Yes, they do. But it's a single lane, and they can only push the snow to the end of the pier. What can happen (if it snow while you are away) is a ridge of snow is formed on either side of the plow path. When the snow freezes and thaws it can create a hard frozen ridge you need to either clear (with a shovel with a metal edge) or back over it (and hope you have clearance). Port staff sands / salts the spiral road way up to the parking deck. I could have made a lot of money shoveling folks out years ago... but wanted to get home. By the way, for fourteen cruises in February from NYC this has only happened to us once.
