This [report] is regarding the incident where I and my partner taxied Aircraft X from gate to Company hangar. We were given the route to hangar from ATC Ground 'ALPHA; ALPHA 7; TANGO; WEST GATE; YANKEE; YANKEE TO HANGAR'. When we approached [the] west gate; we noticed on the right side of Taxiway Yankee; beside [another] hangar; before making a right turn to the a hangar; a huge bank of snow aligned with the number 2 engine. The snow bank was about 25 [feet] left [of] the taxi blue lights and about 50 [feet] long. I screamed to my taxi partner to veer to the left to clear the number 2 engine. Once arriving [to hangar]; [we] performed out post-taxi walk-around and inspected number 2 engine for possible impact damage. We inspected and found no damage.Event occurred because [the] city's cleaning operations didn't plow snow off Taxiway Yankee towards blue taxi lights.
Reporter stated that during taxi of aircraft from gate to hanger; aircraft almost made contact with snow bank that had not been plowed off taxiway by airport personnel.
