Middlesex 3 is an ideal location in Massachusetts to live and work. Centered geographically within 15 miles of both Boston and Nashua, NH, the area’s location and infrastructure have enabled Middlesex 3 to attract high-quality and diverse businesses to the area.  The corridor has abundant and relatively low-cost real estate and a business-friendly climate. Our cities and towns work closely with the business community to provide resources and streamline the permitting process.
