Narrative:

After a 3.5 hour situation that turned into over 7 hours, due to late inbound equipment, we received a clearance to las with no mention of the tower closing in 20 mins. When calling for push, we determined tower was closed, even though we received permission to depart during curfew. During taxi on taxiway Y, we were reviewing part 1 on tower closed operations, changing takeoff numbers due to decrease in load and a slight tailwind on runway 30L, and trying to contact oak for IFR release into their airspace. Close to taxiway C, we noticed construction in progress on approach end of runway 30R. Trying to avoid a possible taxiway conflict, we elected to cross runway 30L and taxi down west side of airport not noticing wingtip restr on taxiway west. After crossing on runway C, but before turning on taxiway west, we determined taxiway west was too narrow. After determining wingtip clearance and no mention of weight restr, we did an idle power 180 degree turn on taxiway C, back taxied on runway 30L and took off. We felt pressure because the next day's flight, las to dfw, was already delayed due to crew rest and we wanted to minimize delay as much as possible.

Title: A B757-200 CAPT RPTED THAT, DURING TAXI AFTER SJC TWR HAD CLOSED, HE INCURRED ON TXWY C WHICH WAS TOO NARROW.

Narrative: AFTER A 3.5 HR SIT THAT TURNED INTO OVER 7 HRS, DUE TO LATE INBOUND EQUIP, WE RECEIVED A CLRNC TO LAS WITH NO MENTION OF THE TWR CLOSING IN 20 MINS. WHEN CALLING FOR PUSH, WE DETERMINED TWR WAS CLOSED, EVEN THOUGH WE RECEIVED PERMISSION TO DEPART DURING CURFEW. DURING TAXI ON TXWY Y, WE WERE REVIEWING PART 1 ON TWR CLOSED OPS, CHANGING TKOF NUMBERS DUE TO DECREASE IN LOAD AND A SLIGHT TAILWIND ON RWY 30L, AND TRYING TO CONTACT OAK FOR IFR RELEASE INTO THEIR AIRSPACE. CLOSE TO TXWY C, WE NOTICED CONSTRUCTION IN PROGRESS ON APCH END OF RWY 30R. TRYING TO AVOID A POSSIBLE TXWY CONFLICT, WE ELECTED TO CROSS RWY 30L AND TAXI DOWN W SIDE OF ARPT NOT NOTICING WINGTIP RESTR ON TXWY W. AFTER XING ON RWY C, BUT BEFORE TURNING ON TXWY W, WE DETERMINED TXWY W WAS TOO NARROW. AFTER DETERMINING WINGTIP CLRNC AND NO MENTION OF WT RESTR, WE DID AN IDLE PWR 180 DEG TURN ON TXWY C, BACK TAXIED ON RWY 30L AND TOOK OFF. WE FELT PRESSURE BECAUSE THE NEXT DAY'S FLT, LAS TO DFW, WAS ALREADY DELAYED DUE TO CREW REST AND WE WANTED TO MINIMIZE DELAY AS MUCH AS POSSIBLE.
