Streetscape Phase 3 construction in Brookfield formally kicked off with a ceremonial ground breaking yesterday.  The ground breaking was held by the Economic Development Commission in the grassy area in front of the new Dunkin location at 756 Federal Road, at the location where a small pocket park will be built. This phase, the third of six planned, also includes 2,100 linear feet of sidewalk, which will extend the Still River Greenway Trail to Laurel Hill Road.  13 sidewalk lights will be installed.  Significant landscaping and pedestrian-friendly amenities are also planned.
