Narrative:

Captain landed from ILS approach in driving rain with a strong crosswind. During approach captain tried wind shield wipers, but decided visibility was as good west/O them and secured them. Though conditions were demanding, landing was uneventful. Before exiting runway, tower instructions were, 'left on alpha, right on the inner, taxi to the gate, stay with me.' copilot rogered instructions but did not read back. After exiting the runway, I was going through the after landing flow and resetting the trim when I felt a thump-thump. At first the nose gear and then the mains went over a 3' lip of unfinished pavement on the closed outer taxiway. Captain had not copied clearance to taxi via the inner and had turned onto the outer as would be the normal route inbound. Only the top portion of pavement was not laid down, so the weight of the aircraft was supported. A tug was called, pushed us back and towed us to the gate. No damage was done. Relevant factors and observations: immediately after accomplishing a physically demanding task there is a tendency to not fully register everything that is said to you. Also, after accomplishing a demanding approach and landing, there is a tendency to momentarily let your guard down and think the worst is over, 'we're safely on the ground.' tower controller should never issue taxi instructions while aircraft is still on the runway. Copilot could have further alerted captain by reading back clearance, or just by repeating that the outer was closed and not assuming he was aware. A row of unlit cones was all that blocked the portion of the taxiway we taxied onto (there were approximately 7-8 cones, and only the ones on the edge of the taxiway had dim flashing lights in line with the other taxiway lights and not highly visible). Due to rain on the wind shield and brighter background lights, none of these markings were sufficiently visible or alerting. Under conditions of low visibility, when known obstructions exist on surface, copilot's attention is better directed outside rather than immediately jumping into the after landing items.

Title: ACR WDB TXWY EXCURSION AFTER LNDG AT JFK.

Narrative: CAPT LANDED FROM ILS APCH IN DRIVING RAIN WITH A STRONG XWIND. DURING APCH CAPT TRIED WIND SHIELD WIPERS, BUT DECIDED VISIBILITY WAS AS GOOD W/O THEM AND SECURED THEM. THOUGH CONDITIONS WERE DEMANDING, LNDG WAS UNEVENTFUL. BEFORE EXITING RWY, TWR INSTRUCTIONS WERE, 'LEFT ON ALPHA, RIGHT ON THE INNER, TAXI TO THE GATE, STAY WITH ME.' COPLT ROGERED INSTRUCTIONS BUT DID NOT READ BACK. AFTER EXITING THE RWY, I WAS GOING THROUGH THE AFTER LNDG FLOW AND RESETTING THE TRIM WHEN I FELT A THUMP-THUMP. AT FIRST THE NOSE GEAR AND THEN THE MAINS WENT OVER A 3' LIP OF UNFINISHED PAVEMENT ON THE CLOSED OUTER TXWY. CAPT HAD NOT COPIED CLRNC TO TAXI VIA THE INNER AND HAD TURNED ONTO THE OUTER AS WOULD BE THE NORMAL RTE INBND. ONLY THE TOP PORTION OF PAVEMENT WAS NOT LAID DOWN, SO THE WEIGHT OF THE ACFT WAS SUPPORTED. A TUG WAS CALLED, PUSHED US BACK AND TOWED US TO THE GATE. NO DAMAGE WAS DONE. RELEVANT FACTORS AND OBSERVATIONS: IMMEDIATELY AFTER ACCOMPLISHING A PHYSICALLY DEMANDING TASK THERE IS A TENDENCY TO NOT FULLY REGISTER EVERYTHING THAT IS SAID TO YOU. ALSO, AFTER ACCOMPLISHING A DEMANDING APCH AND LNDG, THERE IS A TENDENCY TO MOMENTARILY LET YOUR GUARD DOWN AND THINK THE WORST IS OVER, 'WE'RE SAFELY ON THE GND.' TWR CTLR SHOULD NEVER ISSUE TAXI INSTRUCTIONS WHILE ACFT IS STILL ON THE RWY. COPLT COULD HAVE FURTHER ALERTED CAPT BY READING BACK CLRNC, OR JUST BY REPEATING THAT THE OUTER WAS CLOSED AND NOT ASSUMING HE WAS AWARE. A ROW OF UNLIT CONES WAS ALL THAT BLOCKED THE PORTION OF THE TXWY WE TAXIED ONTO (THERE WERE APPROX 7-8 CONES, AND ONLY THE ONES ON THE EDGE OF THE TXWY HAD DIM FLASHING LIGHTS IN LINE WITH THE OTHER TXWY LIGHTS AND NOT HIGHLY VISIBLE). DUE TO RAIN ON THE WIND SHIELD AND BRIGHTER BACKGROUND LIGHTS, NONE OF THESE MARKINGS WERE SUFFICIENTLY VISIBLE OR ALERTING. UNDER CONDITIONS OF LOW VISIBILITY, WHEN KNOWN OBSTRUCTIONS EXIST ON SURFACE, COPLT'S ATTN IS BETTER DIRECTED OUTSIDE RATHER THAN IMMEDIATELY JUMPING INTO THE AFTER LNDG ITEMS.
