EXPRESSWAY SERVICE TO DOWNTOWN LOWELL: In 1959, the Massachusetts Department of Public Works (MassDPW) began work on the Lowell Connector, a 2.5-mile-long expressway connecting downtown Lowell with the Outer Circumferential Highway (I-495) and the Northwest Expressway (US 3). The $8 million expressway project was built as part of the I-495 contract through Chelmsford. It included the improvement of arterial streets leading to the Lowell Connector, relocation of River Meadow Brook, and the construction of an adjacent water purification plant.

Interchanges were built at the following locations:

  • Northwest Expressway (US 3)
  • Outer Circumferential Highway (I-495)
  • Industrial Avenue
  • Plain Street
  • Thorndike Street (MA 3A) and Lowell Center

The Lowell Connector was opened officially on October 24, 1962. However, the ramps to I-495 did not open until one year later, when the Outer Circumferential Highway was completed through the area.

BUSINESS SPUR I-495 ON THE CONNECTOR: When it opened, the Lowell Connector did not officially carry the Business Spur I-495 designation. The designation did appear, however, on signs erected in the 1960's. Many of the old "green 495" signs have been removed in the years since, although one remaining sign on a Lowell side street reveals the existence of the former designation.

THE LOWELL CONNECTOR TODAY: According to the Massachusetts Highway Department (MHD), the six-lane Lowell Connector carries approximately 50,000 vehicles per day (AADT). The MHD still maintains the I-495S designation on the connector, but only in planning documents.

Over the years, the Lowell Connector has gained notoriety of one of the most dangerous highways in the state. On average, the connector has a traffic fatality once a year over its 2.5 miles, which is about four times the average fatality rate of a typical freeway in Massachusetts. The connector's frequent entrance and exit ramps bear some of the blame, but much of the blame is placed on a lethal mix of high speeds and lower-than-average seat belt use.

During the early 2000's, the connector was resurfaced in conjunction with the nearby reconstruction of the Northwest Expressway (US 3).

This photo shows the October 24, 1962 dedication of the Lowell Connector at its northern terminus (EXITS 5A-5B-5C). Although records from its opening do not specify its designation, the Lowell Connector had the Business Spur I-495 ("green 495") designation during the 1960's and 1970's.
