It started snowing Thursday morning and and alternated between rain and snow into the night, with the temperature hovering around freezing. We got a bit more snow in Boston than was forecast, maybe as much as 6 inches. There is ice everywhere, both on paths and on the edges of roads, definitely a day when studded tires inspire more confidence. Neoprene Bike Mitts kept my hands pretty dry, too. Since I biked to and from work on different routes, I got to see a variety of conditions, most of which I would not term bike-friendly.

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	Not checked yet, but probably icy because they don't salt.
Blackwell Footpath A half-mile gravel path connecting the Forest Hills MBTA station and the South St. Arboretum entrance Boston Parks and Harvard University	I didn't check it, but it is certainly not plowed and 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. Boston Public Works Department	Clear, but often blocked by parked cars, and the paint is really wearing away.
Arborway "Bike Lanes" 1 mile of wide paved shoulder which is unmarked but usually clear of parked cars during rush hour Department of Conservation and Recreation,	Narrowed
Morton St. Buffered Bike Lanes Cemetery Rd. to Harvard St. MassDOT	Buffer and 1/2 to 3/4 of lane clear to bare pavement by Saturday morning.
Franklin Park Roads Much of the park loop road is closed to motorized traffic and there are bike lanes on the main road. Boston Parks and Public Works Departments	Not checked yet.
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	Like Roslindale, the bike lanes were clear, but cars were parked on them due to snow piled at the curb.
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	By Thursday night, there was quite a bit of bare pavement with slush. There was ice at the bottom of the hill south of Willow Pond Ave., so I would recommend studded tires even here.
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	Narrowed to near extinction
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	Plowed to ice by Thursday night.
Parkway and Netherlands Rd. Contraflow bike lanes Two one-block contra-flow lanes plus and contraflow cycle track Brookline Park Department and DPW	Parkway contraflow lane is mostly clear to pavement. Netherlands Rd. contra-flow lane still not plowed. Contraflow cycle track plowed but only narrow clear path.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Packed snow to ice with a few clear stretches. I encountered two trucks plowing on Friday morning, but they didn't quite get to bare pavement.
Commonwealth Ave. Bike Lanes Connecting the B.U. Bridge to Boston University Boston Transportation Department	Very clear by Thursday morning, at least where there were no parked cars.
Brookline Bike Lanes Town of Brookline	Harvard St. bike lanes were plowed, but cars parked into them all too often.
B. U. Bridge Bike Lanes Boston to Cambridge Department of Conservation and Recreation, Plowed By Mass. Highway Department	Clear on Thursday morning.
B. U. Bridge west sidewalk Boston to Cambridge Department of Conservation and Recreation, Plowed By Mass. Highway Department or B.U.	It looked icy Thursday morning but not checked after storm.
Harvard (Mass. Ave.) Bridge bike lanes Cambridge to Boston Department of Conservation and Recreation, Plowed By Mass. Highway Department	Not checked yet.
Longfellow Bridge bike lanes Cambridge to Boston Department of Conservation and Recreation, Plowed By Mass. Highway Department	Pretty clear except Boston end by Friday night.
Boston Common Paths Boston Boston Parks Department	Despite the fact that bikes aren't allowed, these well-plowed paths, especially the wide ones allow access from Charles St., which is more bike-friendly than Cambridge St., coming off the Longfellow Bridge to Downtown Crossing. By Friday night, they were all clear, and I used the side one parallel to Charles St. as a contraflow lane to get to Boylston and a play at the Paramount Theater.
Charles River Bikepaths Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation	Expecting them to be icy from the remnants of the last storm and late plowing, I have been avoiding them.
J.F.K. Park Wide, shared bike-ped path from river to Harvard Square Department of Conservation and Recreation	Plowed to slush on Thursday night.
Western Ave. Cycletrack Cambridge Cambridge DPW	Not checked yet.
Western Ave. Cycletrack Boston Boston DPW	Not checked yet.
N. Harvard St. bike lanes Boston Boston DPW	Narrowed by snow and large puddles.
Lincoln St. to Cambridge St. MassPike Bridge Bike/Ped connection from Harvard Square to Allston's Harvard Ave. district via Franklin St. Massachusetts Turnpike Authority	North approach was plowed, but very icy, but the bridge was clear. South approach was unplowed and difficult. Safer on studded tires than on foot!
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Department of Conservation and Recreation	From Roxbury Crossing to Forest Hills, the path was well-plowed, but poor drainage of melting snow led to unavoidable stretches of black ice by Friday night. It was an easy and fast ride on studded tires, but I would avoid it without studs.
South Bay Harbor Trail Bike/Ped path from the Federal Court House up Fort Point Channel to the Southwest Corridor City of Boston	Not checked.
Neponset Trail Mostly paved Bike/Ped path Department of Conservation and Recreation	Not checked yet
Somerville Community Path Wide rail trail from Davis Square to Cedar St. City of Somerville	Not checked, but probably plowed.

Danehy Park Paths City of Cambridge	Not checked, but probably plowed
Cambridge Bike Lanes Striped lanes of varying widths on major and connecting streets City of Cambridge	Not always plowed, and often parked over. The Hampshire St. lanes were often usable by Friday night.
Vassar St. Cycle Track Buffered bike lanes from Main St. to Memorial Drive (almost) City of Cambridge	Not checked.
Fresh Pond Bike Path Parallel to Fresh Pond Parkway in Kingsley Park City of Cambridge	Not checked yet
Alewife Brook Trail DCR	Stone dust and boardwalk sections are never plowed. You could probably ride it with snow tires because pedestrians pack it down.
Fitchburg Cutoff Trail DCR	Not checked yet.
Concord Ave. Cycle Track Buffered bike lanes from Belmont to Fresh Pond Parkway City of Cambridge	Not checked yet.
Alewife Parkway Bridge Sidewalk Connection from Minuteman Bikepath to Fresh Pond and beyond Department of Conservation and Recreation	Not checked yet.

Northern Strand Community Trail Everett and Malden Shared use path Everett and Malden DPW	No Report.
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. There are marked narrow bike lanes on Enneking Parkway through the reservation which are probably clear.
Former Metropolitan State Hospital Belmont, Waltham paved bikepaths Mass. Department of Conservation and Recreation	Not checked yet.
Assabet River Rail Trail Hudson and Marlborough, so far Town of Hudson, City of Marlborough (so far)	Not checked, but probably not plowed.
Northampton Bikeway East-west across the City of Northampton City of Northampton	Craig Della Penna, who lives next to the path, has reported that it is the intention of the DPW to make it passable ASAP after a storm. If the storm is significant, then they plow it repeatedly --sometimes 10-12 times during the course of the storm to ensure its usability.
Norwottuck Rail Trail Northampton to Amherst Department of Conservation and Recreation	No report.
