Narrative:

While crossing runway 4; we were given a left turn onto taxiway bb; hold short of taxiway Y. I glanced at taxiway bb from the airport diagram and noted no restrs. My focus of attention was redirected back to visual taxi lookout. When stopped and holding short of taxiway Y; as directed by ground control; we noticed that while there is no restr for B757's on taxiway bb; there is a restr from turning either direction off of taxiway bb. In other words; it is a dead-end for B757's. The captain called the chief pilot on duty and discussed the situation. We were informed that if we could safely taxi with wing walkers we could proceed from taxiway bb; left on taxiway Y then left on taxiway aa. This we did with port authority/authorized wing walkers and at no time was there a question of adequate wing clearance. The chief pilot on call was a tremendous help. I recommend a note be added on the airport page restricting B757's from even turning onto taxiway bb; left from taxiway D. Lga taxiing is very tight; quick and dynamic and requires outside safety lookout at all times.

Title: B757-200 CREW WAS DIRECTED L FROM TXWY D ONTO AN LGA TXWY BB WHERE ALL EXIT ACCESS TXWYS HAVE WINGSPAN CONSTRAINTS RESTRICTING LARGE ACFT MOVEMENTS.

Narrative: WHILE XING RWY 4; WE WERE GIVEN A L TURN ONTO TXWY BB; HOLD SHORT OF TXWY Y. I GLANCED AT TXWY BB FROM THE ARPT DIAGRAM AND NOTED NO RESTRS. MY FOCUS OF ATTN WAS REDIRECTED BACK TO VISUAL TAXI LOOKOUT. WHEN STOPPED AND HOLDING SHORT OF TXWY Y; AS DIRECTED BY GND CTL; WE NOTICED THAT WHILE THERE IS NO RESTR FOR B757'S ON TXWY BB; THERE IS A RESTR FROM TURNING EITHER DIRECTION OFF OF TXWY BB. IN OTHER WORDS; IT IS A DEAD-END FOR B757'S. THE CAPT CALLED THE CHIEF PLT ON DUTY AND DISCUSSED THE SIT. WE WERE INFORMED THAT IF WE COULD SAFELY TAXI WITH WING WALKERS WE COULD PROCEED FROM TXWY BB; L ON TXWY Y THEN L ON TXWY AA. THIS WE DID WITH PORT AUTH WING WALKERS AND AT NO TIME WAS THERE A QUESTION OF ADEQUATE WING CLRNC. THE CHIEF PLT ON CALL WAS A TREMENDOUS HELP. I RECOMMEND A NOTE BE ADDED ON THE ARPT PAGE RESTRICTING B757'S FROM EVEN TURNING ONTO TXWY BB; L FROM TXWY D. LGA TAXIING IS VERY TIGHT; QUICK AND DYNAMIC AND REQUIRES OUTSIDE SAFETY LOOKOUT AT ALL TIMES.
