It snowed another 4-6 inches starting Wednesday morning, then turned to rain during the afternoon, creating a real mess. The Charles RIver Path was hard to ride in the morning, but flooded in the evening. Leverett Pond seemed to come up through the snow to the Jamaicaway Path, covering it with several inches of water, but I made it home. And then everything froze, so Thursday morning was really slippery.

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 in the morning. Along Bussey Brook, the road stayed icy all week, though the Arboretum put down sand along the edge after a couple of days because people couldn't even walk there. Studded bike tires were required! The hills melted off after a day, though.
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.
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	A bit over half the width was plowed, enough to mostly stay off the main travel lanes almost to the Forest Hills entrance from the crosswalk.
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 flat part along Jamaica Pond was solid rough ice on Thursday, but it was broken up quite a bit by Friday. The hill between Perkins St. and Willow Pond was salted and felt pretty safe. From Willow Pond to Route 9, the path was slippery Thursday, but fairly clear by Friday.
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	The eastbound bike lanes are almost entirely snowed in. The westbound ones are a bit clearer
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, but they looked icy.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	Icy for a few days, but gradually clearer. The path was salted only around the Longwood Green Line stop.
Commonwealth Ave. Bike Lanes Connecting the B.U. Bridge to Boston University Boston Transportation Department	Fairly clear
Brookline Bike Lanes Town of Brookline	Covered with snow or parked cars pushed out from the curb by snow

Charles River Bikepath Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation, Division of Urban Parks and Recreation	Wednesday morning, I made my way up the river from the B.U. Bridge to Harvard Square, but it was hard. Wednesday night, the trail had a couple of inches of water on top of the ice and was worse. I left it alone for the rest of the week.
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 Friday.
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	Slushy Wednesday night, but totally clear by the following Monday.

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 not always right away. 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.

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	Wherever there are parked cars, they seem to be far enough out into the street that most of the lanes are gone. Where there aren't any parked cars, the path was often covered with piles of snow, because there wasn't anywhere else to put it.
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.

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. See my photos of the path on Monday at http://www.masspaths.net/stonybrook/
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.
