Built in the early 1960s and opened on October 24, 1962,[2] the Lowell Connector is located along the re-channelled River Meadow (or Hales) Brook.

[3] The Connector was officially named for the American Legion on May 20, 1963, a few months after opening; however, signs reflecting this were not posted until November 16, 2010.

However, there are no records indicating that this designation was ever approved by either the Bureau of Public Roads (now FHWA) or the American Association of State Highway Officials (now AASHTO).

[9] After three people died on the highway in 2005, MassDOT added median guardrails and multiple flashing warning signs giving the exact distance to the end of the road.

[10] In addition, the terminus features two flashing (strobe) stoplights and a metal railing, protecting the property at the opposite end of the intersection.
