An overnight snowfall turned to rain, which wasn't freezing, at least in the city. I biked to work, but not entirely on paths as I had several errands to run on the way. Boston plowed the Jamaicaway (and probably the Arboretum) and Brookline seems to have at some point plowed the Muddy River Path, but the Charles River path in Cambridge was untouched by noon.

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

Arnold Arboretum 1.5 miles of park roads which are mostly closed to automobile traffic with no intersections Boston Parks and Harvard University	I rode the lower road from the main entrance to the Forest Hills entrance on my way home in the evening, and there was continuous bare pavement except around the entrances. Thursday morning, I rode through the Arboretum from Alter St. to the Arborway, and it was icy almost all of the way. Some will melt in the sun, but the road along Hemlock Hill will probably be icy for quite a while.
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, Division of Urban Parks and Recreation	At least half clear by evening.
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 and sanded to bare pavement by evening, though it was passable in the morning. It was a bit icy after the overnight freeze, but ridable on Thursday morning.
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 Division of Urban Parks and Recreation	These lanes were not very clear this morning, but the sidewalk on the north side of Perkin St. was well-plowed.
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	Not checked.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Plowed early and passable in the morning, but clearer by evening.
Commonwealth Ave. Bike Lanes Connecting the B.U. Bridge to Boston University Boston Transportation Department	I only rode a short stretch between Carleton St. and the B.U. Bridge, but the bike lane was totally clear and seemed to be just as good eastward.
B.U. Bridge Easy connection to Charles River bikepath Department of Conservation and Recreation, Division of Urban Parks and Recreation	The west sidewalk is closed due to construction, so I usually ride the road these days, but the east sidewalk is plowed.
Charles River Bikepath Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation, Division of Urban Parks and Recreation	By evening commute, the Cambridge side was plowed from the B.U. Bridge upstream past Hawthorn St. (and probably to the Eliot Bridge), though in the morning, it had been so covered with deep, icy slush that I bailed to the streets immediately. On Thursday morning, it was pretty icy, but will probably clear up a bit in the sun. It definitely helped to have studded snow tires.
J.F.K. Park Wide, shared bike-ped path from river to Harvard Square Department of Conservation and Recreation, Division of Urban Parks and Recreation	Clear by Thursday morning.
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	I haven't checked this yet, but MassPike usually does a pretty good job of keeping clear.
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Department of Conservation and Recreation, Division of Urban Parks and Recreation	Not checked yet.
Melnea Cass Bikepath Separated Bike/Ped path Boston Parks or Transportation Deparment	Not checked yet, but probably not plowed.
Harborwalk (Fort Point Channel) Bike/Ped path along Fort Point Channel Department of Conservation and Recreation, City of Boston	Not checked yet.
Neponset Trail Mostly paved Bike/Ped path Department of Conservation and Recreation, Division of Urban Parks and Recreation	The DCR often plows this path, but it hasn't been plowed since the last storm. If you use this path regularly and want the DCR to plow it, let them know (or thank them when it is plowed) at 617-626-4973 or contact DCR Community Affairs. http://www.mass.gov/dcr/aboutDCR.htm.
Somerville Community Path Wide rail trail from Davis Square to Cedar St. City of Somerville	Not checked, but probably plowed.
Red Line Linear Park Path Alewife MBTA station to Davis Square over Red Line City of Cambridge City of Somerville	Not checked but probably plowed.
Danehy Park Paths City of Cambridge	Not checked yet.
Cambridge Bike Lanes Striped lanes of varying widths on major and connecting streets City of Cambridge	The Mass. Ave. lanes around Harvard Square were OK, but lanes on side streets, such as the Waterhouse St. and little Concord Ave. contraflow lanes, were deep slush.
Fresh Pond Bike Path Parallel to Fresh Pond Parkway in Kingsley Park City of Cambridge	No report yet
Alewife Parkway Bridge Sidewalk Connection from Minuteman Bikepath to Fresh Pond and beyond Department of Conservation and Recreation, Division of Urban Parks and Recreation	No report yet.
Minuteman "Commuter Bikeway" Towns of Cambridge, Arlington, Lexington, and Bedford	No report yet. Details might be posted at http://www.clearthetrail.org/news.htm
Upper Charles Reservation Watertown, Newton, Waltham 4+ miles of paved and unpaved bikepaths Mass. Department of Conservation and Recreation Division of Urban Parks and Recreation	These paths aren't plowed.
Stony Brook Reservation Hyde Park 4+ miles of paved bikepaths Mass. Department of Conservation and Recreation Division of Urban Parks 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.
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, reports 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, Division of State Parks and Recreation	No report yet.
