ExXB:
"A Swiss International Air Lines Boeing 777 300 (HB-JND/ SWR40) from Zurich, Switzerland (LSZH) to Los Angeles, CA (KLAX) (diverted to Iqaluit, NU, see # 2017C0405) got stuck in the turn around bay at the Threshold of 16. The runway was NOTAMed closed until the aircraft was towed clear at 2110Z."

If that chart is well-drawn and still current, the turn-round bay near the end of Rwy 34 would present quite a challenge for a long-wheelbase twin taxying on one engine, particularly in wintry conditioons.
