It snowed over 6 inches in the hills of Roslindale by 10:00 on Monday morning, and almost that much in Cambridge. The late end to the snow met that the plows were just getting out on the paths as I was headed in. Surprisingly, the DCR takes the prize for timing and thoroughness on the Charles River Bikepath today, at least on the Cambridge side, maybe because I came through soon enough after the plow that there wasn't any drifting near the Weekes Footbridge as there has been in the past. The city of Boston didn't do a uniform job on the Jamaicaway; some parts were great, others had a couple of inches of snow. When they got to it on Tuesday, the Town of Brookline did a spectacular job clearing their path from Route 9 to Chestnut St., but the best plowing I've experienced was on the Neponset Trail in Dorchester and Milton, where there was full-width clear pavement from Shawmut Junction to Central Ave. and a bikeable path on the unpaved stretch from Granite Ave. to Shawmut Junction.

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	The roads are all plowed, mostly to a packed powder surface. There were spots of black ice on the east facing hills. There was still ice on Thursday, but more bare spots and sand along the Bussey Brook side of the road along Hemlock Hill.
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 plowed as of Tuesday night.
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	The shoulders weren't plowed quite to the curb, but there was plenty of room to stay off the main roadway almost to the Forest Hills ramp. The sidewalks were plowed to packed powder over their full width, with mostly bare pavement by Thursday morning.
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	The path was drifted over south of the pond, and the bikepath along the Jamaicaway was not plowed at all from Perkins St. to the path split across from Eliot St. I did some walking. North of Perkins St., the path was plowed before the end of the storm all of the way to Route 9, but it could use more. The path was never re-plowed, and there were still some tricky spots on Thursday morning, though the hill from Perkins St. to Willow Pond Ave. is almost all bare pavement.
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	Both sides are about half their full width, but still usable
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	The paths weren't plowed until Tuesday evening, but the bike path was dry bare pavemnent from Route 9 almost all of the way to Chestnut St. It was packed powder and bikeable the rest of the way to Perkins St.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	The entire path was plowed to packed powder and was pretty easy going. It still hadn't melted much by Thursday morning; there are short stretches of ice where it has melted and refroze.
Commonwealth Ave. Bike Lanes Connecting the B.U. Bridge to Boston University Boston Transportation Department	Fairly clear
Brookline Bike Lanes Town of Brookline	Not checked yet.

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	I've been told that this path is plowed the day after it snows, not right away. I rode it Wednesday night, and the paved stretch from Shawmut Junction (the MBTA overpass) to Central Ave. (and probably Granite Ave. to Pope John Paul II Park) was plowed to dry bare pavement. The unpaved stretch from Granite Ave. to Shawmut Junction along the marsh was plowed to a few inches of packed powder, but there was a path to the bare surface almost all of the way for easier biking.
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, but the main paths are probably plowed

Minuteman "Commuter Bikeway" Towns of Cambridge, Arlington, Lexington, and Bedford	No report yet, but the Arlington section should be plowed. Lexington stopped plowing their part of the path on January 12. Details are posted at http://www.clearthetrail.org
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. I biked them a week ago after snow had melted everywhere else, and there were still a few places where the snow was so deep on the trail that I had to get off and walk my bike. They should have good skiing into the weekend, though.
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.
