By 9:00 am this morning, there were at least six inches of snow on my sidewalks. The lowest level was pretty wet, but it got drier toward the top and the snow which was still falling, until noon or so, was light enough to start drifting. It looked like there was less snow by the Charles River and in Cambridge; maybe it started as rain there.

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 park roads were plowed pretty well. They might freeze up by tomorrow morning since it is supposed to go down to the upper 20's tonight. By Tuesday mid-day, the roads were clear, with hardly any ice anywhere. Watch for photographers! The snow-covered trees are spectacularly beautiful.
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	They were 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	The path was plowed from Kelly Circle to Route 9. There was a lot of snow at the intersection with Perkin St., but not so much I couldn't ride through it. The snow was starting to drift across the path by Daisy Field, just north of Willow Pond Ave., and in the wooded area to the north, several trees were so laden with snow that they bent to block the trail. There was only one I had to walk around, though. By Tuesday morning, all of the trees were above the 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	By Monday evening, the paths were mostly (except the very ends) plowed, but icy. I rode from Route 9 to Willow Pond with no problem.
Muddy River Path 12-foot-wide 0.6 mile shared bike/ped path with no intersections Brookline Park Department and DPW	The path was plowed, but there was an inch more of snow on top. It will probably be plowed again by sunset. It was easy riding. By Tuesday mid-day, the path was all wet pavement.
B.U. Bridge Easy connection to Charles River bikepath Department of Conservation and Recreation, Division of Urban Parks and Recreation	The upstream sidewalk was plowed to wet pavement all of the way.
Charles River Bikepath Narrow, shared bike-ped path with few intersections Department of Conservation and Recreation, Division of Urban Parks and Recreation	I cheered when the clear pavement (well, with a bit of snow on top) continued past the bridge sidewalk toward Magazine Beach. The path wasn't totally clear, but it was plowed almost to bare pavement most of the time. There were some snowy places, though. And at River St., the plowing stopped! I rode Memorial Drive to Western Ave. and hopped on the Harvard-maintained sidewalk on the inland side of the road. As far as I could see, the path wasn't plowed at all from River St. past Harvard Square. By Monday evening, the path was plowed from the Agassiz Bridge (JFK St./Harvard Square) to the BU Bridge, but a bit icy. Tuesday mid-day, it was mosly wet pavement. As of Tuesday, January 22, Jon Niehof reports that the path is well plowed to Watertown Square along Nonantum Road. I happened to ride it the same morning and found that it was clear to the Anderson Bridge, except for bad ice near the Northeastern Boathouse, at the wooden pier near the Publick Theater, and on the downstream side of the underpass under the Anderson Bridge. Ask the DCR to plow the *entire* path during or immediately after snowfalls by calling DCR Community Affairs at 617-626-4973, or email them.
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	This was bare pavement.
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	Unchecked, but probably clear.
Southwest Corridor Bikepath Separated Bike/Ped path with poorly-designed intersections Department of Conservation and Recreation, Division of Urban Parks and Recreation	Unchecked
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	No report yet.
Neponset Trail Mostly paved Bike/Ped path Department of Conservation and Recreation, Division of Urban Parks and Recreation	The park manager told the last Greenway Council meeting that he has been plowing the path, and it sounds like he has been pretty thorough. I haven't ridden it and would be interested in a report from anyone who has.
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 clear.
Danehy Park Paths City of Cambridge	Not checked, but probably clear.
Cambridge Bike Lanes Striped lanes of varying widths on major and connecting streets City of Cambridge	We got some of them back when the snows of 2007 finally melted, but this snow has narrowed the streets again.
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	Chris Porter reported that these sidewalks were plowed by Monday night.
Minuteman "Commuter Bikeway" Towns of Cambridge, Arlington, Lexington, and Bedford	Karin Turer reports: Arlington Heights to Center -- light dusting of snow on path, but completely passable and brakeable on a slick-tired mountain bike. The plowing of the path is the greatest thing since sliced bread! The trial plowing project is happening only in Arlington this winter--not in Lexington or Bedford. More details are 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. They are fun to ride during the first couple of inches of a fresh snowfall, though.
Assabet River Rail Trail Hudson and Marlborough, so far Town of Hudson, City of Marlborough (so far)	No report yet.
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.
