You may want to have a back up route in mind that goes where the plow and salt. Try to avoid sidewalks and bicycle paths because they are untreated and sometimes can be very rough especially if it freezes.
Case in point, last week it snowed, melted a little and then froze. My regular route includes to small bike paths. They froze hard and I slid and took a bad fall. It hurt a lot. Avoid this if you can!
During the work day I found another route that I could take that did not include the bike paths. It was much safer.
