A CRJ200 CROSSING TUL RWY 18L/36R AT TXWY F WAS NOT TOLD OF NOR DID THE ARPT CHART SHOW THE TXWY REMOVAL E OF THE RWY. ACFT NEARLY TAXIED ONTO GRASS.

Narrative

ACFT REQUESTED TO CROSS ACTIVE RWY (18L) AND TAXI VIA TXWY E ON THE E SIDE OF RWY. THE ACFT WAS GIVEN INSTRUCTION TO CROSS RWY 18L AT TXWY F (AS REQUESTED). THE ACFT CONTINUED TAXI ACROSS THE RWY AT A DIAGONAL TO THE NE. BELIEVING THAT TXWY F CONTINUED AT A DIAGONAL ON THE E SIDE OF THE RWY THE PLT TAXIED AT A NORMAL SPD. UPON REACHING THE E SIDE OF RWY THE PLT NOTICED THAT TXWY F NO LONGER EXISTED ON THE E SIDE OF RWY 18L (BECAUSE IT WAS REMOVED DURING TXWY CONSTRUCTION IN AUG/SEPT 07). HE MADE A HARD L TURN TO REMAIN ON THE RWY THEN TAXIED APPROX 200-300 FT ON THE RWY TO TXWY C THEN EXITED THE RWY. I ASKED THE PLT IF HIS CHART SHOWED TXWY F CROSSING THE RWY ALL THE WAY ACROSS THE RWY THEN INTERCEPTING TXWY E ON THE E SIDE OF RWY 18L. HE REPLIED; 'YES; OUR MAP SHOWED FOXTROT CROSSING AT A DIAGONAL ALL THE WAY ACROSS.' I TOLD HIM THAT THE E SIDE OF F HAD BEEN REMOVED MONTHS BEFORE AND THAT A NEW CHART SHOULD ALREADY SHOW THAT. I ASKED WHAT DATE HIS CHART SHOWED HE REPLIED; 'DEC 07.' WHEN ASKED ABOUT THIS; THE ARPT OPS PERSONNEL SAID THAT THEY HOPE THAT THE ISSUE SHOULD BE RESOLVED BY APR 08. HAD THIS HAPPENED DURING POOR VISIBILITY OR DURING SLICK RWY/TXWY CONDITIONS; THE ACFT MAY HAVE ENDED UP IN THE GRASS JUST OFF THE ACTIVE RWY. THIS CONDITION WILL CAUSE A POTENTIAL HAZARD FOR POSSIBLY ANOTHER 5 MONTHS.
