It started snowing Saturday, turned into a blizzard on Sunday, and kept snowing into Monday, and Boston and environs pretty much shut down with around two more feet of snow on top of the six we already had. Streets have been narrowed and bike lanes have disappeared, sidewalks are barely passable, and bike paths are plowed to sometimes bikable surfaces. In other words, bicycles are definitely the best way to get around!

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 packed powder to ice.
Blackwell Footpath A half-mile gravel path connecting the Forest Hills MBTA station and the South St. Arboretum entrance Boston Parks and Harvard University	Not checked yet, but probably close to impassable on a bike.
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	Mostly gone, but the Cummins Highway lanes have remained partly clear.

Morton St. Buffered Bike Lanes Cemetery Rd. to Harvard St. MassDOT	The bike lanes are buried under three feet of snow, but the buffers are mostly uncovered and usable.
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	Pretty much totally gone under parked cars.
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	Jessica on Monday 2/23: Mixture of bare pavement and ice. It's been plowed several times, but there has been drifting near the boat house and Daisy Field, and I had to get off and walk. Tuesday, it was icy on the hill between Perkin St. and Willow Pond Ave., though I rode it comfortably without studs. Wednesday, I found that the path next to the Pond was clearer and biked to Chestnut St. and followed the Brookline side to Route 9.
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	Under snow or parked cars, except parts of the southbound lane between Chestnut St. and Parkman Drive.
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 but lots of loose snow.
Parkway and Netherlands Rd. Contraflow bike lanes Two one-block contra-flow lanes plus and contraflow cycle track Brookline Park Department and DPW	Still under a pile of snow from the last storm.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Jessica on Monday, 2/23: Solid ice except under the Longwood Ave bridge, this is not recommended without studs or extreme ice biking experience. Earlier: Plowed to packed powder, this was more packed down than the paths in Jamaica Plain.
Commonwealth Ave. Bike Lanes Connecting the B.U. Bridge to Boston University Boston Transportation Department	Pretty much gone.
Brookline Bike Lanes Town of Brookline	Harvard St. lanes are covered by snow or cars except near Brookline Village.
B. U. Bridge Bike Lanes Boston to Cambridge Department of Conservation and Recreation, Plowed By Mass. Highway Department	Totally gone and under lots of snow.
B. U. Bridge west sidewalk Boston to Cambridge Department of Conservation and Recreation, Plowed By Mass. Highway Department or B.U.	Both sidewalks were cleared to bare pavement, but the connections on the Cambridge side aren't very good.
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	The Cambridge approach was very narrow, and I just about had to claim a lane. The main travel lane gets wider on the bridge, and a piece of the bike lane was clear enough to ride in. There was room enough to share with cars on the Boston end. The contraflow lane looked pretty clear.
Charles River Bikepaths Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation	Jonathan Sainsbury reports on Thursday morning: Cleared from Science Park to Mass Ave (probably to BU bridge) Mem Drive is patchy. Mass Ave to Longfellow is ok. Mass Ave to halfway to BU bridge is ok. Not really usable beyond. Jessica on Tuesday: The path upstream from the BU Bridge looked unbikable, but it looked better downstream, toward the BU Boathouse. I haven't dared the Boston side yet. Aaron Pik reported on Monday morning: I decided to give the Charles River path (Cambridge Bank) a go this morning, picking it up at the Hawthorne St. traffic signal. It was briefly rideable. As I got beyond that pack of smaller tress growing right along the water the drifted snow piles grew significantly. I was able to plow through a couple that came about halfway up the seat-tube, but when I got into one up over the top of the wheels I was not able to proceed. I walked a bit, but the drifts were thigh-deep in places. Looking ahead, I could see the whole path was a series of beautiful, wave-like snow drifts. At least to the construction staging area there just before JFK. I crossed Memorial Drive and made my way via JFK park to the roads. JFK park and that little pathway through to the Charles Hotel were nicely cleared.
J.F.K. Park Wide, shared bike-ped path from river to Harvard Square Department of Conservation and Recreation	Plowed to packed powder, with fresh snow on Wednesday.
Western Ave. Cycletrack Cambridge Cambridge DPW	Not checked yet, but it's being used by pedestrians because the city plows it.
Western Ave. Cycletrack Boston Boston DPW	Not checked yet.
N. Harvard St. bike lanes Boston Boston DPW	Pretty much totally under three feet of snow.
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	Plowed to nearly bare pavement.
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Department of Conservation and Recreation	Plowed to packed powder. They were still working on it Tuesday night. I rode it from Forest Hills to Green St. Tuesday morning and from Roxbury Crossing to Jackson Square on Tuesday night. David Wean reported on Tuesday morning: Path was plowed to packed snow. Rideable with skills or studs. Beginning around Heath Street, there were long patches where the City had blown snow banks from Columbus Avenue over into the path, and it was a foot or more deep in dirty snow. DCR staff was working on it (front end loader, one pickup). I bailed at Roxbury Crossing and took Parker Street in.
South Bay Harbor Trail Bike/Ped path from the Federal Court House up Fort Point Channel to the Southwest Corridor City of Boston	Beverley Strain reported on Monday (2/23): South bay Bike Path is clear, but slick from Gillette to Summer St., and there is a path clear at the Children's Museum to the courthouse, but it's very narrow and slick. The connector streets in the area (A St., Melcher, Summer) are cleared, but narrow with on street parking.
Neponset Trail Mostly paved Bike/Ped path Department of Conservation and Recreation	Lee Toma reports: The Neponset trail from Brush Hill Road to Stop and Shop was cleared on Monday, and was rideable, but had some icy patches. The Neponset from Central east was still covered and being used by hikers and snowshoers as of Tuesday night.
Somerville Community Path Wide rail trail from Davis Square to Cedar St. City of Somerville	Not checked, but probably bikeable.
Red Line Linear Park Path Alewife MBTA station to Davis Square over Red Line City of Cambridge City of Somerville	Jonathan Sainsbury reports on Thursday morning: Rough, but walkable and rideable.
Danehy Park Paths City of Cambridge	Jonathan Sainsbury reports on Thursday morning: A little rough, but walkable and rideable.
Cambridge Bike Lanes Striped lanes of varying widths on major and connecting streets City of Cambridge	Sometimes they're slightly usable, like on Brookline St. from the BU Bridge to Central Square, but mostly they're under snow. Some of Mass. Ave. is clear because of selective parking bans.
Vassar St. Cycle Track Buffered bike lanes from Main St. to Memorial Drive (almost) City of Cambridge	Not checked.
Green St./Franklin St. Bicycle Boulevard Narrow one-way streets parallel to Mass. Ave. from Central Square to< Harvard Square/I> City of Cambridge	I've been using Green St. instead of the river paths, and it's been amazingly clear considering that there is nowhere to put the snow. It has been lots worse in past winters.
Fresh Pond Bike Path Parallel to Fresh Pond Parkway in Kingsley Park City of Cambridge	Jonathan Sainsbury reports on Thursday morning: erfect. Good for walking and biking all around the pond. Great for dog walkers.
Alewife Brook Trail DCR	Boardwalk sections aren't plowed. No report on the rest.
Fitchburg Cutoff Trail DCR	Jonathan Sainsbury reports on Thursday morning: Not plowed. Rough pedestrian path. Not rideable.
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	Jonathan Sainsbury reports on Thursday morning: Cleared for challenging walking. Not rideable from Terminal Road to Rotary.
Minuteman "Commuter Bikeway" Towns of Cambridge, Arlington, Lexington, and Bedford	Rod Holland reported on Saturday (2/21): The Minuteman was actually in pretty good shape between Arlington Center and Lexington Center in the early afternoon on Saturday: well plowed, a few very localized problems caused by careless plow or snow-blower operation by people who apparently had other priorities, easy to deal with if you noticed them before hitting them at speed. That's all moot now, with some new snow, perhaps some new ice, a brief thaw, and another freeze coming in rapid succession, but at least it suggests that the next plowing job will proceed from a good baseline. Jonathan Sainsbury reports on Thursday (2/19) morning: Perfect. Good for walking and biking.
Upper Charles Reservation Watertown, Newton, Waltham 4+ miles of paved and unpaved bikepaths Mass. Department of Conservation and Recreation	Not checked yet
Newton Bike Lanes City of Newton	On Thursday, Walnut St. lanes were mostly covered by snow, but when they weren't, it was sure nice to have a bit of extra space to go past long lines of cars.
Revere Beach Reservation Revere Shared use paths (or very wide sidewalks) Mass. 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. Though after this snowfall, the paths should be pretty bikable, and there usually isn't any ice.
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.
