Narrative:
There were at least 3 inches of snow/ice on the ground and it was snowing/freezing rain. At the time we were deiced, we were in line to deice from XA30 to XB55 -- a long time for anyone to wait. After deicing was completed, we taxied to runway 9L for takeoff. The captain was taxiing the aircraft slowly because of the very slick and icing conditions. As I looked up we were approaching taxiway left which has no access to runway 9L. By the time we realized there was no access, we were at the mouth of taxiway Y and we stopped and talked to tower who said we could turn around and taxi to runway 9L for position and hold. The captain had to use at least 50% reverse thrust to avoid slipping off the taxiway during the u-turn. He did not use reverse thrust to back up, only to stop our forward slide while we were turning. Once the turn was completed, we taxied to runway 9L and departed.

Title: A COMMERCIAL FIXED WING ACFT TAXIING ON AN ICE COVERED TXWY MISSED THE RWY TURNOFF, MADE A U-TURN NARROWLY MISSING A TXWY EXCURSION.
Narrative: THERE WERE AT LEAST 3 INCHES OF SNOW/ICE ON THE GND AND IT WAS SNOWING/FREEZING RAIN. AT THE TIME WE WERE DEICED, WE WERE IN LINE TO DEICE FROM XA30 TO XB55 -- A LONG TIME FOR ANYONE TO WAIT. AFTER DEICING WAS COMPLETED, WE TAXIED TO RWY 9L FOR TKOF. THE CAPT WAS TAXIING THE ACFT SLOWLY BECAUSE OF THE VERY SLICK AND ICING CONDITIONS. AS I LOOKED UP WE WERE APCHING TXWY L WHICH HAS NO ACCESS TO RWY 9L. BY THE TIME WE REALIZED THERE WAS NO ACCESS, WE WERE AT THE MOUTH OF TXWY Y AND WE STOPPED AND TALKED TO TWR WHO SAID WE COULD TURN AROUND AND TAXI TO RWY 9L FOR POS AND HOLD. THE CAPT HAD TO USE AT LEAST 50% REVERSE THRUST TO AVOID SLIPPING OFF THE TXWY DURING THE U-TURN. HE DID NOT USE REVERSE THRUST TO BACK UP, ONLY TO STOP OUR FORWARD SLIDE WHILE WE WERE TURNING. ONCE THE TURN WAS COMPLETED, WE TAXIED TO RWY 9L AND DEPARTED.
