Please join the Friends of Beaver Brook Reservation, Friends of the Western  Greenway, the New England Mountain Bike Association, and the Department of  Conservation and Recreation as they build over 3800 feet of new trail and  560 feet of new boardwalks in the DCR Beaver Brook North Reservation (formerly Met State Hospital) in Lexington. This work will complete the  Western Greenway link between the Metropolitan Parkway and the new Lot 1  property across Walnut Street to connect greenspace in Lexington, Belmont and Waltham. Tools, instruction, and lunch provided. Bring your bottle for bottomless  refills of ice water. Come for whatever part of the day your schedule  allows. Work goes from 8:30am to approximately 3pm on Saturday, September 26. New Improved Directions: If you know the area, take the Metropolitan Parkway North from Concord Ave Lexington or the Metropolitan Parkway South across from Forest St. at about 480 Trapelo Rd, Waltham and follow signs to trail  work. Parking is behind the abandoned administration building at  approximately here.  You can drive across the weed covered lots almost to the open gate in the  chain link fence if you vehicle ground clearance is not too low. Ignore the Googlemap verbal directions, there is no Doty St. This is the preferred  parking so we don't fill the residential neighborhood with cars. If you are unfamiliar with the area, use online maps or portable GPS to get  to Marguerite Terrace in Waltham, off Trapelo Rd, and park along the chain  link fence. The starting point is near the bottom end of Marguerite Terrace. A paved bike path also runs along the Metropolitan Parkway and can be  accessed from Trapelo Rd, Waltham or Concord Ave, Lexington.
