It only snowed a couple of inches on Wednesday morning, January 17, and even less north of the Charles, but it fell wet and was followed by a dusting at night, and then everything remaining froze. Areas that didn't entirely melt during the weekend's rain were camoflaged by the fresh snow, snow froze, too, making simple-looking surfaces potentially dangerous. Thursday's clear skies should let enough sunlight through to melt most of the thin layer of snow on paths, but not in shady areas because the National Weather Service says the temperature will mostly stay around freezing until Saturday and Sunday, when rain is likely to melt everything.

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	Lower road from Forest Hills to Visitor Center was plowed on Wednesday, but might have a thin layer of ice in shaded places, and I would assume those conditions prevale on all of the Arboretum's paved roads.
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	The streets are pretty clear to the curb, so other than watching for ice under the light snow, the lanes on Washington St., Belgrade Ave., and Cummins Highway should be clear.
Centre St. and VFW Parkway Bike Lanes DCR, plowed by MassDOT	Not checked but probably partly clear.
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. is once again unplowed, and there is ice under the snow, so used the sidewalk.
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	Mostly clear after the first snow, with a dusting and some ice by late evening.
Morton St. Buffered Bike Lanes Cemetery Rd. to Harvard St. MassDOT	Not checked

Centre/South Bike Lanes A mile of bike lanes through the heart of Jamaica Plain from Jackson Square and the Southwest Corridor to Forest Hills Boston Public Works Department	Clear because cars can now park to the curb. Parking lanes are narrow, though, so delivery trucks and large SUV's stick into the bike lane sometimes.
Jamaicaway Bikepath 1.5 miles of mostly bike/ped-separated paths paralleling a busy 4-lane parkway; two intersections with traffic lights Boston Parks Deparment	Plowed by midday Wednesday, but not always to bare pavement. Later snow covered it all, but only lightly. Thawed snow froze in shade, so there is occasionally ice, but it can usually be avoided.
Prince St. A future contraflow lane around high-speed Parkman Drive which feeds into the Perkin St. bike lanes Boston DPW	Clear.
Perkins St. Bike Lanes 1.5 miles of mostly bike/ped-separated paths paralleling a busy 4-lane parkway; two intersections with traffic lights Department of Conservation and Recreation	Old snow melted off, and road salt melted Wednesdays fresh snow, so these were almost totally clear on Wednesday night.
Olmsted Park Paths 3/4-mile of mostly bike/ped-separated paths built over Riverdale Road, across Leverett Pond from the Jamaicaway. Brookline Park Department	Mostly clear on Wednesday midday. With a dusting on top that night after the freeze, watch for ice.

Fell and broke my clavicle. In the Cambridge Hospital ED. I don't think I was even braking, not going fast. Of course, they came to treat the path, as the ambulance arrived, presumably because they learned about the 911 call. It didn't even seem like the roads had been treated. Was DPW just hoping the ice would eventually melt?
Mass. Ave. Cycle Track Parking-buffered bike lanes outbound before and after Harvard Square City of Cambridge	Not checked yet, but watch for black ice.
Green St./Franklin St. Bicycle Boulevard Narrow one-way streets parallel to Mass. Ave. from Central Square to Harvard Square/I> City of Cambridge	Probably clear, but shaded, so watch for ice.

Both plowed down to asphalt, but both have thin sheets of ice for long sections. Studded tires necessary today, but most of this will melt very quickly when we get above freezing.
Wellington Greenway Malden Shared use path Malden DPW	Jon Ramos reports that the section which goes under the Orange Line tracks and up the Malden River, "it was choppy ice.... a challenge even with the studs."
Stony Brook Reservation Hyde Park 4+ miles of paved bikepaths Mass. Department of Conservation and Recreation	These paths aren't plowed because they get relatively little transportation use and because they are used by cross-country skiers like me.
