETERMINE THE DEPARTING ACFT'S ACTUAL CLRNC. WE EXPEDITED OUR TURN TO MINIMIZE EXPOSURE. GND CTL COULD HAVE AVOIDED THE CONFLICT BY CLRING US TO DOUBLE BACK VIA TXWY R RATHER THAN TXWY C. NO HUMAN FACTORS IN COCKPIT. WE WERE ALL FRESH AND AWAKE. THERE DID SEEM TO BE SOME IMPATIENCE IN TOE OF CTL FROM GND. ULTIMATELY; OUTCOME WAS NON EVENT; BUT COULD HAVE BEEN MORE COMPLICATED GIVEN OTHER CIRCUMSTANCES. 'UNCOMFORTABLE' SIT FOR CREW.
