Route 16 is an east–west state highway in Massachusetts. It begins in the west at an intersection with Route 12 and Route 193 in Webster, just north of the Connecticut state border. It runs in a generally southwest-northeast routing through a number of Boston's suburbs and runs to the west and then north of the city before ending in Revere at an intersection with Route 1A and Route 60.

Much of Route 16 east of the Newton-Wellesley town line, and especially from Cambridge eastward, is a multi-lane parkway, although it is not limited access for any significant length of road. Segments of Route 16 are also known as the Mystic Valley Parkway, the Alewife Brook Parkway, and the Revere Beach Parkway, among other names.

From the western end of the Route 135 concurrency in Wellesley to Route 30 (Commonwealth Avenue) in Newton, the route serves as a part of the Boston Marathon, from the halfway point to just before Mile 18 and the hills.

Route description[edit]

From the shore to the Pike[edit]

Route 16 begins at the Atlantic Ocean at Revere Beach, where it intersects with Route 1A and 60 at Timothy J. Mahoney Circle in Revere.

The route proceeds west by a winding path through several mixed-used industrial, commercial, and residential areas through Revere (where it has an interchange with U.S. Route 1) and the cities of Chelsea, Everett and Medford until it intersects Interstate 93 in Medford. This portion of the road, east of Route 28 in Medford, is called Revere Beach Parkway. At Interstate 93, Route 16 veers north, traveling beside the Mystic River upstream, and passing near Medford Square, the downtown area of that city. The portion of Route 16 west of Route 28 and along the Mystic River is also part of the Mystic Valley Parkway.

The Mystic Valley Parkway continues west as Route 16 turns south in Somerville on Alewife Brook Parkway. This section of Route 16 soon joins U.S. Highway 3 and then Route 2 at the eastern end of the freeway portion of the Concord Turnpike. From there, Route 16 passes the large parking garage at the MBTA Alewife Station, passes by Fresh Pond, eventually leaving Routes 2 and 3 as they continue along Fresh Pond Parkway. It then continues west through Cambridge after briefly crossing into Arlington, passing by Mount Auburn Cemetery before entering Watertown. Route 16 crosses U.S. Highway 20 in Watertown Square, then crosses the Charles River. It enters Newton near the village of Nonantum, and eventually crosses I-90, the Massachusetts Turnpike, in West Newton; Pike Exit 16 here provides access to and from the east only. Still in Newton, Route 16 then crosses Route 30 and Route 128 (Interstate 95) before crossing into Wellesley.

From Newton to I-495[edit]

This area west of Boston, also called MetroWest, that Route 16 now travels through contains several quintessential New England towns. The route now goes by restored antique, colonial homes and town buildings.[2]

From the Pike, Route 16 goes southwesterly past Lasell College in Newton, and through Wellesley, where Wellesley College and Babson College are located and travels next to the Dover town line before crossing into Natick. The road then passes the Elm Bank Reservation in Sherborn, through Holliston, by Weston Pond, and shortly thereafter passes beneath I-495.

From I-495 to Lake Chaubunagungamaug[edit]

After passing I-495, the route continues to the southwest, going through Milford, Hopedale, Mendon, Uxbridge, the Blackstone River Valley National Heritage Corridor and Douglas with a trip through the Douglas State Forest in the last town.

Route 16 continues to its intersection with I-395 in Webster, along the shore of Lake Chaubunagungamaug,[3] and not far from the Connecticut border. Route 16 ends at Routes 12 and 193 just to the west.
