The Gas Pump Canopy installation at the Brookfield Town Garage is substantially complete.  Officials say it will keep the users dry during inclement weather, and prolong the life of the pumping mechanism and controls. The canopy is lighted for night use when the Brookfield Public Works crews are out on snow plow duty during late night winter storms.  Meanwhile the state Department of Transportation has agreed to a request by the town for the part of the Still River Greenway abutting a state road.  The DOT will place a guardrail along Federal Road, coming into the Town Center.
