Narrative:
Weather was bad (snow and very low visibility). Taxied air carrier X via delta and delta two and cross runway 23L. I forgot that delta two was closed because it wasn't plowed. Air carrier X slid off the taxiway into the grass at delta two. He didn't know if he was past the hold short lines; so we closed the runway. Had to get a tow to get him off the grass. I just forgot that delta two was closed. It's a common taxiway that we use during the air carrier outbound push and I reverted to old habits.
