The Trail So Far
Overview
The Bruce Freeman Rail Trail from Lowell to Framingham was divided into three phases. Currently, Phases 1 and 2 are complete (20+ miles), and Phase 3 into Framingham (4.6 miles) is under design.
Concord River Greenway, Connector Trail extends from the Bruce Freeman Rail Trail north from the Crosspoint parking lot into Lowell. This section of trail will be a link connecting the BFRT’s northern terminus, the 5.2-mile system of downtown Lowell Canalway trails, the Concord River Greenway and the Merrimack River Trail to New Hampshire, closing one of the very last remaining gaps in the regional 200-mile Bay Circuit Trail.
