It started snowing late Wednesday night and continued until Thursday afternoon dropping a foot of snow on Boston. I shoveled and worked on Thursday, then woke early and biked downtown to a doctor's appointment on Friday morning. I left early enough that I could stop and take photos on my way in and took more on an entirely different route home. I was able to use bike facilities starting a mile from home on my way in and ending less than a half-mile from home on my way back, taking a photo of almost every bike lane, path, or cycle track which I used. Almost everything was plowed, but not so well that my hybrid with studded tires wasn't useful.

Here are photos of most of the facilities I used.

The order looks random, but paths and lanes are listed in the order in which I used to encounter them on my morning commute, then they tend to go radially outward from the area where I most commonly travel.

Please send updates and reports on the conditions of other paths in Massachusetts to Jessica Mink.

Forest Hills Station Cycle tracks along South and Washington Streets and the Arborway MBTA and DCR	The bicycle paths were plowed as well as the sidewalks, not perfect, but cyclable in the morning. There was no access to the bicycle rotary from the east and the ramp between the end of the cycle track and the southbound bike lanes on Washinton St. was not plowed.
Arnold Arboretum 1.5 miles of park roads which are mostly closed to automobile traffic with no intersections Boston Parks and Harvard University	On Friday morning, the road between the two Arborway entrances was lightly-sanded packed snow, and I was glad I had my studded snow tires.
Blackwell Footpath A half-mile gravel path connecting the Forest Hills MBTA station and the South St. Arboretum entrance Boston Parks and Harvard University	It didn't look plowed when I biked by on Washington St. and can be pretty icy.
Roslindale Bike Lanes on Washington St, Belgrade Ave., Cummins Highway, American Legion Parkway Boston Public Works Department	Washington St. bike lanes Half-blocked by parked cars most of the way.

Prince St. A future contraflow lane around high-speed Parkman Drive which feeds into the Perkin St. bike lanes Boston DPW	The street is probably clear, but I avoid it when the temperature is below freezing because I have a hard time on the patch of slick ice which often stretches all of the way across the road at the intersection with Perkins St.
