Alewife Brook Parkway - Route Description

Route Description

The southern terminus of the parkway is the western of the two Fresh Pond rotaries, where Concord Avenue connects the parkway to the Fresh Pond Parkway at the eastern rotary. The road is designated Massachusetts Routes 2 (northbound) and 16 (eastbound), and US Route 3 (northbound). The parkway run roughly north, skirting just east of the Alewife T station to a large intersection (formerly a rotary), where the limited access highway carrying Route 2 to the west begins. The parkway runs north from this intersection, paralleling just east of the course of Alewife Brook, which forms the western boundary of Cambridge with Arlington. The first major intersection is with Massachusetts Avenue, which carries Massachusetts Route 2A eastward toward Porter Square, and Routes 2A and 3 westward into Arlington. The parkway continues to parallel Alewife Brook as it heads north into Somerville. After crossing Broadway, the parkway passes through a rotary-like interchange with Powder House Boulevard. It then passes Dilboy Stadium on the left, and reaches its northern terminus at a small rotary near where Alewife Brook empties into the Mystic River. There it meets the Mystic Valley Parkway, which runs from Arlington just to the west to Medford to the northeast. The Route 16 designation continues northeast. The parkway's total length is just over two miles (about three kilometers).
