Narrative:

Lgb airport had construction on numerous txwys in progress. The normal taxi route to our departure runway (runway 30) was not useable. I was familiar with the airport and aware that numerous runways and txwys were restr for operation by our aircraft type (B727). After pushback and start, the first officer called lgb ground for taxi. The ground controller gave us instructions to taxi to and hold short of runway 25L, use taxiway D, and hold short of runway 34R. We, the crew, thought these instructions were incorrect, so, I called ground control to verify our taxi instructions. At the end of my transmission, we could hear the last part of lgb ground's new taxi instructions. I then tried to explain that we blocked their transmission and to 'say again.' lgb ground got upset with us and said just taxi straight ahead, and that lgb ground would guide us for our taxi (give us progressive taxi instructions). Lgb ground also included that we were to taxi via taxiway F, left on taxiway D, right on runway 25L to cross runway 30, and right on taxiway left to runway 30. In the meantime we were trying to figure out the taxi route (the taxi was different from 2 days before). Lgb ground called us again and urged us to start our taxi so they could direct us. I failed to remember runway 25L had a maximum wingspan limit of 90 ft. We taxied at the insistence of lgb ground. In my haste I complied with lgb ground control's insistence. Unfortunately, we complied with lgb ground's clearance and taxied briefly on runway 25L from taxiway D to taxiway left. I had an uneasy feeling about the whole event. After departure, I found the note on a company page that runway 25L was restr to aircraft with wingspans 90 ft of less. Our aircraft's wingspan is 108 ft! I confused the runway restrs for runway 25R and runway 25L. How to prevent this situation in the future. 1) if in doubt, always stop and find out for sure, 2) never let ATC push you into doing something before you are already, 3) always know ahead what taxi routes you can and cannot take, and 4) do not be complacent. If something is different, ask why!

Title: B727 FLC INDECISION, LGB ARPT CONSTRUCTION AND GND CTLR BADGERING CAUSE TAXI ONTO A WING SPAN RESTR AREA.

Narrative: LGB ARPT HAD CONSTRUCTION ON NUMEROUS TXWYS IN PROGRESS. THE NORMAL TAXI RTE TO OUR DEP RWY (RWY 30) WAS NOT USEABLE. I WAS FAMILIAR WITH THE ARPT AND AWARE THAT NUMEROUS RWYS AND TXWYS WERE RESTR FOR OP BY OUR ACFT TYPE (B727). AFTER PUSHBACK AND START, THE FO CALLED LGB GND FOR TAXI. THE GND CTLR GAVE US INSTRUCTIONS TO TAXI TO AND HOLD SHORT OF RWY 25L, USE TXWY D, AND HOLD SHORT OF RWY 34R. WE, THE CREW, THOUGHT THESE INSTRUCTIONS WERE INCORRECT, SO, I CALLED GND CTL TO VERIFY OUR TAXI INSTRUCTIONS. AT THE END OF MY XMISSION, WE COULD HEAR THE LAST PART OF LGB GND'S NEW TAXI INSTRUCTIONS. I THEN TRIED TO EXPLAIN THAT WE BLOCKED THEIR XMISSION AND TO 'SAY AGAIN.' LGB GND GOT UPSET WITH US AND SAID JUST TAXI STRAIGHT AHEAD, AND THAT LGB GND WOULD GUIDE US FOR OUR TAXI (GIVE US PROGRESSIVE TAXI INSTRUCTIONS). LGB GND ALSO INCLUDED THAT WE WERE TO TAXI VIA TXWY F, L ON TXWY D, R ON RWY 25L TO CROSS RWY 30, AND R ON TXWY L TO RWY 30. IN THE MEANTIME WE WERE TRYING TO FIGURE OUT THE TAXI RTE (THE TAXI WAS DIFFERENT FROM 2 DAYS BEFORE). LGB GND CALLED US AGAIN AND URGED US TO START OUR TAXI SO THEY COULD DIRECT US. I FAILED TO REMEMBER RWY 25L HAD A MAX WINGSPAN LIMIT OF 90 FT. WE TAXIED AT THE INSISTENCE OF LGB GND. IN MY HASTE I COMPLIED WITH LGB GND CTL'S INSISTENCE. UNFORTUNATELY, WE COMPLIED WITH LGB GND'S CLRNC AND TAXIED BRIEFLY ON RWY 25L FROM TXWY D TO TXWY L. I HAD AN UNEASY FEELING ABOUT THE WHOLE EVENT. AFTER DEP, I FOUND THE NOTE ON A COMPANY PAGE THAT RWY 25L WAS RESTR TO ACFT WITH WINGSPANS 90 FT OF LESS. OUR ACFT'S WINGSPAN IS 108 FT! I CONFUSED THE RWY RESTRS FOR RWY 25R AND RWY 25L. HOW TO PREVENT THIS SIT IN THE FUTURE. 1) IF IN DOUBT, ALWAYS STOP AND FIND OUT FOR SURE, 2) NEVER LET ATC PUSH YOU INTO DOING SOMETHING BEFORE YOU ARE ALREADY, 3) ALWAYS KNOW AHEAD WHAT TAXI ROUTES YOU CAN AND CANNOT TAKE, AND 4) DO NOT BE COMPLACENT. IF SOMETHING IS DIFFERENT, ASK WHY!
