It snowed a couple of inches last night, so light and fluffy that I could shovel my walk in a few minutes. It covered all the dirty snow with bright white and drifted a bit on some bike paths, but mostly conditions remained the same as yesterday, so I'm taking advantage of this for a complete update 10 days after the last major snowstorm. Everything is either icy or clear. If you don't have studded tires or good ice biking skills, stay off the paths and learn to communicate with other street users so you can share streets narrowed by high piles of snow.

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 from the Visitors Center entrance to the Forest Hills entrance is relatively smooth packed powder, not very icy at all. I rode it pretty fast on studded tires. It looks pretty skiable, too.
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.
Centre St. and VFW Parkway Bike Lanes DCR, plowed by MassDOT	Not checked, but probably snow-covered.
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	Kelly to Murray Circle: Mostly covered by snow near the rotaries, but ridable in between. Murray Circle to Forest Hills: mostly clear and quite usable.
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; clearer when there is no parking.
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	Between Kelly Circle and Perkin St., there's a lot of drifted snow on very rough ice. From Perkin St. to Rt. 9, there is a lot of ice, and I wouldn't bike it without studded tires.
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, except parts of the southbound lane between Chestnut St. and Prince St., which I have been using instead of the Jamaicaway Path.
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 pretty much all rough ice. I rode it once, but no more.
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.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Pretty much solid rough ice, and I'm now using streets instead.

Brookline Bike Lanes Town of Brookline	Harvard St. lanes are mostly clear.
B. U. Bridge Bike Lanes Boston to Cambridge Department of Conservation and Recreation, Plowed By Mass. Highway Department	Starting to return.

Harvard (Mass. Ave.) Bridge bike lanes Cambridge to Boston Department of Conservation and Recreation, Plowed By Mass. Highway Department	Nick Carlisle reports on Thursday, February 26: Cambridge-bound bike lanes are moderately plowed, definitely usable in some spots but not as a whole. Advise taking the right lane. Boston-bound bike lanes are non-existent as of this morning.
Longfellow Bridge bike lanes Cambridge to Boston Department of Conservation and Recreation, Plowed By Mass. Highway Department	Not checked recently, but maybe starting to get clear.
Charles River Bikepaths Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation	On the Boston side, it's clear to bare pavement along the Esplanade, but pretty narrow and snowy upstream from the BU Bridge to River St. I had to get off and walk a few times. The Dartmouth St. footbridge was bare pavement. On the Cambridge side, it's rough ice from the BU Bridge to Western Ave., then pretty clear to the Weekes Footbridge, then rough ice upstream to Hawthorn St.
J.F.K. Park Wide, shared bike-ped path from river to Harvard Square Department of Conservation and Recreation	Plowed to rough ice with occasional pavement, about the worse I've ever seen it this long after a storm.
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 bare pavement.
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Department of Conservation and Recreation	Mostly bare pavement between Ruggles and Jackson Square, but not consistently clear south from there. I wouldn't ride from Forest Hills without studded tires.
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.

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	Nick Carlisle reports on Thursday, February 26: plowed and clean, but advise riders to be especially careful in both directions where the lane "spits" you out back into the road, both because a) on-street lanes are not plowed and b) snowbanks obstruct drivers' view of incoming cyclists.
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.
