It was just barely starting to snow when I walked home around 9 Sunday night, but by Monday morning, there were 8 inches of very wet snow on the ground. After shovelled my sidewalks, I biked to work on clear streets (with snow shovelled off cars and out of driveways onto them) and fairly clear bike paths. The paths I took were well-plowed, with lots of bare pavement, no ice, and no problems on the occasional unplowed sections with my studded snow tires.

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

Arnold Arboretum 1.5 miles of park roads which are mostly closed to automobile traffic with no intersections Boston Parks and Harvard University	The road between the two Arborway entrances was plowed to bare pavement as was the part of the road up Bussey Hill that I could see
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 Two miles of bike lanes on both sides of Washington St. from Forest Hills to Roslindale Square and to West Roxbury on Belgrade Ave. and buffered and wide bike lanes along American Legion Highway Boston Public Works Department	Still snow-covered on Monday night

Arborway Bike Lanes Bike lanes through Forest Hills Department of Conservation and Recreation	The two-way cycle track which is complete along the Arborway west from South St. was totally clear, but the paths around the station were only occasionally clear in the morning. The southbound cycle track along Washington St. was well-plowed, but the ramp to the Washington St. bike lane was blocked by a pile of snow, which was OK because the bike lane was still covered by snow Monday night.
Arborway sidewalks 1 mile of wide paved shoulder which is unmarked but usually clear of parked cars during rush hour Department of Conservation and Recreation and Boston Parks	Not clear between Arboretum entrances in the morning, but clear to Murray Circle and from Murray Circle all of the way to Jamaica Pond.

Everett Bike Routes Everett Public Works Department	Westbound Sullivan Square cycle track Clear through Everett east of the casino, then unplowed through the rotary, which is probably mostly in Boston. Beacham St to Chelsea The Everett part of this street through the oil tank farm is in as bad shape as I've ever seen it with more potholes than normal(!) and metal sheets and big trucks. For the first time ever, I took a longer route back from Chelse to Sullivan Square (2nd St. to Rt. 99) to avoid it.
