RWY INCURSION. RWY WAS ACTIVE.

Narrative

WE WERE CLRED TO LAND ON RWY 14 AT ANC ON A WET AND RAINY NIGHT. ON FINAL WE REQUESTED TO ROLL TO THE END. WE WERE CLRED TO ROLL TO THE END AND TAXI TO OUR GATE. WHILE ROLLING OUT; WE NOTICED THAT THE RWY GETTING VERY DARK AT END. SIGN FOR TXWY M WAS LIT BUT TXWYS L AND K WERE NOT (RWY CONSTRUCTION HAD BEEN GOING ON FOR 2 MONTHS AND THE CTLR TOLD US ON PHONE THAT IT WAS JUST OPENED TONIGHT). RWY TERMINATING BARS WERE ALWAYS AT END OF RWY ON TXWY K. WE FOUND OURSELVES TAXIING TO RWY TERMINATION BARS BUT CONSTRUCTION PUT THEM ON FAR SIDE OF RWY 6L (ACTIVE RWY). ACFT ON FINAL WAS INSTRUCTED TO GAR AS WE WERE APCHING TXWY K (OR WHAT WE THOUGHT WAS TXWY K -- IT WAS RWY 6L). THERE WERE NO LIGHTS ON RWY AT FAR END. IT WAS VERY DARK AND DRIZZLY. THIS COULD HAVE BEEN A REAL DISASTER. SUPPLEMENTAL INFO FROM ACN 316948: RWY 14/32 HAS BEEN UNDER CONSTRUCTION FOR THE PAST 2 MONTHS. THE FIRST 800 FT OF RWY 32 HAS BEEN CLOSED WHICH INCLUDES THE INTXN OF TXWY K. PRIOR TO CONSTRUCTION; RWY 32 APCH END TERMINATED ADJACENT TO TXWY K. CONSTRUCTION COMPLETE SEP/AA/95 (HRS BEFORE WE LANDED). NO RWY LIGHTS EXIST AFTER TXWY K!
