A310 FLT CREW MISSED A TURN ISSUED BY ATC WHILE TAXIING IN. THIS RESULTED IN PROCEEDING DOWN A TXWY WHICH APPARENTLY IS WEIGHT RESTRICTED. NEITHER CHARTS NOR NOTAMS INDICATE THIS RESTRICTION.

Narrative

AFTER LANDING ON RWY 8L VANCOUVER WE EXITED AT TXWY M3. WE WERE GIVEN TAXI INSTRUCTIONS INITIALLY AS FOLLOWS; EXIT M3;M;R;K;V... TO PARKING. AFTER READBACK OF THIS CLEARANCE THE TAXI CLEARANCE WAS SUBSEQUENTLY REVISED AS FOLLOWS; M3; M; J; K; V... AS IS NORMAL FOR AFTER LANDING BOTH THE CAPTAIN AND FO ARE BUSY DEALING WITH BOTH THE GROUND MOVEMENT AND AFTER LANDING PROCEDURES. THE CONCLUSION OF THIS FLIGHT COMES AFTER YET ANOTHER THUNDERSTORM EVENT IN ZZZ WHICH DELAYED THE DEPARTURE BY TWO HOURS AND NINE MINUTES. OUR ARRIVAL TIME CORRESPONDED WITH XA54 ACCORDING TO OUR BODY CLOCKS AND WE WERE VERY FATIGUED. THERE IS EXTENSIVE CONSTRUCTION TAKING PLACE ON THE VANCOUVER AIRPORT AND MUCH OF THIS IS DENOTED ON THE GROUND WITH BARRICADES AND LIGHTING. THE REVISED CLEARANCE INCLUDED A RIGHT TURN ON TAXIWAY KILO OFF OF TAXIWAY JULIET. THE CONTINUATION OF TXWY JULIET TO ITS INTERSECTION WITH TXWY HOTEL HAS A GOOD DEAL OF CONSTRUCTION MATERIAL AND GROUND BARRICADES ON BOTH SIDES OF THE TXWY. THERE ARE MEN AND EQUIPMENT ON BOTH SIDES OF THE TXWY PRIOR TO THE INTERSECTION WITH TXWY KILO. BOTH FLIGHT CREWMEMBERS BECAME FOCUSED ON ALL OF THE EQUIPMENT AND BARRICADES THAT WERE ON THE PERIMETER OF TXWY JULIET AND WE MISSED A RIGHT TURN TO TXWY KILO. WE WERE INFORMED OF THIS BY GROUND CONTROL IN WHAT COULD BE DEEMED AS A LESS THAN HOSPITABLE MANNER. HE INFORMED US THAT WE WERE ALSO TAXIING ON A WEIGHT RESTRICTED TXWY. WEIGHT RESTRICTIONS ARE LISTED IN THE CHARTING INFORMATION AND WE CAN FIND NO REFERENCE TO ANY WEIGHT RESTRICTION ON TXWY JULIET. THE NOTAMS FOR VANCOUVER ALSO SHOW CLEARLY THAT NO INFORMATION IS PROVIDED TO THE FLIGHT CREWS REGARDING ANY WEIGHT RESTRICTIONS TO TAXI ON TXWY JULIET. THIS DOES NOT ABSOLVE THE FLIGHT CREW FOR MISSING THE RIGHT TURN AT TXWY KILO; AND FOR THAT I TAKE FULL RESPONSIBILITY. I DO BELIEVE FOR REASONS OF SAFETY CLEARANCES THAT ARE ISSUED TO FLIGHT CREWMEMBERS THAT INVOLVE EIGHT SUCCESSIVE TXWY INSTRUCTIONS SHOULD BE CONSIDERED EXCESSIVE. THE INITIAL TAXI CLEARANCE THAT WOULD HAVE ROUTED THE AIRCRAFT OVER TXWY ROMEO WOULD HAVE PROVIDED THE FLIGHT CREW AN OPPORTUNITY TO FOCUS MORE ON TAXI AND LESS ON CONSTRUCTION EQUIPMENT PROXIMITY TO THE AIRCRAFT. THE TAXI ROUTING CONTINUING ON TXWY J ALSO APPEARS SOMEWHAT OBVIOUS AS A DIRECT ROUTING TO THE INTERSECTION WITH TXWY H. WE BECAME MORE FOCUSED ON THE PERIMETER SAFETY OF THE AIRCRAFT AND MISSED THE RIGHT TURN ON TO TXWY K.
